Whistler's Pass
Descending from the high ridge of Zhindel's Post, Whistler's Pass begins as a rock-strewn, arid region blasted by chill mountain gusts and enclosed by high walls of sheer stone. The denizens of the Pass scurry among the crevices lining the rock walls, foraging a meager existence from thorn bushes and cacti. Utilized by both Elves and Dwarves alike, Whistler's Pass is a vital trade route through the Dragonspine Mountains and provides access to the Elven city of Ta'Illistim from the harbor town of Wehnimer's Landing.
The mountainous part of the pass near Zhindel's Post requires adventurers to have some skill in climbing to navigate (just about doable with 10 skill ranks). Trips down to Zul Logoth and through the Dragonspine Mountains requires riding mine carts, which typically cost 1000 silver coins one-way (2000 silvers for the full trip through).
The small arboreal town of Cysaegir, a sanctuary for the aelotoi people, can be found along the southern part of the pass.
