Level 9223372036854775807 - The Escherian Stairwell, Escape The Backrooms Wiki

Safe No Sanity Risk Devoid of Entities Level 9223372036854775807, also known as The Escherian Stairwell, is seemingly an infinite stone staircase with openings where a white void can be seen. It is currently undetermined in size. Nobody has been able to reach the top, so it leads many to believe that it's infinite. Each level has a number corresponding to its floor number. All numbers change to infinity symbols past floor 99. It has been theorized that this is the deepest level in the Backrooms.
