Selruvian biome
The area known as the Selruvian biome corresponded to sector 8022 on the manufactured planet called Iokath. During the year 3630 BBY, ARIES ensnared the leaders of the Alliance on Iokath, specifically trapping both the Alliance Commander and Torian Cadera within the confines of the Selruvian biome.
