They are always thirsty for domination, with a visceral need to have someone or something to dominate. If you can't take or keep the power, you are weak and worthless. For them, power should only be wielded by the 'worthy', and to prove yourself worthy, you simply need to take and control said power. They are 'elegant and inhuman predators', who believe in the sentence 'might makes right'. Their most defining trait? Their social darwinism.
They are the 'leaders' of the Sabbat, their economical and political force, their administration. The Night Clan, the Abyss Mystics, the Magisters, the Shadows, the Traitors.
