Deep-Water Lurker

Deep-Water Lurker
The Deep-Water Lurker is a massive and terrifying monstrosity that inhabit the unmapped trenches and submerged crystalline grottos beneath The Shrouded Boughs. These creatures appear to be a twisted fusion of a colossal squid and a predatory sea-serpent, with long, muscular tentacles and a maw filled with rows of needle-sharp teeth. They are the primary reason why even the most experienced Mist-Whisker sailors and scavengers avoid the deepest sections of the root-labyrinth.
Deep-Water Lurkers are intelligent and patient hunters. They use the total darkness of the deep sea to their advantage, waiting for the vibrations of a passing skiff or a diving Muridae to strike. They are said to be the "Keepers of the Abyss," guarding the pre-flood secrets buried on the ocean floor. While they rarely surface, they are capable of reaching into the shallower channels of Drift-Haven to snatch unsuspecting prey from the piers.
Secret Motivation: The lurkers are instinctively drawn to "Aetheric Sinks." They often position themselves near underwater energy-leaks, using their own massive bodies to "plug" the leak and feeding on the raw magical energy as it flows through them.
Adventure Hook: A Deep-Water Lurker has taken up residence in The Deep-Dive Grotto, preventing the Mist-Weaver Coven from performing their "Deep-Memory" rituals. High Shaman Kaelis hires the party to descend into the grotto and drive the creature back into the abyss.
