Ok heres my race:
'The Ancients' as they are now known, occupy a small portion of the Galaxy, on the far reaches of the Western rim. They have long since forgotten the name once used for their race, for it no longer matters. In approximately 18,000 BC, Earth Years, The Ancients took to the stars after a long dark age. Their planet was devastated by radioactive material and nuclear fallout. For 3,000 years they had lived underground awaiting the end of a nuclear winter. Wen they emerged they discovered a lush and fertile planet. It seemed they had stayed underground too long, and the planet had long since been healthy. Never the less, they had learnt from their mistakes. Advanced technology allowed them to harness the power of the their sun. Thus The Ancients entered into their 'Age of Discovery'. Explorers, lead by the great Arman Desalat, stepped forth into the heavens. 500 years later their home system was completely colonized, sub-space faster than light travel had been developed, and explorers were discovering new habitable worlds on which they could settle. It also seemed to The Ancients that they were alone in the galaxy. The only space faring race. They had noted several tribal, and stone age species in their voyages. Notably, on a planet they called 'Prima Taura', a humanoid race, like them. Where they found semi-intelligent life they left probes, but they themselves would not return.
In Earth year, 10,000 BC The Ancient civilisation was no longer expanding through out space. They occupied most of the alot of the Western and Northern reaches of the galaxy, the pinacle of their existence had been reached. Technologically, they would be unrivalled for nearly 14,000 years but culturally they would remain unique. They were a pacifistic people, though this did not mean they would not fight in self defence. If all their defensive technology, designed to shield them and hide them failed, they would not run. They had their honour and dignity too. Though the time never came to use thier weapons. Not once in their history did they meet another space faring race. Then, around 9,800 BC their religious leader, Della Omnara became the first to achieve enlightenment. Thus began their Age of Enlightenment.
Enlightenment, was what The Ancients religion preached, awaited the worthy. Once you had reaced a mental and spiritual understanding so deep, you were no longer bound to the physical world and mortality. May Ancients regard this to be the beginning of the end. It seemed as though the entire race had reached its peak, many more achieving enlightenment. It is known that many of those who reached the ranks the Ascended migrated to the world the ancients had left alone, those with semi-intelligent races, where they live peacefully. Hundreds went to Prima Taura, and the other planets they located in the north and eastern reaches. Before the ancients left our galaxy they destroyed or hid their technology and cities, wishing only those worthy enough to find them. To this day only 2 planets remain inhabited by The Ancients. Visuban and Othalla. In the furthest reaches of the Western edge of the galaxy, far out of sight.
EDIT: Othalla then, and any other planet next to it, as Othalla I notice is already in there.
