History & Background (Dossier)

Contacts have been made at the spinward edge of this region with the Bolth, a non-hominoid serpentine race inhabiting the Zachrisson Subsector and thought to have originated in another galaxy.

The leaders of Hoganas in neighbouring Four Corners Subsector built highports in Yavakrbi at Syndet Landing, Rumio, and Andress Balfor. Shrines to the Golden Sovereign of Hoganas and an enthusiastic embassy are still present at the first two ports, but Andress Balfor dismantled the shrine and expelled the embassy when it nationalised its port in 1094.
