SCP-087 - "The Stairwell" / "The Infinite Staircase"

Welcome D-Class! Your goal is to get as far down SCP-087 as you can! Please keep the researchers informed about any anomalies, changes in scenery, or otherwise noteworthy occurrences. SCP-087 is a seemingly simple stairwell located on the campus of [REDACTED], with platforms often. However, researchers and D-Class have studied it and found that this SCP is seemingly infinite, with no tests ever feeling any closer to the bottom of the staircase.    Secure. Contain. Protect.
