I like the idea of Mages or Seers of Void going through a whole self-realized Socratic Ignorance arc, like an "All I know is that I know nothing" kind of thing? Perhaps some starting out as insufferable know-it-alls, only to eventually be humbled by the Void aspect, and accept that it's alright not to know all the answers. This doesn't apply to all of them, of course, but I feel it would make an interesting character idea.

Oooh that’s a cool idea.
