I recall before the Large Hadron Collider at CERN, there was supposed to be the Superconducting Super Collider in Waxahatchie, Texas. It was there, we were supposed to discover the "God Particle," and cement American leadership in High Energy Particle Physics research. Though the 90's during the saw economic surpluses, low unemployment and a robust economy of legend, part of the belt tightening included base closures (Bergstrom Air Force Base, for one to the now International Airport in Austin) and sadly, the Super Collider. That unfortunate shortsightedness delayed the discovery of The Higgs Boson, and as Neil deGrasse Tyson observed, saw the exodus of that scientific discovery from the United States. My wife's cousin was an engineer on the project that when it ended, so did his employment at the time.

I am incredulous that we naively see America as #1, yet cede our technological leadership by shortsightedness, fruitless pursuit of pseudoscience and political expediency. Science is not decided in the deified "market"; it is typically not self-funded nor self-sustaining; the Moon Launches, Shuttle missions and ISS were not all crowd sourced on Kick Starter, nor will any future endeavors to the asteroid belt and Mars require only benevolent billionaires. Our current national investment is in soundbite phrasings; empty words spoken by leaders to "tickle the ears" of their constituents and ensure their reelection in the next cycle. There is a direct proportional correlation to technological proficiency; national wealth and prosperity. An American Super Collider would have paid for itself from the PhD researchers to engineers, cafeteria workers and janitors, taxpayers all. CERN gives tours, and likely inspire another generation of scientists and engineers; educators [and] politicians with scales fallen from their eyes, widened with wonder. That wonder and spin off prosperity could have been shared in what is now a cavernous crater to our impolitic actions, "deep in the heart of Texas."

In my story on advances in smaller-scale, privately funded fusion reactor projects last week (“Finally, Fusion Takes Small Steps Toward Reality”), I stated that “Companies like Tri Alpha offer a path to fusion paved not with taxpayer dollars but with private-sector money—which ultimately is the only way to actually get something built.”

I considered that statement rather innocuous, but many readers disagreed, going so far as to call it “libertarian claptrap.” The advances I wrote about, said BarryG, “were EXACTLY only possible because they were very LITERALLY paved with taxpayer R&D.”

For the record, I didn’t say that only private-sector money is needed to bring new energy technologies, like fusion, to market; it’s undeniable that decades of taxpayer funding have been necessary to get the basic research to the point where companies like Tri Alpha and General Fusion can pursue newer approaches that could, plausibly, attract private sector investment. Both are essential; one will never work without the other. The key is defining the inflection point, at which the technology is mature enough and demand is robust enough to create a viable market that’s attractive to investors seeking a reasonable return. Any market dependent on long-term government support to sustain itself was never really a viable market in the first place. The trick is clearly defining “long-term.” [1]

If all had gone according to plan, the gargantuan U.S. high-energy physics project would have already found the Higgs particle, having solidly won the competition with its European competitor. Peter Higgs, in fact, might have collected his physics Nobel a few years earlier.

The Superconducting Super Collider (SSC) that would have graced the rolling prairies of Texas would have boasted energy 20 times larger than any accelerator ever constructed and might have been revealing whatever surprises that lay beyond the Higgs, allowing the U.S. to retain dominance in high-energy physics. Except the story didn’t play out according to script. Twenty years ago, on October 21, 1993, Congress officially killed the project, leaving behind more than vacant tunnel in the Texas earth. [2]

Squitches...

The transistor – a switching element that defined technological progress through the 20th century – may be reaching its limits as demands for smaller devices continue. One alternative is the nanoelectromechanical (NEM) switch, but so far these have fallen short of the performance criteria required. Now an improved NEM switch based on tunnelling has demonstrated how these switches may yet be a viable contender to succeed the conventional transistor in low-power devices.

