Two cabals that have some compatible interests, such as Nexus and Scion, could fight over who is the dominant partner in their alliance. Maybe as long as Nexus has Scion's cabal item, then Scions only get access to their cabal powers (including the power to recruit new Scions) as long as the Nexus leader allows it. However, this also puts Scion leaders in the line up for potentially becoming the next Nexus leader. In the meantime, Scions could attempt a coup to get their item back, and maybe they'll even get the Nexus item while they are at it.

This creates broader organizations on an as needed basis. The smaller a cabal is, the easier they are to conquer and keep under control.

Furthermore, I think Seantryn Modan must be destroyed.
