The Lady of pain is the enigmatic and powerful entity that rules over the city of Sigil. While she may vaguely resemble a humanoid creature, she exists as something beyond the power or comprehension of Gods and mortals. She wears ornate robes that shroud her body and a crown of blades that surround her masklike face. No one knows who or what the Lady of Pain is or where she originally came from. She has the power to ban Gods and archfiends from entering the city of Sigil, and places a strict ban against any attempt to worship her. Worship of the Lady of Pain is a crime punishable by death by flaying or imprisonment in the Lady's Mazes.
The Lady of Pain also places a heavy emphasis on maintaining the city of Sigil's neutrality on many interdimensional conflicts such as the Blood War. The petty squabbles of the prime material plane are not allowed to touch the city of Sigil without the risk of inciting the ire of the Lady.
Occassionally, the Lady of Pain will float above the streets of Sigil, surveying the city. Any creature who dares to interrupt her path is flayed alive with the power of her glance or vanishes into nothingness.
While the Lady is a distant ruler and doesn't often involve herself with the daily goings on of the city of Sigil, the residents of the city view her with respect and fear, giving deference to her enigmatic power. The Lady has no residence and no temples to her exist within the city. Instead, the city is run by the many factions that make their home within the walls of the City of Doors.
