. . . () colossal shadow () that was not wrought by anything in the room. It filled the portals from side to side, it towered above the lintel – and then, swiftly, it became more than a shadow: it was a bulk of darkness, black and opaque, that somehow blinded the eyes with a strange dazzlement. It seemed to suck the flame from the red urns and fill the chamber with a chill of utter death and voidness. Its form was that of a worm-shapen column, huge as a dragon, its further coils still issuing from the gloom of the corridor; but it changed from moment to moment, swirling and spinning as if alive with the vortical energies of dark aeons. Briefly it took the semblance of some demoniac giant with eyeless head and limbless body; and then, leaping and spreading like smoky fire, it swept into the chamber.
