The great multi-planar hub, the City of Sigil, also the City of Secrets/Doors [Each slot had a narrow pamphlet with information about different restaurants and attractions in the city ('Annual Autumn Cheese Event! Multi-planar Cheese of Death Competition! Must Register by Midsummer!'), as well as guides on how to get along with the locals ('No Gods Allowed: How Worship of the Lady Can Lead to Your Skin Being Flayed Off'). There was also the very direct 'Get Along or Else', which had a shadowy image of a robed woman surrounded by swords, looming over a city street.]
