The Burvixese were a civilization of turtle-like aliens who once lived on a swampy world of Arcturus I. They were a benevolent and wise race who, instead of travelling between stars, talked with other races via HyperWave in the safety of their own homes.
The Gg had been following the attacks of a murderous race known as the Ur-Quan Kohr-Ah and, to their horror, noticed that the Kohr-Ah were closing in on them, apparently following the trail of their Hyperwave transmissions. Before their end came, the Gg warned the Burvixese of the danger, and the Burvixese in turn warned their closest neighbours, the Druuge, whom the Kohr-Ah had already noticed.
But the Druuge did a truly evil deed to ensure the salvation of their own wretched civilization: immediately, they shut down all their hyperwave transmitters and sent their fastest ships to the moon of the Burvixese homeworld. There they planted a powerful Hyperwave caster. The Kohr-Ah turned their interest from the Druuge to the homeworld of the Burvixese, who were eradicated in three days of orbital bombardment.
The arrival of the Ur-Quan Kzer-Za into the same area of space prompted the immediate resumption of the Doctrinal War, and the Druuge, having brought about this ghastly second-hand genocide, were forgotten by the Kohr-Ah in what followed.
