Existence itself for starters.
But for a few others, the fact that some dimensions can have varying laws of reality, knowing how to establish yourself as a dimensional entity, and the dynamics of different factions on a dimensional scale.
There are more that don't immediately come to mind, but either way you'll have to deal with most of the needlessly complicated things existence has in store.

Why are things like that?
