The description of the game, as per "GoGamer:"
"Overview - Welcome to Sigil, the City of Doors, a place with gates that lead anywhere in existence provided you have the proper key. It is a neutral ground and watering hole for races across the multiverse, all under the watchful shadow of the Lady of Pain, the enigmatic ruler of the city. It is a place where the word is mightier than the sword, where thought defines reality, and where belief has the power to reshape worlds and change the laws of physics."
