Harmony, balance, moderation. Temperance would advise you not to invest too heavily in any outcome, to remain calm and to see all possible futures as opportunities for growth. Even the ones where everyone dies horribly.
Temperance comes after Death, you are reborn more temperate. Most people who follow Temperance have undergone some hardship or trial that allows them to see the reality of life.
Paladins of Temperance fight with a calmness of mind.
