Reached1977 AT

Solar Dominion Inner Sphere system. Extensive orbital settlements extend throughout the system, and bubblehab colonies have been established in the atmosphere of all three gas giants.

The system was home of the Akirates, a heterodox offshoot of the powerful Stevens clade that arrived in 1977 AT. The system joined the Solar Dominion in 2866 AT.
