The Lower City is the gathering place for many of the refugees who fled from the war, including Arakkoa, Sporelings, and almost every other Outland race.
The Lower City
The Lower City of Shattrath is the place where the refugees gather and help out in their own ways. When someone helps any of the mixture of races who fled from war, word gets around quickly. Their quartermaster, Nakodu, is located at the market in the Lower City. The Lower City of Shattrath also contains a very useful Mana Loom or an Alchemy Lab. Many NPCs have extensive knowledge of crafting. The Battlemasters for both sides of all four battlegrounds can also be found here, as well as the World's End Tavern.
It also has a large number of useful NPCs and items:
An Alchemy Lab next to the Alchemy trainer, who also gives the [70] Master of Elixirs specialization quest for alchemists. Warlocks should note that this lab CANNOT be used instead of the one in Scholomance for the Dreadsteed quest.
Three tailors who allow you learn tailoring specializations, and buy new epic tailoring recipes for armor sets and special bags [including 20 slot bags].
Players aiming for faction higher than Honored should wait until honored to complete lower city quests. Run Auchenai Crypts, Sethekk Halls, and Shadow Labyrinth, and complete the repeatable quest [65] More Feathers. This quest rewards random common, uncommon and/or rare items in addition to rep.
If no instance runs are done it will take 1080 feathers to get from zero to Honored
Griftah, a vendor in Lower City, sells amulets which are very... interesting. He is quite the salesman, with items like Marvelous Madstone of Immortality, which allows you to return to life as long as you return to the place you died. Buyer beware!
At exalted you can purchase a Lower City Tabard. Strangely, none of the NPCs in Lower City can be seen wearing one.
Patch Changes
