In addition to the skills chosen for a character, he or she is also subject to the development of character traits that are a direct result of their behaviour (i.e. - bravery, cowardice) or the situations they find themselves in (i.e. - alcoholism, madness, promiscuity, boredom or all of these things). A negative trait is acquired gradually from a certain pattern of behaviour and can usually be expunged by a continued display of the opposite behaviour.
In addition to skills, as characters gain experience they will acquire retainers - followers and items that further shape their personality and abilities. The retainers available at any one time are chosen from a pool existing on a per-province basis.
