Infinite Staircase

The Infinite Staircase is an extradimensional spiral staircase that connects the planes. An entrance to the Infinite Staircase usually appears as a nondescript door. Beyond the portal lies a small landing with an equally nondescript stairway leading up and down. The Infinite Staircase changes appearance as it climbs and descends, going from simple stairs of wood or stone to a chaotic jumble of stairs hanging in radiant space, where no two steps share the same gravitational orientation. It is said that one can find one’s heart’s desire on the Infinite Staircase through diligent searching of each landing.
Doors to the Infinite Staircase are often tucked away in dusty, half-forgotten places that no one frequents or pays any attention to. On any given plane, there can be multiple doors to the Infinite Staircase, though entrances aren’t common knowledge and are occasionally guarded by devas, sphinxes, yugoloths, and other powerful monsters.
