Don't remember if it was mentioned in this threat or another place but someone had a pretty awesome idea about how to merge the cabals. Could put the Empire and the Tribunals together, the Outlanders and Battle together with different groups, so that you have the wild-like ones who don't hate magic but don't trust it either since it's against nature, the Nexus and the Scion combined with the mages in the Outlanders to make the Masters of Magic again, and maybe throw in the Fortress's mages, but that's not that big of a deal, and the Fortress on its own against the evil people in all the other cabals.
