Special Areas: Underworld and the Fissure of Woe

The Underworld is accessible through the Voice of Grenth and the Fissure of Woe is accessible through the Champion of Balthazar. These explorable areas remain closed until your region earns the Favor of the Gods. For example, if you play in the American region, and Europe has favor, you can't get in to these areas.

Kneel at the Statue of Grenth to summon his avatar. Offer him gold, and he'll allow your entire party to enter the Underworld. To enter the Fissure of Woe, kneel at the Statue of Balthazar to summon his avatar and appease him with gold. Find these statues in the Temple of Ages (Prophecies), Zin Ku Corridor (Factions), and Chantry of Secrets (Nightfall). http://www.guildwars.com/gameplay/pvp/favorofthegods.php
