Non-playable race that I wish was playable
Who doesn’t want to be a sphinx-like being? They look so awesome and powerful. Not only do they look good but they were created to maintain Titan repositories and machinery. I don’t know many other races who are as close to the Titans than the Tol’vir. And if you don’t know about them, they are based on ancient Egypt which means gold, pyramids, sand and all the mysticism that surrounds them (which is why the designers used the Egyptian basis because the gods and goddesses are like the Titans).
Uldum was a fun zone and the lore along with it was great to read and experience.
