Lady of pain

The Lady of Pain is the most powerful entity in the Dungeons and Dragons (D&D): Planescape game setting, and possibly all of the D&D cosmology. She is only a lady in so far as she is characterized as female in her countenence. "The Lady" may as well be male or sexless, or such a type that traditional gender classification is impossible.

The Lady of Pain resides in the "City of Doors" called Sigil. Sigil sits at the philosophical center of mass of the most widely acceptee Dungeons and Dragons cosmology.

Seemingly more powerful than even the gods and powers in all the planes, the Lady of Pain rejects all forms of worship.
