Beneath the Double Rainbow is a subzone in the Battle for Gilneas near the Waterworks. It can be found by going up into the cliffs nearby, headed towards the piece of the Greymane Wall that is visible there. As the name implies, one can find a double rainbow here.
- The area and the associated achievement are a reference to the now famous Youtube video of a man video taping a double rainbow in the distance in Yosemite. Following this, he proceeds to somewhat overreact, even going as far to start breaking down into tears of joy. The video can be found below.
- Patch 4.0.3a (2010-11-23): Added.
