Lir Qethserigir, also known as the Worm Spine, began constructing a subterranean military road. Originating from Du'ul Hiim, the road descended several thousand feet before heading south towards their rival, the Theocracy of Galirkrad (1301 HE - 1725 HE). Expanded since the collapse of the Theocracy, the Worm Spine now serves as the vital artery connecting Ashmerthoon's capital to its numerous other territories.
Lir Qethserigir commences at Du'ul Hiim and then travels southward to an ancient complex beneath Viing Prolgiid. Along the way, numerous side roads branch off in all directions, including routes to the surface and some leading deeper into the Underdark. One such road is the Staal Strah ("Port Road"), which leads to the coastal city of Vaknor Gevild.
