Welcome to Sigil, the City of Doors, a place with portals that lead anywhere in existence, as long as you have the right key. It is neutral ground and a hub for adventures across the multiverse, all under the watchful shadow of the Lady of Pain, the enigmatic ruler of the city. It is a place where words are more powerful than the sword, where thought shapes reality, and where faith has the power to reshape worlds and alter the laws of physics.
