They were called the 'Cholan-Re.' They were beings of great intellect, superior physique and technology akin to magic. They called their homeworld, "Earth." When their sun began to die, the Cholan-Re tried to build ships to outrun light and take them to new worlds. They failed. But in their failure they discovered their 'Earth' was one of several 'Earths.' They called the layered continuum they discovered 'The Multiverse.'
Building dimension ships, they traveled the Multiverse, settling worlds and building an empire. They were born of the most ideally evolved of the Earths. It was only logical that they should rule.
10,000 years ago...A dimensional ship opened a wormhole to a system deep in the Multiverse. When the ship translated to normal space, they made two important discoveries. The first was that the 'Earth' they were orbiting was inhabited! Several species, in fact, had crawled up their way up the evolutionary ladder to achieve sentience. The second discovery was just as important. They couldn't go home. Due to a 'white-hole transitive fixation' the wormhole they had opened only went one way. Once the truth spread to the hundreds of thousands of crew members, workers and colonists unrest began to foment. The unrest turned into a mutiny. The mutiny turned into a revolt. The dimension ship was sent careening toward the sun.
The survivors landed on the planet. The revolt turned into a hunt. The Cholan-Re masters were massacred. When no more of them could be found, the survivors joined the hunter-gathering natives of the world and sought to create new lives.
The planet "Yarth" has all the elements of an advanced society: cars, computers, cell phones, wars, politicians, sporting events, as well as people in all sorts of shapes, sizes and fur color.
The survivors of the revolt used their superior technology to shape society. Doing so has became as much a form of entertainment as a means to power. The children of the 'Survivor Clans' were taught the truth of their origin. And the Cholan-Re became bogeymen, a story used to frighten their sons and daughters to keep their origin a secret. Some of the the Cholan-Re survived. These 'Remnants' hid themselves more deeply than the Survivor Clans. They kept watch on the descendants of those that had murdered their fathers. And now, they have begun efforts to regain the control that is their birthright. The Cholan-Re Remnants have a new tool at their disposal.
They call it, "SoftMetal."
