The Underworld

The Underworld is one of the Realms of the Gods, the realm of Grenth, god of death. It is a very advanced gaming area and mobs are very strong there, so one is strongly advised not to go there without a party of eight experienced players.

Map

After entering the Underworld from The Temple of the Ages you will find yourself next to several ghosts (Gwen's mother Sarah, among others), of whom one will offer you the quest Clear the Chamber. It is recommended to first kill all monsters in the surrounding area before accepting this quest. As soon as you accept the quest several doors will open, allowing you to further explore the Underworld (after you have defeated the hordes of Grasping Darknesses that will swarm you as soon as the doors are opened).

The Underworld features several quests, which are quite demanding, but give tremendous rewards in experience points. These quests can be done repeatedly, once each time you enter the Underworld. All quests you have done on previous visits to the Underworld will be cleared once you leave it and you will have to do them again if you want to reach subsequent quests. In the Underworld rangers can charm the Black Widow Spider, after completing several quests.

You do not have a map available when venturing the Underworld, but a complete map can be found here @ GWonline.net.

The Underworld is the only place where you can find Storm Bows, Ghostly Staffs, Eternal Bows and Eternal Shields. Also Globs of Ectoplasm drop relatively often here.
