Erebus is the first biome players will encounter within the Underworld region. Erebus features unique NPCs such as Arachne, a special NPC who can provide unique armor boons, Silver that can be harvested, and a challenging boss fight against Headmistress Hecate.


Oceanus is a biome in the Underworld, where the depths of Poseidon's domain merge with the ocean's abyss. It is the second accessible biome in the game, appearing after Erebus, and marks the second stage of Melinoë's descent toward Chronos. The Guardian of this biome is Scylla and the Sirens.


Fields of Mourning is the third biome of the Underworld, inhabited by Shades who have chosen to remain despite the encroachment of Chronos' forces. The Guardian of this biome is Infernal Beast.


Tartarus is a dark, maze-like biome located just outside the House of Hades. It is a grim prison, where the souls of those who committed sins in life are eternally confined. The Sands of Chrysos flow through the labyrinth, eventually spilling into a pool within the House of Hades. As the final biome Melinoë must traverse, Tartarus stands as the last obstacle before confronting Chronos.


City of Ephyra was once the capital of Thesprotia and a devoted center of worship for Hades and Persephone, but now lies in ruin. Ravaged by the armies of Chronos, much of its population was wiped out in the assault. Ephyra serves as the first surface biome that Melinoë must traverse on her journey to reach Mount Olympus. The Guardian of this biome is Polyphemus, the Infamous Cyclops.


Rift of Thessaly is a pivotal region on Melinoë's journey to Mount Olympus. It was formed by Poseidon, who flooded the land in an attempt to halt Chronos' forces from advancing toward Olympus. However, this strategy backfired, as the rift allowed Chronos' armies to travel more swiftly. With their fleet of undead warships, they now sail through the rift, hastening their reinforcements for the ongoing siege of Mount Olympus. The Guardian of this biome is Eris, Strife Incarnate.


Mount Olympus is the majestic home of the Olympian Gods and serves as the third and currently final biome of the Surface Path in Early Access. Unlike other biomes, Mount Olympus introduces a unique dynamic with its two distinct enemy factions: the forces of Chronos and the automaton defenders of Olympus. These factions are locked in constant conflict, with their attacks damaging one another as they battle for dominance. However, despite their infighting, both factions remain hostile toward you. The Guardian of this biome is Prometheus, Titan of Foresight.

The Summit is the peak of Mount Olympus, where the Pantheon, in which Zeus and the other gods live is situated at. At this location, you'll encounter Typhon and his monstrous children attempting to reach the Pantheon to snuff out the gods once and for all, but the gods will not go down without a fight. Zeus is still on this mountain, and he will defend his family with all his godly strength.
