Valsharess

For the word as a generic term, see Drow dictionary.

The Valsharess (meaning "queen" or "empress") was the name adopted by a female drow who gained great power and influence after finding out the true name of Mephistopheles, one of the Dukes of Hell, and using it to bind the devil in her service. She managed to conquer much of the Underdark and was in the process of going on to destroy Waterdeep before she was stopped. Unsurprisingly, it was the devil she had bound that was her doom; Mephistopheles fooled her into bringing into her presence a powerful adventurer who killed her and at the same time released Mephistopheles into Toril, which he subsequently threatened to conquer himself.
