Annoyed by her inability to travel beyond the borders of her swamp, the witch Metallia makes a pact with the legendary Hound Knight to realize her dream of spreading her swamp across all of Medea.

As the Hound Knight, your mission is to do everything your mistress, the swamp witch, commands. Explore the world, destroy pillars that prevent her swamp from spreading, and unleash indiscriminate devastation. Yet, in the deepest corners of your eerie mind, you begin to wonder: What is stopping Metallia from leaving the swamp? Why do the other witches avoid her, and how can she survive in a swamp notorious for its toxic fumes? Is Metallia truly a witch deserving of respect, or is she one to be feared?.