“To be competitive, the NEM switch operation must be made more energy efficient and reliable,” says Farnaz Niroui, a researcher at the Organic and Nanostructured Electronics Laboratory at the Massachusetts Institute of Technology in the US. “Our proposed tunnelling switching mechanism based on molecular thin films enables us to achieve drastic miniaturization of the devices to lower the operating voltages and provide nanoscale force control for more repeatable and reliable performance.”

Traditional electromechanical switches complete a circuit when the two electrodes are in contact, and break it – ‘turn off’ – when they are not. Scaling these elements down to the nanoscale offers a switching mechanism that may outperform conventional transistors in terms of the on/off ratio and low leakage current that can be achieved. However, operating reliably at low voltages requires control over the nanoscale distance between the electrodes that is tricky in itself, and further complicated by adhesive ‘stiction’ forces that cause the device to fail.

Here, the tunnelling approach appears to provide the answer for Niroui and her team at MIT led by Vladimir Bulović, Jeffrey Lang and Timothy Swager. They sandwich a self-assembled organic molecular film – poly(ethylene glycol)-dithiol (PEG-dithiol) – between the electrodes and modulate the tunnelling current through the film as it compresses and recovers.

Ain't Misbehavin'...

A display from the Large Hadron Collider's LHCb experiment shows the paths of particles such as leptons created in the collision of two protons at the accelerator. LHCb and another accelerator experiment, Belle, have found preliminary evidence that leptons do not obey the known laws of physics.

Right or wrong, the cultural reference to the blog title here.

At the smallest scales, everything in the universe can be broken down into fundamental morsels called particles. The Standard Model of particle physics—the reigning theory of these morsels—describes a small collection of known species that combine in myriad ways to build the matter around us and carry the forces of nature. Yet physicists know that these particles cannot be all there is—they do not account for the dark matter or dark energy that seem to contribute much of the universe’s mass, for example. Now two experiments have observed particles misbehaving in ways not predicted by any known laws of physics, potentially suggesting the existence of some new type of particle beyond the standard zoo. The results are not fully confirmed yet, but the fact that two experiments colliding different types of particles have seen a similar effect, and that hints of this behavior also showed up in 2012 at a third particle collider, has many physicists animated. “It’s really bizarre,” says Mark Wise, a theorist at the California Institute of Technology who was not involved in the experiments. “The discrepancy is large and it seems like it’s on very sound footing. It’s probably the strongest, most enduring deviation we’ve seen from the Standard Model.” Finding such a crack in the Standard Model is exciting because it suggests a potential path toward expanding the model beyond those particles currently known.

The eyebrow-raising results come from the LHCb experiment at the Large Hadron Collider (LHC) in Switzerland and the Belle experiment at the High Energy Accelerator Research Organization (KEK) in Japan. Both observed an excess of certain types of leptons compared to others produced when particles called B mesons (made of a bottom quark and an antiquark) decay. Leptons are a category of particles that includes electrons, as well as their heavier cousins muons and taus. A Standard Model principle known as lepton universality says that all leptons should be treated equally by the weak interaction, the fundamental force responsible for radioactive decay. But when the experiments observed a large number of B meson decays, which should have produced equal numbers of electrons, muons and taus among their final products (after the different masses of the particles are taken into account), the decays actually made more taus.

Schrödinger's Bacterium...

Topics: Biology, Quantum Mechanics, Schrödinger's cat, Superconductivity, Research


A proposal for putting a living bacterium into a superposition of quantum states has been unveiled by physicists in the US and China. If successful, the experiment would be the first realization – albeit microscopic – of Schrödinger's famous thought experiment involving a cat in a box that is simultaneously alive and dead until an observer makes a measurement by peering into the box. As well as improving our understanding of the foundations of quantum mechanics, the researchers say that their proposed experiment could also yield a new technique for monitoring defects in biological molecules.

Superposition is a quirky property of the quantum world that allows a physical system such as an atom or photon to exist in two or more quantum states, until a measurement is made on it. In recent years, physicists have created superposition states using inanimate objects of increasing size, from electrons and photons to atoms, molecules and even tiny mechanical systems. Now, Tongcang Li* of Purdue University and Zhang-Qi Yin of Tsinghua University propose doing the same thing with a living object – a tiny bacterium – to realize a version of Schrödinger's cat.

