The lost world of Xebrik was the home world of the Kepek until they were forced to flee thousands of Bektep-Orbits ago. The history from so long ago is unclear, but the common belief is that the world was swallowed up by a rogue black hole.
Much about the planet was lost to time, save for a few planetary political maps, but legend says it was a paradise. It was a large planet that orbited a (relatively) small blue star with an overall hot climate. It was said that the planet had rings, which delayed the Kepek's attempts to reach space quite considerably. It did, however, lead them to advance as an ancient civilisation rapidly.
According to legend, the planet was bountiful, but the number of Kepek inhabiting it began to put a strain on the native ecosystems, spurring them into searching the stars to expand and eventually flee when it was clear their world was no longer safe.
