As long as you control a Mountain, Summit Apes has menace.
"If you climb Skyfang Peak, avoid the pass. Generations of apes made that trail, and they don't tolerate trespassers." —Sachir, Akoum Expeditionary House
"Do you not hunt the yetis of the high peaks, stripling? Their meat is as tender as a bear's and their blood as warming as fire. They are prey that will please Atarka." —Surrak, the Hunt Caller
