Yes, the politics would be one of the themes I would discuss with players. I've played with this group for a few years so I think they would enjoy that. I like the Tremere theme of 'doing the right thing for the wrong reason' and, in 5e, I play the Tremere house as looked upon warily but other magi in general know that if a deal with a Tremere mage is reached, they can seek recourse from House Tremere who will enforce the deal. Being so hierarchal, in my usual sagas, also means being a member of the House means the other magi view you as a representative of the House so House Tremere ensures its deals are followed. Right thing (honoring the deal), wrong reason (because it increases political capital) once again.
