Epic quality set items. These can be obtained by turning in specific items gathered in Ahn'Qiraj to the dragons at the entrance of AQ40.

The sets for each class are:

Class	Armor Set
Druid	Genesis Raiment
Hunter	Striker's Garb
Mage	Enigma Vestments
Paladin	Avenger's Battlegear
Priest	Garments of the Oracle
Rogue	Deathdealer's Embrace
Shaman	Stormcaller's Garb
Warlock	Doomcaller's Attire
Warrior	Conqueror's Battlegear

Note: All armors of the same type seem to share the same art, differing only in color.

For more details, look at the individual sets.
