Possible Iron Wolves Season 4 Theme Patch 1.4.0 PTR Datamined Changes
The Lost City of Ureh is tied to lore that many Diablo players may not know. Originally intended to be part of Diablo 3, it was teased in the cinematic reveal trailer for the game, but later cut — so players have never seen it in person.

Before its fall, the city of Ureh was one of the greatest cities in Sanctuary. Led by Juris Khan, its citizens prospered — but this prosperity drew the gaze of the Lord of Terror himself. Turning Juris Khan and his daughter into living vessels, Diablo turned the citizens of Ureh into undead abominations, attempting to use Ureh as a gateway for the Prime Evils to invade Sanctuary by transporting it to the Burning Hells.
One of Juris Khan's Archmages realized the danger and attempted to reverse the spell, transporting Ureh to the High Heavens instead, but only managed to send the city into limbo — present in neither Heaven nor Hell, the city was lost for thousands of years. Ultimately, a mercenary named Kentril Dumon was able to return the city to the mortal realm, however, its return to Sanctuary ultimately led to the downfall of Ureh and its citizens, leaving the city in ruins.
A potential vendor hut can now be found to the right of the entrance to the area. This looks like the perfect spot for an NPC to set up camp, with its own separate outcropping of space — indicating that someone (with applicable personal belongings, given the size of the space) might be moving in soon.
