[Lea has stayed silent on the subject of leadership until now, partly out of lack of having a real opinion on 'council vs no council' thing, but Kaiba's suggestion got his attention.]

I like Kaiba's idea about the 'divisions' or 'guilds' thing too. Makes a lot of sense with people coming in from so many different worlds; it'd make it easier for people with similar skillsets to get together and share ideas and stuff. Maybe come up with new ideas for things specifically suited to life on the train.
