Owl Wing Thicket is a series of caves in southern Winterspring. They host a large number of berserk, moontouched, and crazed owlbeasts. It is here that the ancient Guardians of Elune tell how the moonkin came into the world (in a quest chain exclusive to the Alliance), guided by Ranshalla.

Places to safely go AFK:

• On top of cave entrances
• South of southernmost cave on a cliff overlooking Frostwhisper Gorge.
