The Severed Floor
The windowless basement where innies live and work — MDR, O&D, and departments unknown.
Updated through S1
The severed floor is Lumon's subterranean maze of identical white corridors where innies spend their entire conscious existence. It houses Macrodata Refinement, Optics & Design, the goat department, the Perpetuity Wing and more — most of it hidden even from the people who work there.
What's confirmed in canon
S1MDR maps only a fraction of the floor; O&D, the goats and the Perpetuity Wing widen it.
S2The testing floor is revealed below, hidden even from the severed staff above.
Where the community lands
The floor is a world unto itself, and the show keeps revealing it is far larger than the four refiners know. Fans map its departments as clues to Lumon's true scope and mission.
