The tight Yiulong Canyons existed as a set of slender canyons situated on the desert world of Jakku. Niima, who was a Hutt, exerted authority over every vehicle and person passing through both the canyons and the profound Caverns of Bagirlak Garu found on Jakku. Past Niima's canyons and caverns lay the Valley of the Eremite.
