Azir Lore Discussion

Azir is directly from shurima, what nasus and renekton are from another planet. Nasus says "perhaps shurima was meant to fall", which states that shurima is part of his race's history, Azir knows who Xerath is which further supports this idea.

My idea is that their race is from shurima, but something happened and they left for another planet, nasus was eventually dragged to valoran and now resides in the old residence of his people. Xerath and Azir are probably from a time before Shurima fell.

Riot updated nasus's lore a while ago, but it still states he lived on another planet. Additionally Nasus's lore states that his race served as the rulers and protectors of the people and that some of his kind believed they were ascended to become gods, which implies that humans live on Nasus's planet, which also further supports this theory.
