Who is the drow woman depicted on the cover of Waterdeep: Dungeon of the Mad Mage? Is it Vlonwelv Auvryndar, Erelal Freth, or someone else?
The book in question has only this to say (on page 2, On the Cover):
Cynthia Sheppard illustrates a host of villains vying for control of the dungeon's depths.
According to Dragon+, the artist herself has said:
The drow female is the closest to the real me. That’s my ‘judgment face’, with different hair and pointy ears.

Not sure how accurate it is, but Partial Arc refers to the character merely as "a drow queen". While I don't know if there is a drow queen in the adventure, fandom does refer to Vlonwelv as a princess.
