The Waterspring Field of Tanaris was named so because of the many water towers which pump the life-giving liquid from reserves deep underground. However, since the cataclysm the entire field has been flooded from the South Seas.
The towers were built by the goblins of Gadgetzan in an attempt to provide water for their desert operations. However, these intentions were botched when a large group of nomadic bandits calling themselves the Wastewanders strolled in and claimed the field for themselves, selfishly hijacking the water towers in the process. The bandits now squat on the land hoping against hope that this home will be better than that one ogre camp. They still get the shivers thinking about it.
