Roisa is the second planet of the Vonaâsiâi (Twins) system. It was settled during 755 CY (YE 36).

Roisia is a frigid world that most of the surface is frozen water or permafrost. A narrow band along the equator actually reaches temps above freezing. There is very little deviation in the weather due to the slight axial tilt. The only external factor that affects the planet is the interaction of the Primary and Companion stars. There is a single settlement maintained by the Poku Saeruo Degonjo to gather resources.

Due to the low atmospheric pressure all structures are pressurized to standard. When working outside Poku'vonai use oxygen-increased respirators to avoid hypoxia. Working in the mountains they must wear pressure suits or space suits.
