The yrak pootzck, a phrase implying impure parentage and cowardly ways, referred to those members of the Ubese species who had been rescued from their ravaged homeworld of Uba IV and relocated to the nearby Ubertica system, where they propagated and eventually found their way into the galaxy. The yrak pootzck engaged in a millennia-old bloodfeud with the so-called "True Ubese," those members of the species who remained on Uba IV to eke out a meager existence.
