So, Aurelion is the creator of all stars. That would include Runeterra, as any planet is in fact a star. Why is he so "unpleased" about Mt. Targon then, which he created by himself? And why this area of all on the planet?
Ah, but planets are not stars, and stars are not planets.
Planets are not stars and Stars are not planets, just because Aurelion Sol created the star(s) that Runeterra orbits around does not mean that he took any part in shaping and creating Runeterra itself.
Riot's lore department was all launched into the center of the sun a few years back.
