Nestlewood Thicket is an area in southern Ammen Vale, filled with owlkin. The owlkin have gathered the scattered [Emitter Spare Parts] here and in the Nestlewood Hills (see  Spare Parts). Unfortunately, some of the native owlkin have been mutated by the radiation from the power crystals that fell from the draenei ship the Exodar, and have become hostile to travelers. Some draenei are attempting to inoculate the unaffected owlkin to keep them from being mutated like their fellows (see  Inoculation).
Nestlewood Hills is in the draenei starting zone and most draenei should reach this area around level 3-4.
