It seems to me he's just a creature that feeds off of Aetherial energy, so he goes to the places with the most of said energy, the Crystals. Nothing more involved than that.

Ding ding. But I wouls go on to say that Atomos is important to Eorzea and other realms, his appearance was after the aether became unstable, not that the aether became unstable because of Atomos. When Atomos pops into existence in our plane clearly a rift is opened and things on the other side can come through, but once he goes back so do they. I would argue that Atomos came to Eorzea when the aether flow was at its weakest. Ifrit, Garuda, Van Darnus all were harnessing the aether for their own needs (Van Darnus was sending it to Dalamud). Aetherytes are places where the aether flow is strongest and we use these for our own purposes, I feel that Atomos engorged himself on the excess aether of the crystals and turned them orange causing them not to be as active.
