Mazmezz, The Creeping Queen, Lord of Vermin, Ex-Qlippoth Lord. The Demon Lord of Vermin goes by many names.
With how much she adores the attention of mortals, do you think Mazmezz would make a mortal herald (As Per Mythic Rules)? How would she go about gracing such power to a mortal and what even kind of agenda would she likely set them on?
Further more, what would be some potential artifacts of Mazmezz? What potent divine devices lost to history would be befitting of The Creeping Queen?
There's a little bit about her in Giantslayer book 3 (spoilers)
