Atomos shows up again in the WoD in the form of three of the typical Atomos enemies we've come to recognise and a giant orange/red crystal hovering between them.

During the battle with the three enemies the crystal heals them. In the combat log, however, it states that the crystal is Atomos Prime infusing them with aether to keep them alive!

Does this mean that the crystal was the true aether crystal core of the primal, much like the crystal in Bahamut's chest housed Bahamut Prime? Had it even been confirmed that Atomos was actually a primal in XIV?

Either way we now have two Primes... which is begging some questions.

Does every primal have a Prime?

Can we infer any similarities to XI's system of Prime avatars (whereby the Prime is the true original and the actual summoned entities are just manifestations of that original)?

When we slay a Prime does that mean they can never be summoned again?
