Your Requiem is how you behave in Kindred society. These are deliberately broad categories. During character generation you will type "+requiem <Requiem>" to set your choice from the following list:
Courtesan: the life of the party, politically neutral fixer, and social engineer;
Enforcer: imposes order and stability with violence or the threat of violence;
Horror: the terrifying outsider who reminds Kindred of what they try to forget about themselves;
Manipulator: practically the default option. Plots and schemes;
Martyr: soulsick with regret and in search of redemption;
Nomad: freedom and wanderlust at the cost of never really belonging anywhere;
Magus: obsessed with the occult, either the vampiric condition or woojie powers.
