Lolotte

Lolotte is the chief antagonist of Kings Quest IV: The Perils of Rosella, she is a powerful and evil fairy who seeks to spread evil across her realm in the manner of an evil witch or sorceress.

Lolotte stole the good fairy Genesta's talisman, which caused Genesta to rapidly lose her magical powers - so much so that if her talisman was not returned within 24 hours she would die. Genesta fears that Lolotte will use the talisman to unleash further evil on the magical land of Tamir and asks Rosella to aid in recovering the talisman in exchange for a magical fruit that can save Rosella's ailing father. Genesta disguises Rosella as a peasant girl in order to try and evade detection but Rosella is soon captured by Lolotte's goons and brought to the evil fairy's castle: Lolotte believes she is a spy and has her locked in a dungeon filled with skeletons and torture devices. Luckily for Rosella Lolotte's son, Edgar, is stricken by her and convinces his mother to set her free: in exchange she is forced to capture a unicorn for Lolotte to prove her "innocence".
