Mana Tombs was a fair instance. Better than Crypts and Sethekk at least. Not quite on par with Shadow Lab. The Ethereals were the main race inside, which is nice because I liked them a lot. But the instance had a lot of trash. And a couple of really tough bosses. (The Shadow Boss and Prince come to mind.) They could be rough on Heroic setting. I remember the loot being decent and quest rewards were not too shabby also. But someone ALWAYS started the escort by accident.

I give it a 2/5. Theoretical 3/5 if everyone has done the escort previously, or noone screws it up.

Auchindoun is a former draenei holy site and Horde fortress in the middle of the Bone Wastes, in Outland's Terokkar Forest. It was a holy ground for draenei burial until the Shadow Council took over, summoned an extremely powerful demon as old as time itself, and destroyed half of Terokkar Forest in the process. Different factions now vie for power in this magical spot: Ethereals suck the arcane energy from the Mana-Tombs, the Burning Legion harvests souls inside the Auchenai Crypts, arakkoa zealots work dark magic in the Sethekk Halls, and the Shadow Council plots its domination of Outland from within the Shadow Labyrinth.

Its inhabitants are mostly ethereals opposing the Consortium. The Mana-Tombs provide reputation for the Consortium until Honored; afterwards, in order to gain rep with the Consortium in Mana-Tombs, it must be run on Heroic (which requires honored with Lower City). The ethereals of the Consortium cannot enter due to the anti-ethereal wards set by Nexus-Prince Shaffar; they have attempted to breach the gates with little success, but have still tested whether or not their efforts worked - often resulting in the spotaneous combustion (for lack of a better term) of the ethereal tester sent through the gate. According to the Consortium, the ethereals in the Mana-Tombs are robbing it blind and if you wish to do business with them, you'll have to aid in taking out the competition.
