The Mirror of Twilight (WoW)  

The Mirror of Twilight is the lake located in southern central Crystalsong Forest. The stream coming from the Twilight Rivulet is fed by the waters of the Decrepit Flow coming down out of Icecrown. Players working on their fishing achievements can find many schools of Glassfin Minnow in the lake and stream leading to it.

Wrath of the Lich King required!
