In the above charts there is no magical class that contains nothing from all of the elements (life, motion, and matter). I find this unsettling.
Now before we decide that it can't be magic because it doesn't contain those elements let us not forget that people from erfworld do not even know everything there is to know about magic, they debate about it. They do not know where stuff comes from. Perhaps it comes from nothing?
Also, since it wouldn't be tied to the elements it would almost be impossible to figure out, to cast, particularly if casters were looking for an element. Because they limit themselves to those elements it'd be almost as if it didn't exist. I suggest the only casters to master nothingmancy are the titans themselves.
With my previous theory that stuff comes from nothing, perhaps the titans created enough nothing in order to create enough stuff for a world. All worlds. Let's also say that for something to exist on such a scale there needs to be a lot of nothing. it would more or less explain why there's so much space between celestial bodies.

EDIT: I'll also note, if anyone hasn't, that Clevermancy and eyemancy use the same elements
