Maranyuss

Maranyuss is a Night hag who was personally kicked out of Hell by Asmodeus himself. She found herself in Waterdeep and set up a bookshop called Curious Pages that specializes in esoteric books. At some point she met the deva Jinnaoth Ir'Gadohn and since they both hated Asmodeus, they entered into an uneasy alliance. Mara helped Jinn stop the ritual of the First Flensing which would have allowed Asmodeus to enter Waterdeep.

Appearance
Mara normally wears an illusion of beauty which makes her appear as a dark haired woman. In her natural form she is a hideous purple hag.
