So my

Depressive runs a speciality tea and herb store. He sells teas, mushrooms, herbs, and spices from all over the world - and from his native England - but tea is his passion. He's also an earth/plant aligned mage and sells supplies to other magic users with earth, plant, or crystal specialties. But he also as a secret contract with some Unseelie fae, the each-uisge, who trade him addictive starweed in exchange for human flesh, which he obtains by poisoning annoying customers.

Here's his wishlist. Is there anything else that would fit his TC that I've missed?

my pet

Agaricus has a few mushrooms I don't see in his TC on WL : )

Any of these? I crossed into spices more than herbs I guess, but maybe something will call to you.

Hmm... my pet

Olie has some crystals that may be useful?

Thank you for the suggestions! :3 I should have more than enough to satisfy even the pickiest customer, here.
