Dire Maul

Dire Maul is a three-wing instance found in northcentral Feralas. It was once a proud Highborne city called Eldre'Thalas, but now lies in ruins, overrun by ogres, satyrs, and undead. Only a tiny remnant of the original Highborne population remains in the form of a murderous sect called the Shen'dralar. The enemy level range is 36 to 47.

History
From Blizzard's Official World Dungeons site:
 * Built twelve thousand years ago by a covert sect of night elf sorcerers, the ancient city of Eldre'Thalas was used to protect Queen Azshara's most prized arcane secrets. Though it was ravaged by the Great Sundering of the world, much of the wondrous city still stands as the imposing Dire Maul. The ruins' three distinct districts have been overrun by all manner of creatures — especially the spectral Highborne, foul satyr and brutish ogres. Only the most daring party of adventurers can enter this broken city and face the ancient evils locked within its ancient vaults.

In World of Warcraft: The Comic, Dire Maul is featured prominently as the location of the Crimson Ring's annual championship gladiator matches. The gladiatorial games begins with individual single combat matches and which ever gladiator team can survive the individual trials intact can advance to team combat matches to vie for the team championship. It is presumed that members of the teams who were unable to advance to team combat matches continue to fight in single combat matches to vie for the single combat championship(such as Bloodeye Redfist).Rehgar Earthfury's team, consisting of an amnesic Varian Wrynn, Broll Bearmantle, and Valeera Sanguinar, claimed victory over the previous year's team champions: Giago, Two-Heads, and Brlee (members of the Gordunni Clan of Ancient Draenor).

Dungeon Journal
''Built thousands of years ago to house the kaldorei's arcane secrets, the formerly great city of Eldre'Thalas now lies in ruin, writhing with warped, twisted forces. Competing covens once fought for control of Dire Maul's corrupted energy, but they have since settled into uneasy truces, choosing to exploit the power within their own territories rather than continue to battle over the entire complex.''
