For the first room:
Jutting from the walls are a series of steps, wide but precarious in their lack of a railing, circling the vast cylindrical compound.

New room:
Subaquatic observatory

A portal in the floor near the western edge of the spherical room yields the top of a precarious staircase. The apex of the underwater clockwork tower, this room is fashioned in the shape of a wide bubble. Though the floor is flat for ease of navigation, an paneled in bronze plates, the walls curve in a spherical fashion, crafted of thick, impenetrable glass, strong enough to withstand leagues and leagues of water pressure. The shape and composition of the glass allows for a clear, magnified view of the ocean--the vantage provides both a near-endless view of the floor, and the seemingly limitless surroundings above.
