The Nexus, a dungeon hub, is an ancient ice fortress found in the center of Coldarra, in Northrend's Borean Tundra. It is a column of magical energy surrounded by levitating earth-covered rings with ice caves underneath. The Nexus is an extensive series of caves and tunnels that riddles Coldarra, containing wings leading to two 5 man dungeons and one 25 man raid.

The Eye of Eternity is the final instance and the only raid of The Nexus, in which players will be able to defeat the blue dragon aspect Malygos.
