The Icecrown Glacier region is now open in World of Warcraft: Wrath of the Lich King beta build 8926. The gates in Dragonblight have had a world event that changed the area. The whole area surrounding the gates are now ablaze; and both Horde and Alliance NPCs are fleeing in horror. You can listen screams in real time and NPCs fleeing. At the front of the Icecrown Glacier gate is now no other than Queen Alexstrasza and Korialstrasz (Krasus) in dragon form.
The Icecrown Glacier region is just huge. The architecture of various Undead Scourge buildings are a mix between gothic and bizarre made of Saronite metal ore. These saronite metal is said to come from the Old god Yogg-Saron (Forgotten One) that King Arthas had defeated in Warcraft 3: Frozen Throne (Read the map campaign transcript). Same as Magtheridon, the Forgotten One did not die. Arthas the Lich King has kept him imprisoned to be the Undead Scourge’s saronite ore resource.
These are the biggest buildings ever in World of Warcraft found everywhere in Icecrown Glacier. Even the gates and bridges are gigantic. The Onslaught (formerly Scarlet Crusade) are now following Archbishop Landgren, servant of the Lich King. Their base of operations is an isle to the west: Onslaught Harbor. It holds a huge cathedral and their main fleet port.
On the far northeast is the Sindragosa’s Fall area, from where Arthas the Lich King rose the Frostwyrm Sindragosa back to life in the cinematic shown at Leipzig GC 2008. The main hub of quests for Alliance and Horde is a bit hard to spot. The quest hub is aboard huge flying platforms … think of Marvel Comics S.H.I.E.L.D. Hellicarrier. There is a strong presence of Vykrul villages at the center and western coast of Icecrown Glacier. Watch the video below.
