Home of the Dragons
Dragonblight is one of the many exciting zones in the upcoming Wrath of the Lich King (WotLK) expansion for the World of Warcraft (WoW). The zone is mainly a frozen wasteland that houses the dragon graveyard. While the zone has a lot of history and lore around it, however not much is known yet about what will take place there in WotLK.
Not much is know as of yet in regards to instances in the zone . It is possible that Wyrmrest Temple will be an instance, or the five temples surrounding it. However it has also been rumored that Naxxramas will be moved to the zone as a new level 80 10/25 man raid. This is due to the fact that at Blizzcon 2007 a large necropolis was shown floating over the terrain of Dragonblight. In addition Blizzard has repeatedly stated that Naxxramas will likely make a reappearance in the Wrath of the Lich King.
What we do know so far is explained by Byron "Messiah" Mudry in this overview of the zone: Dragonblight Overview
