Not much is known about High Priestess Vennabyll. Her dark skin and priestly robes appear very Tahaadi in origin, yet her accent sounds more northern than anything else. She dwells within a temple constructed of pure gold, protected by golden guardians that may or may not be alive.
She seems to have a connection with the long extinct race called the Barley Doos, as the Barley Doo sigil appears on the door of her temple as well as throughout the temple interior. Her motivations are currently unknown.
