Ximega I

Ximega I was a planet which was once inhabited by a race known as the Ximegans, and was located in or near Federation space.

At some point in the 22nd century, Ximega's local star went nova and the planet was destroyed. Fortunately, some portion of the Ximegan culture survived thanks to Prekraft, a scientist who had recorded everybodies physical and mental patterns, encoded them into holograms, and launched them off planet, before the nova claimed them all.
