The Alliance and Horde fight valiantly to claim ownership of the Gulch and for what you may ask? Is it the strategic military location? No. Is it the strength of the timber garnered from the trees growing in the Ashenvale forest? No. Is it for the delicious gooey spider legs? No again.
The land in Warsong Gulch offers a mystery, should one side ever gain control they would have the opportunity to research a very strange phenomenon in the very rocks themselves!
The laws if Azerothean physics are suspended in this location, spells and arrows may pass unimpeded through the rocks and earth of this region! Truly a natural marvel of Azeroth itself. Whichever side holds Warsong Gultch long enough to unravel this mystery could rule Azeroth!
