Hrmm I had a concept for a faerie, was originally going to go with Goblins, but does anyone know any types of fae that are known for getting into pacts and bargains? Im looking to make a Faerie merchant.

Maybe they are just called "Pactmakers" or something, I have a definite idea in mind, but need to tie it better to some folklore creature (unless I can tie it to folklore itself, rather than a specific being from it)
