Since I'm not sure if either of the Dark Ones will offer for the masses-- This sort of witchcraft isn't usually my specialty, but it's a fairly simple spell where I come from and it's called a locator potion. I can concoct it so that it finds a specific soul rather than a body. I'd just need an artifact or two belonging to the person whose soul you want to find. No charge, but I thought I'd offer to those going out hunting.
I'll be at the bakery setting up shop there
because my condo is very cold and just ask for Elsa.
