For the city, see Aerie Peak.

The Aerie Peaks are a distant foreboding, mountainous region even beyond the realm of Quel'thalas where Wildhammer dwarves live and ride the wild gryphons.^{DotD 34} It appears to be a separate region from that of Northeron (although it is possible that Northeron is an area within the Aerie Peak region). ^{DotD 123}. The dwarves living in the Aerie Peaks practice hurling their hammers, for sport and for war.^{W3Man 5} During the Third War, even though the scourge never touched their high mountain home^{A&HC 58}, they chose to side with the Alliance, bringing the gryphons of the Aerie Peaks.^{W3Man 7} The gryphon is the symbol of resolve and fortitude among the wild dwarves of the Aerie Peaks.^{MoM 54} "Together with the humans, dwarven riders gave the greatest care, providing lodgings that would most closely resemble the Gryphons’ aeries among Lordaeron’s Aerie Peaks."^{W3Man 8} The capital of the Wildhammer dwarves also shares the name Aerie Peak, and is part of the Aerie Peak region of Lordaeron.^{MoM 54 A&HC 13,58} It is the location of the famous Aerie.^{DotD #?}

Speculation

This article or section includes speculation, observations or opinions possibly supported by lore or by Blizzard officials. It should not be taken as representing official lore!

Aerie Peaks is not mentioned in World of Warcraft although it does appear in the RPG where it seems to be implied that the city was named after the mountains that it's carved into. It is also speculated that either Metzen forgot, and now uses the city as a reference. It was speculated by some that the land of Northeron mentioned in Warcraft II, was renamed Aerie Peaks or Hinterlands. However Day of the Dragon references both Northeron and Aerie Peaks implying they are separate locations (or at least Northeron is a subregion). Tides of Darkness confirms that Hinterlands existed during the Second War.
