The planet Arcturus I is a Redux World orbited by a single moon in the Arcturus star system. The planet has a damp surface with several swamps and was, until recently, the home of the Burvixese. An incident involving the Druuge, a HyperWave ´Caster, and the Kohr-Ah ended the Burvixese race's existence in 2142 after three days of consecutive, merciless orbital bombardment. There are ruins of many a great city on the planet's surface, now reduced to mere radioactive slab by a weapon clearly of Ur-Quan design. The ruins are a grim testament to the killing power of the Ur-Quan Kohr-Ah.
