Bonisagus

House Bonisagus, named for its brilliant founder, is the first House of the Hermetic Order. Its members are divided into two subhouses: the Bonisagans, who pursue advanced, specialized magical studies; and the Trianomans, who pursue the politics of the Hermetic Order. It is a Lineage House, meaning that every member is descended by apprenticeship from Bonisagus or Trianoma.

In the Rhine, House Bonisagus is led from the covenant of Durenmar, located at the edge of the Black Forest in the southern center of the Tribunal. Durenmar is the largest covenant in the Rhine and hosts the Tribunal gathering every seven years.

The current leader of the Bonisagans is Hypatia, a driven and dedicated scholar with limited social skills. The leader of the Trianomans is William of Glyme- charismatic, sophisticated, and prone to rumors of womanizing.
