Selene, The Witchlight

Time to get spooky. Selene, crafter of magics, expert blood ritualist, and soul binder all of which she operates in secret. You need to buy something specific from Selene and her shop The Witchlight can sell it to you, for a price. Selene takes payment in almost all forms just be careful when making promises. Words are binding.

I leave the specifics of the item you are going to buy up to you. Good luck.

Also vore because yeah she might eat you. You don't have to get eaten but it's an option. Plenty of other activities are available.
