One of the things I have applied to Nailah as she is a very newbie thraumaturge in training, is an aspect of instability. As far as I gathered, to get good at thraumaturgy the caster needs to have their emotional state in check otherwise they'll loose control of their spells.
So what I did with Nailah, because she has anger issues.. (She -is- a redhead afterall) is that whenever she gets angry she can't control her aether, and then random fireballs might happen. Currently I don't have her dependent on the active use of a staff/gem/thing to channel it through because I haven't been to certain on it. I would maybe tentatively make it so that she's carrying around a gem that aids her, if I had to put something in and I was allowed a little wiggle-room. It's caused some fun situations with friendly fire and made here more adamant not to loose her cool, and she did also once sear some of her hair off so she had to go short-haired for a while.
I don't actually remember where exactly I have it from (this is really typical of me, I read something and then I forget where I read it), if it's mentioned in any of the lore at all. It does seem like a sensible thing though.
