Atomos and Over Aspected Aetherytes- Method or Madness?

[Fusionx]

I think Atomos is summoned by Louisoix.
Note how he "samples aether" of people as we fight him.
Perhaps its to make it easier to protect us during the fall of dalamud if Louisoix has a "sample" of our aether?

This would imply that Louisoix could be the reason why there are voidsent in Eorzea... not sure if that really works.
