It was in geosynchronous orbit with Moloch, connected by a single trisilicate fibre called the Bridge. A toroidal space elevator called the Lift moved along the Bridge with the fluctuations of Lucifer's magnetic field to generate power. The Pit passed straight through the centre, with Eden's Belial Base on one side and the Bridge terminus on the other. A path spiralled around the Pit, and when someone slid down it, they were somehow turned around at the centre of the moon. Branching off the Pit were hundreds of tunnels filled with strange artefacts and machinery. In the centre was the Mushroom Farm, housing the controls for the system. The two moons worked together to modify morphic fields. This technology was constructed by the Angels millions of years before the humans arrived.
