Revelations from Patch 4.5

[KageTokage]

My thoughts on the voice:

It's been noted that some of what the voice has been saying is unusually similar to the Warp incantation used in FFT to send Ramza to the Necrohol of Mullonde (Against his will to boot)

I believe "Let expanse contract, eon become instant" and their other cryptic words that are hard to interpret may simply be part of some manner of incantation that's being used to temporarily connect its targets to another reality (Hence Alisaie noting that she felt like she was "somewhere else" whenever the voice was speaking) so that their minds can be pulled away (They naturally couldn't bring their whole being since we already know that you can't cross between the shards without relinquishing a physical form).

I'm thinking the only reason we haven't been pulled away yet is because we're still needed to keep things from going awry at the Source and that as soon our little Garlean problem gets sorted out we're going to get yoinked into another reality like everyone else so we can finally get a proper explanation as to what the heck is going on.

As for why they haven't been more clear about what they're trying to tell us, I'd assume that cross-shard communication is just extremely difficult to maintain...which is also the reason why the Scions were spirited away because they're going to be helping to sort out an issue that's much too big to explain in the brief moments they were able to hear the voice.
