Abyssal Echo of the Lost Voyager

The creature is a spectral remnant of a mariner who was lost to an infinite abyss. Drifting through the world in search of belonging, it emits mournful echoes that reflect the fear and despair of all who hear them. Its translucent form flickers with an eerie luminescence, revealing glimpses of the shipwreck that claimed its life. The echo resonates with the sorrow of countless voyages, engaging its foes by tapping into their own regrets and fears. When it strikes, it layers psychic energy over physical blows, manifesting the lost memories of its victim and drawing them closer to their own demise.
