The Nexus added to the official Wrath page
A little earlier today, Blizzard has made a new addition to the official Wrath of the Lich King site. They've added The Nexus to the dungeons listing! The Nexus seems to be made up of three wings. The Nexus and The Oculus will be 5 man dungeons, and there will also be a 10 and 25 man raid zone that seems to be currently unnamed. It, most likely, houses Malygos himself.
The description of the zone gives a little more insight into the situation between Malygos and the Kirin Tor, and tells us of something called the Arcanomicon. It is a map of Azeroth's ley lines, which the Blue Dragonflight is using to redirect magic away from those he believes are abusing it. The Nexus will be found in the Borean Tundra, one of the first zones in Wrath of the Lich King. I expect one of the five mans will accompany one of Utgarde Keep's wings as the 'first' dungeons of Wrath.
