The Lady of Pain is the fictional protector of the city of Sigil in the Planescape campaign setting of the Dungeons & Dragons roleplaying game. She is also known as Her Serenity, for the permanently vacant expression on her face, Her Dread Majesty, The Bladed Queen, or simply The Lady. She is only a lady insofar as she is characterized as female in her countenance. In the second edition AD&D Planescape setting, the Lady may as well have been male or sexless, or such a type that traditional gender classification is impossible. In the third edition rules for D&D, however, the Lady of Pain is listed as a lawful neutral female of an unknown race.
