Azir a previous inspiration

Azir. You know him, emperor of Shurima. But he is spcial... Inspired by the character Illidan Stormrage from the Warcraft universe with his words "No sacrfase is too great!!". It seems he is hidding something in his past... He will rise again to defeat his biggest enemy who we don't know yet. Do someone knows what destroyed his Empire and what was his sacriface? Azir is wise and he is not a bad guy. I feel there will be a lot of new Surima content comming in League! He will ryze again but his victim too!
