Water Surface

Water Surface is a small area that can be reached from the Dark Staircase.

Overview
This area has a blue cloudy sky, with the floor reflecting it. Continuing through will be utility poles, and a red mailbox at the end of the path. Towers can also be seen from the distance. Interacting with the mailbox will take you to the Umbilical Cord Maze.

Trying to return to the Dark Staircase will instead lead to a small, empty room.
