Take down 10 Wastewander Bandits and Thieves east of Gadgetzan, then report back to Chief Engineer Bilgewhizzle.
You there! It's time for you to be a big helper to the Gadgetzan Water Company.
The Wastewander nomads out in the Tanaris desert have seized almost all the water wells! Without access to them, our water supply will dry up in no time. If you want to get in our good graces, then you'll help us bring justice to those nomads!
Head east of here and bring down ten Wastewander Bandits and Thieves, then report back to me on the double. Justice waits for no man... goblin... bah, just get on it!
