Teela Na, the current Sorceress of Castle Grayskull in the Masters of the Universe franchise, is the guardian of the secret powers held in Castle Grayskull. She was the Eternian who gave Prince Adam the Sword of Power that enables him to transform into He-Man and protect Castle Grayskull's secrets from Skeletor and his henchmen; she is one of only three characters (the other two being Duncan/Man-At-Arms and Orko) who secretly know Adam/He-Man's dual identity. She is also the mother of Teela, whom she entrusted to Man-At-Arms to raise as his foster daughter (although the 2002 TV show implies that he is Teela's biological father).
