Could someone help a clueless newbie?

I just got this game a few days ago, and I absolutely love it. It has to be one of the most varied strategy games I have ever played. The problem is I'm in the dark about some of the most basic features.

I'm currently in my second game of any real length(the first one as R'yleh ended with every priest and wizard I made going crazy or getting killed by vastnesses or horrors in the void gate) as the Mictlan, with a turmoil and luck heavy dominion for lots of good random events. Well, one of the events I keep getting is fanatics joining the cause While I appreciate the help I'd rather it come from something other than worthless militia that are just sucking up gold and supply and whose morale sucks bad enough that even sending them off to die doesn't work since they break at the first sign of combat. Is there a disband command? I can't find it anywhere in the instruction manual keyboard shortcuts.

Also, since I'm relying heavily on blood and death magic should I be worrying about potentially summoning things that are going to fight me instead of the enemy, like with R'yleh? I'm not far enough into the late level spells to worry yet I think, but it is something I'd like to avoid getting burned on again. Though the possibility of being able to use a horror that was able to tear my pretender to shreds sure seems nice.

Anyway, these are my most pressing questions for now. Thanks for any help you can give!
