Seat of Power:
This is a Gold System. Shogunate recognised claim over Shikoku provides the clan Daimyo with an additional vote during Shogunate debates.
Gate Keeper
Shikoku is the primary trade artery into Kusari from both Rheinland and Liberty. The Daimyo who controls it will be able to heavily influence trade from the 3 houses. The controlling clan will need to balance profits and risk, heavily taxing corporate vessels may result in heavy forces being deployed to protect convoys, not taxing enough will leave deep holes in their pockets whilst filling the coffers of foreign houses.
Advanced Traits
The Unquestioned Gate Keepers,
Not only does the current ruling clan control Shikoku but they also hold residence in both bordering systems, Kepler and Galileo. Having the entire belt locked down puts them in the perfect position to control a large portion of what comes into and out of Kusari. Will they engage in rampant piracy or strike deals and forge new alliances with foreign corporations? Either way, their clan should be profiting.
