A massive shape rises slowly from the water's surface, larger than any creature you had thought possible. The leech-like face has three inky black eyes stacked above a jawless mouth filled with serrated teeth. Long tentacles, lined with barbs, detach and uncoil from its body—one, longer than the rest, ends in a fish tail. It navigates through the waters effortlessly and lowers its gaze to look directly into your eyes, overwhelming you with its ancient presence.
