How long these snakes actually could live? They are immortal?
The sethrak once lived together as one as their loa Sethraliss would have wanted. Thousands of years ago, they and Zandalari trolls lived in harmony in Vol’dun and worshiped Sethraliss together.
During the warbetween the trolls and the aqir roughly 16,000 years ago, the C’Thrax Mythrax 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
16000 years ago our snake friend Vorrik was around… and today he is quite fit - okay, almost died, but not really an ancient, withered snake guy, heck, even Valen looks like a prune… compared to him, Vorrik is an athlete, like Malfurion or Tyrande
So not only the Sethrak are more more ancient than the Night Elves, but… they are either extremly long lived or near immortal?
