Umbra-Leviathan

Sailors tell of black tides that swallow whole brigantines and of a low keening that steals the will to row. Gravewardens mutter of 'shadow-whales' that gather where grief pools and feed on the fear of the living. Scholars debate whether Umbra-Leviathans are spawned by malevolent gods or by long-dead sorcerers who wove hunger into shadow.
