Neferset tribe

The Neferset tol'vir are a group that decided to side with Deathwing in exchange for reattaining their stone bodies, lost due to the effect of the Curse of Flesh. They maintain a strong presence within the Lost City of Tol'vir, as well as several more regions of Uldum and even Skywall.

Story
During the Uldum questlines, adventurers encounter members of Neferset on numerous occasions, first time when they arrive along with Adarrah and her caravan through the Gate of Unending Cycles and are captured by a band of pygmies and are sold for 3 coconuts to the corrupted tol'vir (although they're surely worth five). Thanks to Addarah and Budd's plan, however, they manage to free themselves and the Ramkahen Prince Nadun.

Before the escape, it is revealed that Siamat, Lord of the South Wind, was empowered by Deathwing himself to bestow the gift of stone skin upon the tol'vir, removing the Curse of Flesh. After becoming exhausted from converting the population of Neferset into their stoney bodies, the Neferset turned on Siamat, trapping him within the tower at the center of their lost city.

The Neferset's main bastion is Neferset City, located in the southern region of Uldum by the sea. However, after and death of Dark Pharaoh Tekahn, the Neferset forces are scattered and retreat into their last bastion and new seat of power - The Lost City of the Tol'vir where players first encountered them.
