Galactic Skin/ Shurima Theory

So I was writing a novellete on Shuriman lore earlier and I noticed something. There are three Galactic skins in the game- Nasus, Renekton, and Azir. All three are Ascended and all three are from Shurima. Shurima obviously resembles ancient Egypt in many ways, so my thought was that perhaps these skins were a very subtle nod by Riot at the conspiracies that the Ancient Egyptians were visited by aliens. If so, bravo Riot. I would be thoroughly impressed.

P.S. I attached a link to the story I mentioned if anyone is interested
