If I remember well, there was talk that the Dalamud getting near caused the Aethers to be "pulled out", as depicted on the artwork Tonkra posted, so perhaps this is an extreme of Aetherite being sucked out the most where Bahamut and Lousioux clashed. Still don't fully understand where Atomos fits in relation to Aetherites though. . . .

I'm willing to bet my subligar that Lousioux is in fact "trapped" there, in some shape and form. A quest line to reveal that, in fact, he's been either turned into Aetherite/and or trapped in Aether crystal :3 At this point, he's too much of a big deal never to appear again, if even as a ghost or an echo.
