Deepholm is one of the four regions of the Elemental Plane. It serves as both home and prison for the earth elementals, ruled by Therazane the Stonemother. Her faction,Therazane, is similar to The Sons of Hodir--players will need to unlock the pool of (daily) quests in order to purchase shoulder enchants. Besides Therazane and her elementals, the Earthen Ring has also made Deepholm its temporary home. Stationed in the Temple of Earth, they are attempting to mend the wound Deathwing opened.
Aeonaxx is a rare spawn in Deepholm that drops Reins of the Phosphorescent Stone Drake.
Major Quest Hubs:
Players start off at the Temple of Earth in the center. They are then tasked with finding three damaged pillar fragments, in different corners of the map, culminating with unlocking Therazane's Throne to the north.
There are no flight points in this zone.
Deepholm is the level 82-83 levelling zone of Cataclysm. Breadcrumbs to Deepholm first send players to the Earthen Ring earthshrines just outside Stormwind City and Orgrimmar. During The Maelstrom, players take a portal to see Thrall in the Maelstrom. Players are then dropped off at the Temple of Earth in Deepholm to start the long process of recovering the three World Pillar fragments.
Deepholm is a lightly-phased directed questing experience. The zone plays out as one long quest chain circling around the zone and winding up with a climax back at the Temple of Earth. At that point, optional daily quests open up with the Therazane faction.
After Deepholm comes Uldum, starting in the Temple of Earth with some foreshadowing quests at the Twilight Terrace.
