Ooh, I think both those potential quests sound exciting. I edited my original post to make mention of the new Apothecary class that's specific to this campaign. I'll link it below if you're interested. Wizard would be great for quest "A Cure for All" but you might like Apothecary even more.

And I'm totally open to altering personal quests. What did you have in mind?
