Yet suppose further. Suppose that all worlds, all universes, met at a single nexus, a single pylon, a Tower. And within it, a stairway, perhaps rising to the Godhead itself. Would you dare climb to the top, gunslinger? Could it be that somewhere above all of endless reality, there exists a room?...' You dare not.' And in the gunslinger's mind, those words echoed: You dare not.
