I'd like the ability to tie summons (such as Ermor Ashen Empire) and other spells/abilities (such as LA R'lyeh's insanity ability and C'Tis Miasma effect) to Dominion

To get specific for my own uses: Dominion that creates carrion-beings and Dominion that creates the weird critters you get when you use cross-breeding. Maybe even Dominion that gives you different kinds of animals.

Along these same lines, I'd like to be able to create a spell that summoned one of several different creatures, so as to create this kind of spell-I'd like to do a couple of demon ones, sometime.
