Xnar

Xnar (or Barnard 33E3) was a inhabited planet located in the Horsehead Nebula. It was a isolated planet due to the xenophobic Xnarians and it's deep location in the Horsehead Nebula.

Xnar had a similar, although not full identical, geology to Class-M mars, the only difference was that it had 1 super-continent and 3 other geological bodies on the other side.

History
Xnar was inhabited by a advanced species known as the Xnarian Progenitors millions of years prior to 3rd millennium. They flourished themselves possibly across multiple star systems. Although millennium before the exohominids of present day Xnar came into existence, these progenitors lost their ability to die, experience the mystery of death and other eschatological and thanatological beliefs.

It was theorized that the Progenitors created the Xnarians as a successor to themselves, but created the Xnarian Meta-consciousness Machine. A highly sophisticated machine which caused all Xnarians and Non-Xnarians, pre-mature or mature, on any Xnarian World to be downloaded into a supercomputer on a planet tens of thousands of light years away. This machine was active for 32,000 years but only was discovered 230 years prior to the 2470s.

Somewhere around the early Pliocene Epoch on Xnar, the current day Xnarians came into existence and the Progenitors most likely became intergalactic or went extinct in some natural process.
