Lir Qethserigir, Draconic for Worm Spine, began a subterranean military road. From Du'ul Hiim, it descended down several thousand feet, then went south in the direction of their enemy, the Theocracy of Galirkrad (1301 HE - 1725 HE). Expanded since the fall of Galirkrad, it serves as the artery road linking Ashmerthoon's capital to its many other holdings.
Lir Qethserigir begins at Du'ul Hiim and then heads south to an ancient complex beneath Viing Prolgiid. Along the road, are many side roads heading off in all directions, including to the surface and some leading deeper into the Underdark. One of the roads is the Staal Strah ("Port Road"). This road leads to the coastal city of Vaknor Gevild.
