The screams intensified, and overlapped each other, one scream drowning out the rest, then another scream drowning out that, until they were all but unrecognizable, a single mass of world-ending shrieks… And then a single shriek. Monstrous. Higher pitched than the Hobgoblin, and weaker, but in the same vein that it was.
The black mass bulged on one side, as something hit it. Then it bulged on another side, as something else slammed against it, in time with the shrieks. Then somewhere else, then another place, each location impossible to determine, each action done erratically.
The void on the floor slowly began to close, and with it, the black mass seemed to harden. It lost that liquid oily shine that it had had before. It didn't deform and reform quite so elastically when whatever was inside it hit it. The dents stayed, and stayed.
