Lost City

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 Plague Bearers shamble in big numbers around ruins. 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.