The proposal involves a tiny mechanical oscillator built by John Teufel and colleagues at the National Institute of Standards and Technology in Colorado. That oscillator is an aluminium disc 15 μm across and 100 nm thick that forms the upper plate of a capacitor within a superconducting inductor-capacitor (LC) circuit. In 2011 Teufel's group was able to put the mechanical oscillator in its quantum ground state. This was done by first cooling the apparatus in a cryostat and then subjecting the oscillator to "sideband cooling", which involves coupling its mechanical vibrations to microwave radiation.

* Dr. Tongcang Li was Dr. Mark G. Raizen's former PhD student, University of Texas, Austin; my distinct honor to know both gentlemen.

No, "The Force is [not yet] with us Young Skywalker," but it is an interesting application you might soon find on your next gadget purchase, i.e. using photons instead of electrons switching states to carry information.

It’s not lightsaber time, not yet. But a team including theoretical physicists from the National Institute of Standards and Technology (NIST) has taken another step toward building objects out of photons, and the findings* hint that weightless particles of light can be joined into a sort of “molecule” with its own peculiar force.

The findings build on previous research that several team members contributed to before joining NIST. In 2013, collaborators from Harvard, Caltech and MIT found a way to bind two photons together so that one would sit right atop the other, superimposed as they travel. Their experimental demonstration was considered a breakthrough, because no one had ever constructed anything by combining individual photons—inspiring some to imagine that real-life lightsabers were just around the corner.

Now, in a paper forthcoming in Physical Review Letters, the NIST and University of Maryland-based team (with other collaborators) has showed theoretically that by tweaking a few parameters of the binding process, photons could travel side by side, a specific distance from each other. The arrangement is akin to the way that two hydrogen atoms sit next to each other in a hydrogen molecule.

Exploring Physics...

A group of educational researchers have created an app for iOS, Android, PCs, and Macs, to teach physics to 9-graders. I'm a strong advocate of Physics-Chemistry-Biology, the reverse of how science is taught in high schools now.

The app, Exploring Physics, is meant to take particular physics curriculum already being taught in a number of public school districts, including Columbia's, and make it available digitally. The Exploring Physics curriculum app is designed to replace traditional lecture-based learning with discussions and hands-on experiments.

“The idea in the app is to have students learn by doing stuff,” said Meera Chandrasekhar, the co-creator of the app and a curators' teaching professor in the MU Department of Physics and Astronomy. “Even though it’s a digital app, it actually involves using quite a lot of hands-on materials.”

I thought this was a neat app to have and use. Teachers: See if your districts fund this for you. Students: You're likely not going to be able to use it DURING exams. Use it to reinforce your understanding of lecture and notes. The best apps of all are your eyes, ears, attention and participation.

Again, I get nothing except one, self-serving thing: a replacement workforce for when I retire. Call it my "school-to-STEM" pipeline.

Brain Freeze...

A scan of a young woman’s brain after being frozen.


Topics: Biology, NASA, Pseudoscience, Science Fiction, Space Exploration


A staple of science fiction on Einstein-relativistic terms has always been "sleeper ships," as you'll see at the link, NASA has funded a study. You'll see them in Star Trek or the Alien/Prometheus products, and most recently Interstellar. Essentially, you would go into a hibernation, whereby your vitals would be slowed to a crawl, and things like power, lighting and food for long journeys would be minimized, at least until so-called warp drive. Like Rumpelstiltskin, you would wake up out-of-time, but farther (and further ahead in time) than where you'd started. Brief sleeping and wake periods for say, a trip to Mars, this still may be possible. The other staple of speculative fiction is uploading oneself to a state of continuance/immortality. This article seems to throw some shade on such a special iconic wish, which may turn out to be just that...

