Hmm... both, indirectly. Faerie magic itself is somewhat newer to me, since I've only learned about it since coming here, but a lot of the infections and the like that I'm used to handling apparently read as magic in nature to a lot of people. Some of them would probably fall under 'weird poisons', too.

[So, neither but also both.]

Basically, the point is, finding cures to strange illnesses is something I know about.
