Q: What races were on Azeroth before the coming of the titans?
A: Besides the elementals, the only known sentient races on Azeroth when the titans' forces arrived to subdue the Old Gods were the trolls, the race known as "faceless ones," and the aqir. Due to the Old Gods' war against the titans, as well as the extensive terraforming that followed the war's conclusion, records of what races existed before even the Old Gods' arrival have likely been lost forever.
