Below Penn Station and Madison Square Garden is a cavern that has been worn away by erosion and construction. This chamber is one of the junctions of the Underworld – a highly traveled spot, which connects several dozen major passage ways, and myriad minor ones. To get from one tunnel to another across this gaping expanse, the Underworlders placed a latticed web of rusting old steel girders from buildings all over town, crisscrossing the chamber at all levels, like some bizarre highway overpass.
The Underworlders refer to the area as Old Bones. It is a confusing tangle of pathways and girders, and even those Underworlders who know exactly where they are going sometimes find themselves lost after passing through the junction. It seems as though the area doesn’t conform to the rules of Euclidean geometry. Or, as some Underworlders say, “Sometimes, Old Bones sets you on the path that it wants to…whether you want it or not.”
