The League of Navigators, informally named "The Hyperspace People", is a neo-feudal society centered on "Bricks". The large Carriers, most of which having been produced off of blueprints, were found to have excellent amounts of cargo to carry people and goods, and so a commercial enterprise began.

As it turns out, being able to deliver anything anywhere in Sirius in a matter of minutes is a big deal, and so The League's constituent merchant captains were able to make a mint. The legacy of the old group of smugglers, scientists, and explorers that made up the core of The League still sticks around, and so The League is often fascinated with pushing beyond the limits of Sirius. With their Horizon-pattern Jump Drives, they have been able to completely shun all Ageira and Ageira-derived technology. Relieved of this onerous burden, their fuel costs were expected to shoot into the metaphorical stratosphere, but they could just pay off regular runners to do the actual planetary stuff within Sirius. Not using the Trade Lanes and Gates, while appearing on paper to be a major slowing factor, would not really affect them due to Colossus doing the heavy calculation work.

The Colossus Intelligence Engine is the heart and soul of the League's Carriers: Due to advances in the field of psychic communication, Colossus allows for League Carriers to instantaneously communicate with one another, serving as a gestalt consciousness across all the Bricks.

The Fukuda System is somewhat similar to the Babylon Sector, albeit located deep within the Barrier. The expeditionary fleet consisting of Mama Brick, Magic Brick, Maximum Brick, Lucky Break, and Rush Job arrived in the system in late 825 A.S. and began evaluating the system for a full-scale colonization effort. Time would tell if things would go well. At least they got a shipyard up and with their Horizon-pattern Drives, they, and they alone, could access the System. Whatever you think goes on in there is what goes on in there.
