Underworld

The Underworld, also referred to as "Hell" or to some people who don't want to say hell say Hades (Hades as the god, name means hell), is located under DOA ( Dead On Arrival) Recording Studios in Los Angeles, California, although in the movie it is located behind the Hollywood sign. It's where the souls of the dead go when they die. The Underworld is divided into various sections. The Judges of the Underworld decide where a soul should go based upon their life's accomplishments. In Greek times, a man named King Radamanthus judged the dead and was later joined by King Aeacus and King Minos.

Entrances
DOA Recording Studios The entrance is managed by Charon, the reaper of souls. He takes them into an elevator and heads down, where they sail across the River Styx toward the opposite shore. On that shore, Cerberus, a three-headed dog born from Echidna and Typhon stands guard. The souls must pass by Cerberus toward their afterlife. Once they pass Cerberus, they cannot leave.

Door of Orpheus
A lesser-known entrance, the Door of Orpheus, stands in Central Park, NY. Orpheus created it to retrieve the dead spirit of his wife, Eurydice. Music is required to open this door and Percy and Nico used it in The Last Olympian with Grover 's reed pipes. It lets out behind the main gates, therefore being more direct to Hades' palace.

River Styx
Charon's ferry floats along this river on it's way to the main gate. In ancient history, Achilles used the river to become invincible. Since the river is so powerful, the person bathing in it has to pick one vunerable spot on their body to make sure you are anchored to their human life, or else they will dissolve into the river. Thus the saying "Achilles' Heel" came to be because he was defeated in his vulnerable spot, his heel. There is also a place on the human heel that is called the "Achilles Tendon", mainly because that is what scientists discovered and named with Achilles.

Luke Castellan used the river to be able to host Kronos. His weakness was a small bit of skin just under his left arm.

Getting the idea from Nico di Angelo, Percy Jackson used the river to become invincible so he could defeat Kronos. His vulnerable point was in the small of his back.

Also, swearing on the River Styx is the most serious oath you can make.

Judgment Pavilion
Once a spirit enters the Underworld, it enters the Pavilion, where three spirits judge them and put them in a certain place, according to their actions during life. One of the three judges is known, King Minos. Annabeth mentions William Shakespeare and Thomas Jefferson being one of the judges. In Greek times, a man named King Radamanthus judged the dead and was later joined by King Aeacus and King Minos. Now there is a select group of judges that rotate regularly.

The Fields of Punishment
The Fields of Punishment are fields of complete and brutal torture for souls of people who have done extreme wrongs in their lifetime.


 * King Sisyphus cheated death numerous times with the first one having him chain up Thanatos so that no one can die. He even appealed to Persephone that his wife never gave him a proper funeral. Sisyphus was sentence to roll a boulder up a hill that would roll back down when it gets close to the top.


 * King Tantalus was invited to dine with the gods and was said to have stolen nectar and ambrosia and brought it back to his people alongside the secret of the gods. Tantalus later chopped up his son Pelops and served him as food to the Gods. Upon his death, his punishment was to stand in the middle of a lake under the branches of a fruit tree, but whenever he reached for the fruit, the branches would retreat from his grasp, and whenever he leaned down for a drink, the water would recede from him.


 * Ixion was the king of the Lapiths, the most ancient tribe of Thessaly. Ixion got mad at his father in law and ended up pushing him onto a bed of coal and woods, commiting the first kin-related murder. The prince's of other lands ordered that Ixion be denied of any sin cleansing. Zeus took pity on Ixion and invited him to a meal on Olympus. But when he saw Hera, he fell in love with her and did some under the table caressing until Zeus signaled him to stop. Zeus created a cloud-clone of Hera to test him and Ixion made love to her which resulted in the birth of Centauros who mated with some Magnesian mares on Mount Pelion engendering the race of Centaurs who are called the Ixionidae from their descent. Zeus ended up driving Ixion from Mount Olympus and then struck him with a thunderbolt. He was sentenced to eternity in the Fields of Punishment tied to a winged flaming wheel that was always spinning. Only when Orpheus came down to the Underworld to rescue Eurydice did it stop spinning because of the music Orpheus was playing.

It has "miles of barbed wire separating the different torture areas." Some of the torture areas include being burned at the stake, running through cactus patches naked, being chased by Hellhounds, and being forced to listen to opera music. It is also noted by Percy Jackson in the Lightning Thief that there was lots of people in the Fields of Punishment

The Fields of Asphodel
Souls who don't wish to be judged go the Asphodel Fields. According to Grover, it is described as "standing in a wheat field in Kansas for eternity." Annabeth Chase stated that most people don't do either good or bad in their lifetimes, thus floating in the Asphodel Fields forever.

Elysium


Elysium is the place of paradise for heroes. Those who die a hero's death live in peace in Elysium. Percy states that is where he wants to end up and it is where the demigod and ex-Hunter, Bianca di Angelo is now. Charles Beckendorf, Silena Beauregard, Lee Fletcher, Ethan Nakamura, and Luke Castellan are also there. In the middle of the lake, is the Isles of the Blest.

According to Percy, the only part of Elysium that can be seen behind its locked gate are several houses from different time periods. The grass ripples in rainbow colors and it is possible for one standing outside the gate to hear laughter and smell barbecue cooking.

Isles of the Blest
The Isles of Blest is reserved for heroes who have chosen to be reborn three times, each time achieving Elysium. Not many people live in the Isles of the Blest, and not many will, as there are not a lot of people who do good in their life, according to Percy Jackson. Luke Castellan, was one of the few heroes who wished to go into the Isles of the Blest, when he sacrificed himself in order to destroy Kronos. Annabeth instead, tells him that he always put too much stress on himself.

It is described as a glittering blue lake with three small islands like a vacation resort in the Bahamas.

Tartarus
Tartarus is the darkest and deepest area of the Underworld. Tartarus is where the gods imprison their enemies, chiefly the Titans. Kronos is known for being held there. When a monster is slain, its essence is sent to Tartarus until they can reform.

Tartarus is the lowest region of the world, as far below earth as earth is from heaven. Tartarus is described as a dank, gloomy pit, surrounded by a wall of bronze, and beyond that a three-fold layer of night. According to the Illiad, it is a 9-day anvil fall from the other regions of Hades.

The Fourth Age
Before the battle when Kronos ruled, he kept the Hekatonheires (Hundred-Handed Ones) and the 3 Cyclopes in Tartarus, guarded by Kampe.

The Fifth Age
Tartarus is where Kronos, along with some other Titans,was imprisoned after the battle between the Gods and the Titans. Their jailer were the Hekatonheires.

The River Lethe
The River Lethe is the River of Forgetfulness, and it is used on people who try for rebirth. It has pure black water and is seen in The Demigod Files. According to Annabeth, it is strong enough to wipe the mind of a Titan.

Hades' Palace


Hades' palace is where he lives and operates his command over the Underworld. His gate is engraved with images of death and his throne is made of bones, with a flowery throne next to it for his wife, Persephone. Hades built it to resemble Olympus even though everything is black and bronze and on Olympus, everything is silver and white.
