Darkwhisper Gorge

This treacherous system of tunnels, caverns, and chasms, lies along Winterspring Valley's southern slope. Poisonous green vapors bubble out of acid pools deep within the bottom of this gorge. Maleveolent sounds echo from a cave at the furthest end of gorge, leading many night elves to believe that demons may have taken refuge in the toxic depths.

A network of tunnels and chasms filled with elite demons of 5 man difficulty, in the far south of Winterspring. This area houses the gate to Hyjal, you can find the green portal barred off near the end of the gorge.

The demons in this area are used in the warlock doomguard quest.
