Fourth Door

The Fourth Door is one of four doors believed tied to the destruction of Aoskar in some way.  When it manifests every 500 years, it is located in the Lady's+Ward in Sigil in a structure known simply as the Tower.  The door is fashioned from heavy wood and has no knocker, handle or keyhole; it is covered with strange glyphs that cannot be deciphered, even with magic.
