The Lost City is a zone that features a lot of ruined buildings and is divided by a cliff. 13 Seconds after entering, a sudden eclipse occurs, the Tainted Sun quest would activate and plunge Sanctuary into a perpetual nightfall until the Tainted Sun Altar is destroyed.
The Night Slingers here use poison potions, which makes them more annoying than usual. A trap door found within the city leads to the Ancient Tunnels, an area not unlike the Sewers beneath Lut Gholein.
