Unnamed Alien Species

In 2368 AD the Terran Federation discovered a world with indications that an advanced alien species had inhabited it, and was able to exploited the resources of the planet and the solar system.

This species had no name because it had been ruthlessly wiped out; initially the Terran Federation believed that the species had wiped itself out in a suicidal fury, but it was later discovered that they had been deliberately destroyed by the Gbaba.
