All of your characters (except adventurers) are troop leaders: they start off the game with a unit, which they bring into battle and (hopefully) safely out again. The command of troops is a large part of each character's responsibility as a member of his or her realm.
Each troop leader (or "TL") who you play has a name, belongs to a realm, has a class, a rank, an age and receives an income in gold or bonds. More than that, each TL should have a personality and goals.
Each troop leader has inalienable rights which ought to be respected.
