The Ebruchi were a sentient race that originated in the Unknown Regions. These humanoid beings possessed pale white skin and distinctive mouths encircled by worm-like tentacles. Living in the uncharted space, the Ebruchi formed a clan—based society. They controlled territory encompassing several star systems and patrolled the borders of the Outer Rim Territories and Wild Space, in search of unsuspecting prey. While primarily composed of Ebruchi, their ranks were open to individuals from other alien species within the Unknown Regions, often those who had been ostracized.
Their history was one of relentless conquest, and they operated as merciless pirates. The location of their homeworld remained a mystery. Despite their reputation for aggression, the Ebruchi favored smaller starships for transportation, rather than assembling large fleets of capital ships. Many theorized that this race consisted of barbaric nomads who had wandered through space for so long they had both forgotten and abandoned their original planetary roots.
The concept of Speciesism was alien to the Ebruchi. Their pirate crews included members of various other races, who were fully integrated and considered Ebruchi themselves. Among the most prominent of these were the Eickarie, Morseerian, and Tarro.
