They were ruthless pirates whose homeworld was not known and whose history was devoted to conquest. While they were seen as war-like, the Ebruchi themselves tended to use small starships for travel rather than large fleets of bigger ships. Many believed that the race were barbaric nomads who had traveled in space for so long that they had forgotten, as well as forsaken, their planetary heritage.
Speciesism was a foreign concept to the Ebruchi. Members of other races made up parts of the pirate crews of the Ebruchi fleet and were considered Ebruchi as well. The most notable of these races were the Eickarie, Morseerian, and Tarro.
