The Harpers' Read

The hydra's terror is its heads — count them, for each one bites on its own, and woe to the warrior who tries to walk past that thicket of necks, for every head will snap at him as he goes. Hacking them off feels like progress and is a trap: a severed neck regrows, and worse, sprouts double, so that a careless butcher only makes the monster deadlier. The only honest way to take a head for good is to burn the stump shut — a torch, a flask of oil, a pixie of hellfire, anything that cauterises. Better still, forget the heads entirely and pour fire and raw destructive magic into the body until the whole thrashing mass goes still. Keep it off your decks if you can; in close quarters it will chew through your crew before you fell it.

Encounters of Record

• Session 50 — A six-headed hydra heaved itself aboard Deez Nuts' longship and killed a sailor before the company learned to cauterise its stumps with hellfire; Shade finished it with a chromatic orb.
