Dark Tower of Rassilon (with Metallic Corridor Component)

The Dark Tower of Rassilon encompasses both the external tower structure (jagged obsidian spire with a spiraling staircase) and its internal metallic corridors, including the Metallic Corridor Dead Space. The tower is a Gallifreyan relic with psychological weight, but it is not purely symbolic—the metallic corridors form its functional 'vein of forgotten steel', through which characters physically navigate. The spiraling staircase may connect to the metallic corridors spatially, with the corridor acting as the 'cold metal' structure mentioned in the tower's description. The internal and external components are inseparable in narrative function: the corridors serve as the tower's physical interaction space, while the tower itself provides the ominous backdrop.
