Across Nine Realms shaped by ancient Norse cosmology, a celestial artifact known as the Monolith once maintained balance among all worlds and civilizations. Centuries of warfare and a foreboding prophecy have fractured this order, leaving the realms on the brink of collapse as an undead plague consumes everything in its path—a harbinger of apocalypse. Facing extinction, Aras, the Monolith's last guardian, frees an amnesiac prisoner from captivity and thrusts upon them an impossible mission: journey through decaying worlds and restore the Nexus Orbs that once powered the ancient construct. From frozen wastelands to overgrown forests and forgotten homelands, the prisoner must battle through hordes of undead corruption to prevent the final catastrophe.