I woke up on Saturday to a heartbreaking front-page article in the New York Times about a terminally ill young woman who chooses to freeze her brain. She is drawn into a cottage industry spurred by “transhumanist” principles that offers to preserve people in liquid nitrogen immediately after death and store their bodies (or at least their heads) in hopes that they can be reanimated or digitally replicated in a technologically advanced future.

If we could “upload” or roughly simulate any brain, it should be that of C. elegans (Caenorhabditis elegans, or roundworms). Yet even with the full connectome in hand, a static model of this network of connections, or connectome, lacks most of the information necessary to simulate the mind of the worm. In short, brain activity cannot be inferred from synaptic neuroanatomy.

Diverse Video Game Streamers - Twitch and Youtube

Those of us who are gamers in this day an age all know of the recent sensation of video game streaming. Now that streaming services like Twitch and YouTube Gaming are available, we are seeing a new wave of content providers in the video content realm.

As a steamer myself, I'm amazed at the collectives and efforts that have been achieved by popular streamers such as Tessachka, Ducksauce, and more as they've managed to gain huge followings where people constantly donate and subscribe to their channels.

In that effort, I've noticed that there aren't any premiere PoC's in that realm...yet. In my strive to be one of thos chosen few, I've teamed up with #TheNetwork via NERD DIGITAL FANZINE, Ladies Of The Round Table, and #DiversifyStreaming2k15 in order to get a bit of exposure for the streaming that I do myself as well as the diverse group of fellow streamers that I've met and network with.

I'd love to try and get this group of streamers together with black game developers so that we can do what is being done with other independent games out there. Exposure on both fronts as well as interviews and simply promoting each other!

Please help out and share if you are in the gaming community. We'd love to get a large community of talented streamers, game devs, and content creators together so that this networking thing can be positive!

Saturn's Moon Enceladus...

A global ocean lies beneath the icy crust of Saturn's geologically active moon Enceladus, according to new research using data from NASA's Cassini mission.

Researchers found the magnitude of the moon's very slight wobble, as it orbits Saturn, can only be accounted for if its outer ice shell is not frozen solid to its interior, meaning a global ocean must be present.

The finding implies the fine spray of water vapor, icy particles and simple organic molecules Cassini has observed coming from fractures near the moon's south pole is being fed by this vast liquid water reservoir. The research is presented in a paper published online this week in the journal Icarus.

Previous analysis of Cassini data suggested the presence of a lens-shaped body of water, or sea, underlying the moon's south polar region. However, gravity data collected during the spacecraft's several close passes over the south polar region lent support to the possibility the sea might be global. The new results -- derived using an independent line of evidence based on Cassini's images -- confirm this to be the case.

"This was a hard problem that required years of observations, and calculations involving a diverse collection of disciplines, but we are confident we finally got it right," said Peter Thomas, a Cassini imaging team member at Cornell University, Ithaca, New York, and lead author of the paper.

Heavily Al+ Implanted 4H-SiC...

Comparison of (a) the Hall hole density and (b) the Hall hole mobility for 3 × 1020 cm−3 Al + implanted and 2000 °C/30 s MWA 4H-SiC samples, which are different only for the implantation temperature: (close symbols) 300 °C and (open symbols) 400 °C. The experimental data were corrected for contact size systematic error (see text).


Topics: Consumer Electronics, Economy, High Energy Physics, Ion Implantation, Semiconductors

Abstract


The processing parameters which favour the onset of an impurity band conduction around room temperature with a contemporaneous elevated p-type conductivity in Al + implanted 4H-SiC are highlighted by comparing original and literature results. In the examined cases, Al is implanted at 300–400 °C, in concentrations from below to above the Al solubility limit in 4H-SiC (2 × 1020 cm−3) and post implantation annealing temperature is ≥1950 °C. Transport measurements feature the onset of an impurity band conduction, appearing at increasing temperature for increasing Al implant dose, until this transport mechanism is enabled around room temperature. This condition appears suitable to guarantee a thermal stability of the electrical properties. In this study, the heaviest doped and less resistive samples (Al implanted concentration of 5 × 1020 cm−3 and resistivity of about 2 × 10−2 Ω cm) show a carrier density above the Al solubility limit, which is consistent with at least a 50% electrical activation for a 15% compensation. The model of Miller and Abrahams well describes the resistivity data of the lower doped sample, whereas a deviation from the behaviour predicted by such a model is observed in the higher doped specimens, consistent with the occurrence of a variable range hopping at low temperature.

