The Consortium is a faction you meet during your travels in Outland, your first contact with them will probably be buy wow gold within Auchindoun’s Mana-Tombs, or at Nagrand when you meet the Consortium camp at Aeris’s Landing. Led by Nexus-Prince Hamaad, this optional faction is full of smugglers and inter-dimensional beings called ‘Ethereals’, and are only concerned with making profit off of the planets they visit. You will be able to get friendly or better with them should you help them with repeatable quests, or alternatively, clearing the Mana Tombs in Heroic setting!

The Consortium’s leader is right outside the Mana-Tombs, but, in order to undertake most of the quests helping you gain reputation with them you will need to quest for the NPCs in Aeris’s Landing in Nagrand, or the Domes in Netherstorm. Their Quartermaster is also in the Stormspire at Netherstorm should you want to look at what you will be able to buy as you advance in reputation with them.

There’s a lot of one-time quests you may do for the Consortium, however, you will need to grind either Ogres for their beads or Zaxxis Ethereals for their badges, at above honored should you want to do it by yourself.

Neutral to Friendly

The best way to get to friendly is to turn in 10 Oshu’gun Crystal Fragments or 3 Pairs of Ivory Tusks at Aeris’s Landing as soon as you can, at 250 reputation per turn-in, you will be getting to Friendly soon, and can save your reputation gains from quests for over Friendly. Alternatively, if you don’t want to grind this much early on, you can run Mana-Tombs and complete the quests the Consortium has for you right outside of them for a quick boost.
