Technology so advanced as to be indistinguishable from "magic", which appears to be miraculous in its workings; any godtech that cannot be understood by modosophont level science.
Clarketech is sometimes created or left behind by transapients and archailects, or - much more rarely - left by alien civilizations. Although most clarketech cannot be used by modosophonts for any useful purpose there are still a few instances where clarketech does work in a practical way (antigravity cloth, matter teleportation, etc.). Even 'useless' clarketech artifacts can fetch reasonably good prices on the open market, perhaps because collectors hope to eventually find ways of using them.
Because it has properties that cannot be replicated under normal circumstances, workable clarketech is greatly valued by galactic civilization. But like most artifacts, clarketech eventually wears out. For this reason, adventurers and entrepreneurs are always on the lookout for any new discoveries of clarketech, and countless fortunes have been made and lost in the search for this galactic grail.
The name originated from a famous saying by Arthur C Clarke -an Atomic and Early Information Age fabulist: Any sufficiently advanced technology is indistinguishable from magic.
Clarker - Text by M. Alan Kazlev Sentient who makes a living through sifting through marketplaces for unusual artifacts. The items Clarkers find or trade in are not necessarily clarketech, and most of them turn out to be hoaxes, counterfeits, or just cases of misidentification of common objects. But every so often, something truly rare and unique turns up. A single good find can set a Clarker up in the lap of luxury for life.
Disintegrator Weapon - Text by M. Alan Kazlev A very rare clarketech device, much more common in fabulist tales than in real life. Most actual disintegrators work in different ways, showing their origin as rare artifacts. Almost all uses clarketech effects that weaken the atomic bonds in the target so it vaporises in a huge ball of superheated gas. The range is not known to exceed 200 meters (more often no more than 50 meters), making it almost as dangerous to the user as the target Some weaken molecular bonds, some weaken atomic bonds (such as a weak force boson beam), the most powerful (probably never hand held) somehow separate the quarks from each other.
Godseed - Text by M. Alan Kazlev Generic term for any device that can bring about a radical ascension in the user's toposophic status, or the toposophic status of any sentient or sub-sentient to which it is applied. Many godseeds can exert a catastrophic effect on the user, or result in ascensions among the unprepared or maladjusted that result in perversities. For this reason the technology has become proscribed in many polities. Some well-known godseeds include Atzilut Sparkles, SNARE , the Olympus Pill, and Vinge's Revenge. There is a flourishing blackmarket traffic in godseeds, especially in less regulated regions of the galaxy.
Magic - Text by M. Alan Kazlev Apparent or claimed use of psychic (non-physical, non technological) powers to affect the outcome of physical events
Pseudoclarketech - Text by M. Alan Kazlev Technology that in all ways pretends to be, or appears to be, clarketech, but, although advanced, still shows itself to be amenable to study and reverse engineering.
Transcension Chasers - Text by M. Alan Kazlev Sentients, very often SI:<1, but sometimes higher toposophics, who spend their lives chasing Ascension and Transcension Events. They go around wearing these holographic T-shirts which play a little movie of the latest big transcendence they recorded, you know, an "I was There when the Croupe-Ngame B MicroCluster made the Big Exponential" They hold conventions, swap collectibles, show off their artifacts, that sort of thing...
