The Hub Sector contains hundreds of star systems that are interconnected by a Hyperchannel network. The heart of the Hub Sector is The Inner Cluster, which houses the Hyperbol arenas and the massive Gateway Complex occupied by The Brotherhood. The Mars Gateway that used to link Mars with the Hub Sector is located within the Gateway Complex, but lies dormant alongside countless other dormant Gateways that lead to distant areas of the galaxy.

Stranded from Earth, the people of the Hub Sector are left on their own, with only the Factions to turn to.
