A series of events has transpired across the world of Norrath and the familiar faces of Firiona Vie and her nemesis Lanys TíVyl return to find themselves at the forefront of the events. Unbeknownst to them, a dark influence has seeped into the world of Norrath causing new tensions to arise and conflicts to intensify as the dawn of a new age emerges. The Age of War is upon the people of Norrath and heroes return in this ultimate, unending battle between good and evil.
Prepare for EverQuest: Dragons of Norrath and return to the lands between Halas and Lavastorm as you seek out the Nest, the ancestral birthplace of all dragons, long sealed away and hidden from the eyes of Norrath. But beware, if the Nest is exposed too early during the Brood Dawn, all dragons and their eggs will be cursed for eternity and death will storm down on all Norrathian's not in their service.
Featuring new lands with enhanced graphics, bold new storylines, and updated creatures including goblins, drakes and the ominous Frost Giant, EverQuest: Dragons of Norrath is the next great expansion pack for the fantasy saga that is EverQuest. Make ready with new features such as the interactive world map, use your potion belt to access magical items quickly, and quickly swap between weapon sets using the bandolier. Plus, with the all new guild hall you can easily get your guild ready to encounter anything that comes your way! EverQuest: Dragons of Norrath is bursting with new adventures and intense battles for players of all levels.
