Actually, the East Island and Far East Island are thinner than Dwilight. It's just that Dwilight hasn't had enough protracted civil wars to really break up the realms. It's got the cities to break it up a lot more, it just hasn't happened. Not enough people ruffling feathers I think. That and the Astroist realms didn't want to declare war on each other for fear of pissing off every OTHER astroist realm.
