The sethrak are a race of serpent people living in Vol'dun on Zandalar. The sethrak are an empire on the rise and throwing a wrench in everyone's plans. Wherever the sethrak go sand begins to spread as they magically change the environment into what they are comfortable with.
The sethrak once lived together as one as their loaSethraliss would have wanted. Thousands of years ago, they and Zandalari trolls lived in harmony in Vol'dun and worshiped Sethraliss together.
During the war between the trolls and the aqir roughly 16,000 years ago, the C'ThraxMythrax the Unraveler descended upon Vol'dun. He slaughtered troll and sethrak alike. Sethraliss sacrificed herself to save them, but though she struck Mythrax down Mythrax was still able to destroy the disc at the heart of Atul'Aman. After witnessing the destruction firsthand, the sethrak knew that something had to be done to prevent anyone from raising Mythrax again. Sulthis, Vorrik, and Korthek worked together to seal Mythrax within the great pyramid. Following Sethraliss' death, the jungles of Vol'dun transformed into a vast desert, causing most of the trolls to abandon the region. This left only the sethrak, who continued to survive and thrive in Vol'dun, which they considered the holiest of holy grounds.
Millennia later, Korthek grew power-hungry and sought to free Mythrax to conquer Zuldazar. He gathered like-minded sethrak that became known as the Faithless and declared himself emperor. The sethrak who follow Vorrik and still worship Sethraliss, known as the Devoted, have been fighting the Faithless ever since.