Andrea Alù, an engineering professor at the University of Texas at Austin, has an amazing job description: he makes things invisible. Alù is a leading innovator in metamaterials, artificial materials with properties that allow electromagnetic waves to wrap around them. Those include radio waves--creating the possibility of more efficient antennas--and, at a very small scale, even the light waves that our eyes perceive. That light-bending technology could allow for the creation of microscopes with drastically improved performance. For his work, the National Science Foundation presented Alù with its 2015 Alan T.

When I was a student at North Forsyth High School in Winston-Salem, North Carolina I had the distinct pleasure of taking Air Force JROTC under Lieutenant Colonel Eugene Moody and Senior Master Sergeant Roland S. Wilkins. Surprisingly, I didn't come out of the class a warmonger - both gentlemen were veterans of the Vietnam conflict (and, had no stomach to repeat it), most of the lessons were a combination of Social Studies and Civics. What impressed me was that our democratic republic was special and unique; that in order for it to exist, "We The People" have to be a part of it. How we participate in it is not merely by voting alone, it's informing ourselves on the processes and procedures of divided government. That is commensurate with an informed citizenry, hence the importance of education to make the modern state function.

It is now fourteen years since the attack on these shores, this generations' "Pearl Harbor moment." I remember where I was: in a Motorola cafeteria in Austin, Texas, seeing the first then second plane hit the twin towers; terrified a third hit the Pentagon and Flight 93 was bound for either Capital Hill or the Executive Mansion. I now film a memorial, after a day with friends at NBC Universal/SNL studios, walking around this surreal site. I thought at the time of wanting to talk to my father, who had sadly been deceased for two years then. There were some that wanted our collective nightmare to steel the resolve of a public so diverse in perspectives and experiences that we would be unified; a truly "United States." That didn't last very long. We quickly sequestered ourselves into comfortable tribal groups - the non-religious and religious; the STEM and science phobic; the skeptic and conspiracy provocateurs; the lucid and irrational - all of the negative clusters led by narcissists addicted to sycophantic devotion. Some of them lead talk shows, reality shows or run for president.

"Democracy is not easy, and not everyone can do it right," Sergeant Wilkins said. Realize, the world wasn't so politically correct, as the statement could have some negative connotations today. [He explained] you have to be involved in your government; that you ARE the government. The assumption of public education, for example, is not just to prepare you to work in a job or profession: its primary mission is to prepare the body politic - "US" - to function as involved citizens; to hold power accountable. Public education is not merely reading blogs and reacting to soundbites formulated for manipulation and effect: it's in the reading of books - electronic, comic and papyrus - for pleasure as well as information, pondering deeply what they mean; what the authors of fiction and non-fiction were trying to say. Knowledge, books, access to them and literacy are the hallmarks of democracies and republics.

I will never be a proponent of charter schools or corporate education beyond merely investment in the Common Good. Education should not be just job preparation or an investment for dividends; it should be citizenship and critical thinking training. If the return on investment is a mindset that is so departed from logic and reason; if there is an insistence on pseudo-controversies that have been confirmed false or true by science over and over; when volume and trolling replaces debate - which in its purest sense, presupposes you have a point and feel confident you can make it in a civil manner; you don't have a state: you have a mob. To have more than this, to maintain this fragile construct called a democratic republic: we all need the resilience to accept the responsibility of being educated citizens, not entertained, bewildered sheep. We will quite naturally, demand more of our media; our current and future leaders when we start demanding more of ourselves.

