The Chelonate

"Waves lap the slabby sides of a vast turtle-shell - bigger than any cathedral. Chelonites loaf on wooden docks around the shell-sides, staring sullenly. Lamps hang like decorations in a festive butcher's window. All around you, the sea is rank with scraps of ancient flesh."

A rotting zee turtle monster corpse inhabited by crazed monster hunters. Despite it being located near the Gant Pole, where zee monsters go to die, the inhabitants are very quick to point out that their ancestors totally slew the monster they're living on, and the Gant Pole being nearby is just a coincidence. They will point this out with whatever weapons happen to be nearby.

As a rotting corpse, it does smell terrible.
