Hag of the Vast Swamp
Much like the Bog Hag from the Monster Manual, except with stringy black hair, braided with bones of old enemies. This hag carries many nature and heal rituals, and the necessary components along with a few magic items.
Belguza is well beyond her prime, but she still has enough reputation in the swamp that the other creatures do not bother her. She is able to run a successful business, as long as she stays out of the affairs of the other denizens of the swamp.
