Oh god the Black Death and a Orthodox Protestant Movement. Rebellions and defeats on two fronts. Proper Roman Lands and Citizens under Foreign yokes. This topped the last chapter and all of my expectations. This is the time to reform the Imperium and accept this Dark Age to prepare for the Great Crusade with the (reformed) Sisters of Battle (nice touch on using a WH40K loyal faction as a heretic btw), The Inquisition, reformed Cataphracts, and potentially more.
