History
The Black Mire was farmland once, low fields that fed the Second Kindred's northern holdings. The Sundering didn't burn it — it drowned it, the water table rising overnight with something that was no longer quite water. What grew back grew back wrong: bloated reeds, trees that breathe fog, and the Mire Hydra, a thing with too many necks for anything that used to live in a farming province. Wardens still map its edges every season, because the swamp itself seems to be spreading, a slow inch further into Eldenwood every year.
Boss — the Mire Hydra

Finds you while you hunt here: every hunt in this region has a 2% chance to be the boss instead of a regular monster. No key needed — see the Bosses page for what it drops.
