Hades' Palace

Hades' Palace is the home of Hades and Persephone (half of the year for the latter), located in the pit of the Underworld.

Description
It is apparently modeled after the gods' palace on Mount Olympus, since he is not welcome there for the most of the year. A person can only reach the palace if Hades wants so. If he doesn't, the person will just keep walking for eternity without ever reaching it. Perseus spent a great time on its dorrs, only being freed by Heracles. In front of it is Persephone's garden, it has been said to be the most beautiful garden on Earth.

Rooms

 * The Throne Room – Hades sits upon a black onyx throne made of skulls, surrounded by dead U.S. revolutionary soldiers, British Redcoats, Greek Warriors, Roman Legionnaires, Modern U.S. soldiers, and Confederate soldiers (as security). He is also surrounded by hellhounds and many undead warriors.

The Lightning Thief
Percy, Annabeth, and Grover come to diplomatically ask Hades to give them Zeus' stolen lightning bolt. Hades is found sitting on his throne, facing away from the three heroes.



The Last Olympian
When Percy Jackson goes to the Underworld with Nico di Angelo to bathe in the River Styx. Nico reveals that he had tricked Percy to get information from Nico's past. He hands Percy over to the Furies, who take Percy to the dungeon, a place below the palace. The dungeon is guarded by ghostly warriors and other dead. Percy is held here for a short time until Nico shows up and offers help. Percy accepts and the two escape to the River Styx.
