Mirror Lake is situated in western Elwynn Forest, near an orchard. It is rather small and features a beautiful waterfall. Although Mirror Lake would be an ideal spot for swimming or fishing, the Defias bandits that infest the area make such sports hazardous.
The lake always shines brightly in the afternoon sun, which explains the origin of its name.
The sewers from the Stormwind Stockade exit into Mirror Lake and Varok Saurfang escaped through it. By the time of the Fourth War, Lake Crocolisks and Gutgnash appeared in the lake. Dark Ranger Lyana and the Horde champion tracked Varok through his escape route.
