u have to get afrodite's magical mirror and find Hercules to come and push the rock out of the way. the u just walk through the door and see hades.
Once Zeus has taken the 5 sacred items, Hercules will agree to help you, and will move the rocks blocking the way to Hades and to Poseidon. (You will need the Touchscreen Mirror from Aphrodite in Poseidon's realm.)
hades! the land of the dead
In the Underworld, realm of Hades.
herculees does that
To get in Hades realm you need pomegranates.
The underworld, the realm of the dead.
The entrance to the Underworld (realm of Hades) is in the Temple of Hades. Put pomegranates (from the garden of the Sphinx) on the altar to open the door. You cannot move the rock from the throne room. Only Hercules can do that, and not until you have collected the 5 sacred items and returned them to Athena at the Tree of Immortality.
On the far right of Hades' realm is Poseidon's realm. Place the starfish on the tray (if you have it) and he's in the realm. But you must later on in the game have Hercules break the rock blocking his thrown underwater. Their you would find Poseidon's.
throughout the game after zeus takes your items athena will talk to you and tell you to speak with hercules and he wil finally help you and he will move the rock from hades throne.
It is simply referred to as The Underworld.
You get all the items that Zues asked for. Then you find out that Zues was using you. then Athena tells you to get Hercluse to talk to move the rock and another rock. After you get Hercluse you go to Hades' relm. Hercluse crushes the boulder. Then go under the sea to were that rock is. Hercluse crushes it. Go into Posiedon's realm. Then go to Mount Olimpus. Light the lights. Fight Zues. Then you have beaten Mythology.
Hades likely enjoyed his realm the Underworld from the time he spent there.
