The chain reels in slowly...even slower once it seems something is pulling against the other end. Within minutes...

You all rush to inspect the damage, and it's just as Staph predicted. The polyp is in charred hunks. The only damage to the room is a layer of soot.

The worm, amazingly, is in one piece, but shrunken and cooked like a piece of jerky. It still scoots across the floor as the distant Grindworm mindlessly devours the chain. You hope it will enjoy the surprise at the end.

That little creature follows you in, apparently having been smart enough to clear out during the blast.