“We were keeping our eye on 1984. When the year came and the prophecy didn't, thoughtful Americans sang softly in praise of themselves. The roots of liberal democracy had held. Wherever else the terror had happened, we, at least, had not been visited by Orwellian nightmares.

"But we had forgotten that alongside Orwell's dark vision, there was another - slightly older, slightly less well known, equally chilling: Aldous Huxley's Brave New World. Contrary to common belief even among the educated, Huxley and Orwell did not prophesy the same thing. Orwell warns that we will be overcome by an externally imposed oppression. But in Huxley's vision, no Big Brother is required to deprive people of their autonomy, maturity and history. As he saw it, people will come to love their oppression, to adore the technologies that undo their capacities to think.

"What Orwell feared were those who would ban books. What Huxley feared was that there would be no reason to ban a book, for there would be no one who wanted to read one. Orwell feared those who would deprive us of information. Huxley feared those who would give us so much that we would be reduced to passivity and egoism. Orwell feared that the truth would be concealed from us. Huxley feared the truth would be drowned in a sea of irrelevance. Orwell feared we would become a captive culture. Huxley feared we would become a trivial culture, preoccupied with some equivalent of the feelies, the orgy porgy, and the centrifugal bumble-puppy. As Huxley remarked in Brave New World Revisited, the civil libertarians and rationalists who are ever on the alert to oppose tyranny "failed to take into account man's almost infinite appetite for distractions". In 1984, Huxley added, people are controlled by inflicting pain. In Brave New World, they are controlled by inflicting pleasure. In short, Orwell feared that what we hate will ruin us. Huxley feared that what we love will ruin us. This book is about the possibility that Huxley, not Orwell, was right.”

Light Sails Leakage...

Image Source: MIT Technology Review


Topics: Astronomy, Astrophysics, Instrumentation, Space Flight, SETI, Solar Sail


Please note the emoji: \\//_. That Trekkie cred set: It's probably going to be a lot easier to detect civilizations closer, but slightly past our stage of admitted technological adolescence, currently beset and hindered by fear of all things science and willful ignorance. With the noted exception of Star Trek, most of the science fiction I'm reading recently stay in the Einstein-relativistic-speeds range, along with the effects of time dilation to their plot twists. If an intelligence has begun to at least explore their own outer planets, maybe...just maybe there's hope that we'll survive our own hubris.

TECHNOLOGY REVIEW: Light sails are a promising way of exploring star systems. If other civilizations use them, these sails should be visible from Earth, say astrophysicists.

Abstract


The primary challenge of rocket propulsion is the burden of needing to accelerate the spacecraft's own fuel, resulting in only a logarithmic gain in maximum speed as propellant is added to the spacecraft. Light sails offer an attractive alternative in which fuel is not carried by the spacecraft, with acceleration being provided by an external source of light. By artificially illuminating the spacecraft with beamed radiation, speeds are only limited by the area of the sail, heat resistance of its material, and power use of the accelerating apparatus. In this paper, we show that leakage from a light sail propulsion apparatus in operation around a solar system analogue would be detectable. To demonstrate this, we model the launch and arrival of a microwave beam-driven light sail constructed for transit between planets in orbit around a single star, and find an optimal beam frequency on the order of tens of GHz. Leakage from these beams yields transients with flux densities of Jy and durations of tens of seconds at 100 pc. Because most travel within a planetary system would be conducted between the habitable worlds within that system, multiply-transiting exoplanetary systems offer the greatest chance of detection, especially when the planets are in projected conjunction as viewed from Earth. If interplanetary travel via beam-driven light sails is commonly employed in our galaxy, this activity could be revealed by radio follow-up of nearby transiting exoplanetary systems. The expected signal properties define a new strategy in the search for extraterrestrial intelligence (SETI).

