For example, Seanan is a Crusader primarily because historically he has primarily held leadership and defensive positions (pre-Helovia). However I also chose Practicioner at first because I just didn't think anything else fit. Now though I'm loving the choice because it's giving his character a lot of different ways to develop and it dove-tails nicely into his defender-protector mentality (not that he'll tell anyone that's a thing).

I think she might make a good Looter, who are people that put up riddles and try and steal things, basically XD Or maybe an Artificer? Maybe she likes to make physical things that last, even though her memory may not.
