Hi Shaytan,
I admire your mod, game play and immersion at the best. The work of a genius!
Now what I suggest for ruler events, considering the specific flavor of the mod, is more events related to the flourishing of many religious thoughts of school and heresies. Surely in this reality, rulers must be trying to codify new religious synthesis, get into new heresies, have to deal with more courtiers secretly believing in the non-orthodox version of the state religion, deal with ulema / priests making unorthodox innovations, with mystic communities dwelling in the outskirts of the empires and threatenings stability or, in the contrary, providing soldiers of the faith... etc.
Hope that helps your creative process...