(Into the first string of Bounded Ages)

When the Dragons of the Sainted Mounts came to dwell in the eighth infinite realm some seven millennia ago, lured by its incontestable majesty, the land was already ancient, already ages old, already teeming with a vast array of Elemental kind. Yet, the leave given those repentant beasts, those Dragons, by the governing godheads—to walk the mortal demesne and know life, to roam its set skies and find freedom in flight—came with a price. The tribes of the realm’s center most Divide, unlike their primarily fey southern neighbors, were without hereditary Right, and the nurture and defense of those incapable societies became the Dragons’ cost.

Stymied, those monstrous converts instead conferred a wide range of magics unto five of the thirty or so tribes in existence. In due course, the Lŷʈīr of the sea brushed plains, the Hĕʈädĕlră of the low lying woodlands, the El’sŭūr of the arid western cape, the Hĕmĕt of the bountiful east, and the Aɽmūr of the lush center lands were accorded the ability to transform themselves into the various beasts of the realm. Too, came psychical abilities, such as the prized art of divination—along with an essential wisdom that would eventually allow them to subvert destiny—and the uncanny power to speak into the minds of their fellow men, influence and control them. Yet further, they were granted the secrets to alchemy and necromancy.

The last of the critical Dragon Epochs was brought to a stuttering close by the Reign of the Un-Righted—a minor period that marked the Icarian horde’s first occupation of the Central Divide. That swift and irreverent Reign spanned but a paltry seventy years, yet its effects were far reaching. Elemental kind and the natural mystics descended of them became nearly as lore in the two millennia that followed those transforming seventy, and far less commonplace were those born Righted. Moreover, the Magian tribes, as they eventually became styled, chiefly the El’sŭūr and the Hĕmĕt, became as a scourge to the Central Divide and very nearly to the entire realm. What a stunning travesty of the human spirit were those millenniums, those seven hundred twelve thousand Days of Roving Dissension, for they saw the Sourced Magians become dissolute in regard to their magics, saw them gorge themselves upon that which had been conferred them—and it was that singularly minded greed that brought about the end of the Dragons, with but a lone beast escaping their treacherous thirst for power.

Principally, as the Historicists say, the Days of Roving Dissension began as an almost post-traumatic response to the Icarian occupation. Unsurpassed as their magics became, Magians were not without vulnerability. The brand of power bestowed them was dark, and bore the capacity to injure or kill a Magian in expenditure. In counter, Magians began to channel their magics into tangible articles—scepters, amulets, and less often rings and other forms of metallic jewelry, objects which gained in power as they were handed down from conceder to heritor—and devised a vernacular, Ashvelsūrin, for use in summoning their strengths. Therein, however, lay their debility, for Magians could no longer access their magics once whatever bespelled article that was imbued with their power had been destroyed.

The ruthlessness of the Icarian saw that vulnerability exploited and Magian numbers, long among the smallest tribes, dwindled. In desperation, the Magians turned to the Dragons, but over the long centuries the creatures had grown complacent, disavowing all responsibility to the tribes and retreating into their cavernous dens. Angered, the Magians slew one of the Dragons—Helspeth the Halcyon, a slovenly, solitary thing that had slept for decades in the base of Mount Sale. By way of their contrived spellcraft, the Magians infused the glowing core of Helspeth’s power into a scepter, and with that receptacle’s aid, drove the Icarian from their lands.

Fearing an eventual discovery of their deed and the retribution to be faced, the Magians began to slay the Dragons, waging a war that lasted nigh on a millennium—a war that waxed and waned as the scepter, that much coveted Harvester’s Wrath, changed hands. When but a single Dragon remained—he, Eldevel of the Forbidding Star—the Lord Dragon, truly one of the Earthbound Gods of that larger, illustrious Era, descended from the highest point of the Mountains of Fire, where that fettered godhead had for nigh on six millennia taken his repose. His immense figure eclipsing even that of Eldevel, largest and most fearsome of all the beasts, the Lord Dragon spoke unto the Magians, offering pact and prophecy.

