Sûrag is an Underdark corridor that commences at Gholompotl. It proceeds northeastward to Mulun-Dûna. The passage continues through the town for five miles before bifurcating, with one road leading to Ghaundan and the other to Nurum-Maluk. Lining the Underdark corridor are numerous caverns and intersecting passages, including one known as Atúb Mol, which is fortified with walls and towers.
The Sûrag passage was expanded into the expansive Mulun-Dûna by the mighty Khazarkar Empire. Prior to the arrival of the Khazarkars in central Cinazan, the passage was narrow, perilous, and required three times the duration to reach Mulun-Dûna. It has since been significantly broadened, allowing two carts to pass simultaneously. The Khazarkar Empire oversees its maintenance, while soldiers from Mulun-Dûna patrol the route.
