The Stairwell was a dimension consisting of various stairways with contradicting gravity.
Dawn Summers, Xander Harris, Bub, and Rancidus were in this dimension while travelling from Anharra in search for Earth, more specifically between the Dimension of Giant Shrimp and the Forest of Doom.
In this place, they weren't able to reach each other, and Dawn noted her powers were “useless” there. The confusing gravity and endless stairwells made Rancidus nauseous.
Behind the Scenes
- Dawn compared this dimension to M. C. Escher's print Relativity (1953).