GendeshGoddess of the August Abodethe one called Harvester of Soulsbrought forth unto this realm the Dragonsfor heretofore the first Dragon Epochthey were among the many creatures who guard the Depths of DeathIt was Ithe Lord DragonGod of the Burning MountCrafter of the Temporal Formwho gave unto them their finite structures and consigned them act as protector and pedagogue to man.

As I sleptthe Dragons became self-content, shirking and delegating their duties.

The time will comehoweverwhen once more you find yourselves at your most desolate and you will face the Sainted Mounts and cry out towards thembeseeching aidNone will be forthcomingyou will have rid the realm of DragonsToo, the Era of the Earthbound Gods nears its endwe who are fettered must retake our place amongst the divineSpare this DragonEldevelso that when the time of chaos descends againyou shall through him your salvation find.”

We fear his vengeance,” one among the Magians thinly returned.

Then he shall be bound by obsidian and cast in the Enduring StoneThereEldevel will remain until summoned.”

We possess not the power to influence him”—this from that same Magian. “How will he then be swayed?”

Bring forth five maidens born of those Un-SourcedThey will bear unto you the means of Eldevels summoning and command.”

The Magians presented the Lord Dragon his behest— maidens taken from the Qĕss and the Nălẏr, the Arĕspús and the Dîrînîkă, and lastly the Nǽÿmīr—and he transformed himself into the semblance of a man. He lay with the young women, and upon that very eventide, they bore him each a babe—three sons and two daughters.

I give unto this realm ThérünÁninaXáelIthéanaand Arŏmilthe Dragon Righted who are Dæmonīækĕlwho are possessed of Rights comparable to your own magicsof the Right to call forth the Dragon of the Forbidding Star from his prison of glasshis casing of stoneand of the Right to speak into his mind, to influence and sway him.”

The Magians fell to their knees in obeisance, crying out.

Harken to me!” the godhead necessitated. “Punishment for your misdeeds has not escaped you and the destinies that were once writ for the tribes have now accordingly changedThere are those of you who will repentand in so doingwill find pardon and favor when the time of chaos descends again.

Toothere are those among you who will forever seek to procure that which was never intended for youand when you cannot procure ityou will then seek to bind it to youand when you cannot bind ityou will then seek to destroy itand when you cannot destroy ityou will then seek to make it obsoleteAge into agethe truth of your natures will be revealed and there will be further division and dissension among you as your magics become congruently defined.” Reverting to his imperial dæmonic form, the Lord Dragon then gave edict in a grating and infernal parlance—« HEED ME! »— before speaking yet other words which no tongue but that a blooded god’s can form.

Words that caused the Magians to bend their bodies over the ground, quaking and screaming as they covered ears that had suddenly become blistered and bled. Words that caused lightning to flash across the darkening sky—lightning which then raced down to strike the Dragon’s blood that soaked and stained the sand, turning it to salt. Words that bound Eldevel in obsidian and preserved him in the Enduring Stone. Words that opened the eyes of the newly birthed babes—eyes that brought frightened tears to their mothers and instantly entranced them. Words that returned the five young women and their godkind progeny into the protective folds of their respective tribes.

The Lord Dragon then ascended to the highest peak of the Sainted Mounts and spreading his massive wings, took flight, vanishing into the cosmos.

Talante, for 10,000 years has governed his clan like a father in the endless war with their hated enemy over the fate of humankind. One winter’s night, he chances to meet Amelia Grayson, a human whose blood arouses his desire, and whose presence arouses his compassion in a way no mortal ever has before. Distracted and terrified by all but alien emotions and instincts by this burgeoning bond in a prelude to what may be his clan’s most desperate hour, Talante is caught between duty and desire, until he is forced by choice and circumstance to decide whether to hold to the one he has grown to love more than his immortal life, or in spite of the cost, let go for the sake of his people and Amelia’s safety, in spite of twofold danger: one from a ravenous enemy that has hunted her kind for millennia … and the other from the seductive bond that would make her forever his, body and soul.
