In a world known as the Ashen Wastes, an ancient civilization collapsed in an unknown "Great Cataclysm," leaving behind ruins stretching as far as the eye can see, mutated creatures, and "spirit remains" imbued with strange powers. The surviving races struggle to stay alive, while the "Ashen Wastes Walkers" are the explorers, warriors, and guardians of this age, unearthing, deciphering, and wielding the power of "spirit remains armaments."
