Bonisagus
Bonisagus invented the Hermetic theory of magic, and his student Trianoma masterminded the formation of the Order, so this House has always enjoyed a great deal of respect from other Magi. Bonisagus Magi continue both the theoretical and political traditions, some refining and expanding Hermetic theory, others overseeing the continued political development of the Order. Most members of this House believe themselves to be of a privileged, gifted elite. However, they have a strong tradition for using their knowledge and power for the benefit of the Order. Selfishness is strongly discouraged.
