Diminutive, supernatural creatures of legend that often appear as fairy-like beings, sprites have occasionally been seen carelessly flittering about Dr. Strange's Sanctum Sanctorum.
On one occasion, their presence accidentally alerted Dr. Strange to the presence of Wolverine, mind-controlled by the Undying Ones, when the X-Man absent-mindedly slapped aside a sprite that had been flying in his away. After Strange defeated Wolverine and freed him from possession, Clea saw to it that the sprite was not severely harmed..
Along with sprites, other small humanoid creatures of a mystical background have been seen gadding about the mansion's hallways, including inches-tall satyr-like and griffin-like beings. Whether or not these are also sprites but of different breeds is unclear..
