Nexus (instance)



The Nexus is a dungeon in Northrend contained in the World of Warcraft: Wrath of the Lich King expansion. To enter the instance before level 77 players must first do a quest line for a red dragon who then flies you to the entrance. The dungeon layout is very open. You can go into different "wings", but the final boss, Keristrasza, a captured red dragon, can only be freed from her ice prison when you kill the previous three bosses.

The overall area is composed of:
 * The Nexus (Ice Caverns) for level 71-73 players
 * The Oculus (Magical Rings) for level 80 players
 * The Eye of Eternity, featuring Malygos as the final and only boss

Geography
To get there, you need to ride to Amber Ledge in northwestern Borean Tundra. A dragon will then fly you over to Coldarra. The entrance to the dungeon is somewhat hidden at the bottom of the rifts in the middle of Coldarra. Just go down, and when you see the Arcane Serpents, you are there.

Dragonwrath, Tarecgosa's Rest
A special version of the Nexus exists for players on the quest to obtain Dragonwrath, Tarecgosa's Rest.

Dungeon Journal
''In order to reestablish his dominance over magic, the blue Dragon Aspect, Malygos, has launched a ruthless campaign to sever the link between mortals and the arcane energies coursing through Azeroth. To this end, his blue dragonflight is redirecting the ley lines of the world to the Nexus, Malygos' towering lair.''
