The Abyss Stalker evolved in the lightless depths where Creekside's waters run deepest and coldest. For centuries it remained dormant in underwater caverns, but recent construction disturbances awakened this ancient predator. Now it stalks the fog-shrouded waterways, drawn to surface by the same environmental changes that triggered the broader creature emergence.

The Abyss Stalker possesses pressure-resistant physiology that allows movement between deep water and surface environments. Its skin secretes a mucus that traps air bubbles, creating temporary oxygen reserves for extended surface hunting. Enhanced lateral line sensing enables it to detect vibrations through thick fog and murky water, making it an effective predator in zero visibility conditions. Rubber-like hide provides protection while maintaining flexibility for swift movement.

Serves as the apex predator of the emerging aquatic horrors, hunting both smaller creatures and creating direct threats to players navigating water-adjacent holes during the season's most intense fog conditions.
