why are monsters invading the cities?

[Jinrya-Geki]

Its just as possible Atomos has nothing to do with any of this and is simply interested in harvesting the aetherytes for his own reasons(or whatever it is that he is doing to them), the voidscent creeping through the cracks that process creates. After all theres nothing really giving him a motive to create Nael van darnus' to attack Uldah since he's been going about his business pretty much unfased this entire time he didnt set out to attack adventurer's only ones that are a threat to his continued feasting(or whatever).

Far more likely the entity causing the current attacks is related to Dalamud itself since not only voidscent and Nael van darnus' are attacking but also monsters of all kinds when by all accounts they should be fleeing. Either monsters are being possessed by some sinister evil or they are being attracted to Dalamud which Uldah happens to be in the path of. As was said earlier Nael's essence was seen entering Dalamud so its not so far fetched that Dalamud is related to the sudden appearance of Nael clones.

It's similar story to how Atomos was following Ex-Death.

FF5- Atomos
FF6- The World is going to be destroyed and remade.
FF7- They using Dalamud as Meteor
FF8- Time Compression, to us the player only.

Atomos confuses me, cause you figure at one point in time Aetheryte energy would be the most abundant, yet he comes to our time where it is the least. The unanswered question is why.

It is a mystery, but perhaps its not the aetheryte energy which he desires but the lack of it? if that makes any sense at all. Like maybe a byproduct of aetheryte energy having been spent. In which case it would be buffet time for him. Or for some reason Atomos is tampering with the aetherytes in preparation of Dalamud or the contents within. Landing lights maybe? =P
