|“||Composed of such innumerable ever-shifting interlocking chambers, the Underworld of Lord Hades all but guarantees the dead shall there remain until the end of time.||„|
There are six main rivers that are visible both in the living world and the Underworld. Only three of them appear in the game.
- The Styx is generally considered to be one of the most prominent and central rivers of the Underworld and is also the most widely known out of all the rivers. It's known as the river of hatred and is named after the goddess Styx. This river circles the Underworld seven times.
- The Archeron is the river of pain. It's the one that Charon, also known as the Ferryman, rows the dead over.
- The Lethe is the river of forgetfulness. It is often associated with the goddess Lethe, the goddess of forgetfulness and oblivion.
- The Phlegethon is the river of fire. This river leads to the depths of Tartarus.
- The Cocytus is the river of wailing.
- Oceanus is the river that encircles the world, and it marks the east edge of the Underworld.
Once a majestic temple dedicated to honoring all of the Cthonic Gods of the Underworld, in more recent years the temple has fallen into a state of disrepair. It is notable for being the only way in or out of the Underworld with Achilles mentioning that no other known entrance exists in the world.
The final resting place of the souls of the heroic and the virtuous in the Underworld.
The section of the Underworld where the souls of people who lived lives of equal good and evil rest.
The section of the Underworld where people who were evil during their lives are sent to face eternal punishment for their crimes after death.
A lavish estate located in the very heart of Tartarus. It is home to most of the Cthonic Gods and is also where all the newly deceased souls gather to be judged by Hades personally.
A dark forgotten corner of Tartarus which appears to be only accessible via an Infernal Gate, it is home to all of the mythological monsters whether evil, neutral or good who have been slain.
Notably the Minotaur Asterius was stated to have ended up in Erobos after his death before Theseus was able to convince Hades to allow him into Elysium.
Located even deeper then Tartarus itself, the strange realm which the primordial Chaos chooses to call home has long been a source of mystery and intrigue both among mortals and deities alike. Many have speculated what hidden secrets may lie within just waiting to be discovered, but very few have ever managed to successfully reach it to find out and even fewer have ever returned to tell exactly what it is they've found there.
All souls of deceased people and creatures go to the Underworld after they die. Most mortals who enter the Underworld after death, seem to appear primarily as Shades. However, there have been exceptions to this rule in the past. Great heroes such as Patroclus and Achilles are allowed to keep their bodies after death. Villains and other individuals have also been shown to keep their physical forms such as Sisyphus and Eurydice.
