About 5, we do get a premonition about the final days after Zodiark is killed and the watcher said that our echo granted that premonition to us. I myself don't find it too unlikely that Azem of the past had one of us helping Themis with Pandaemonium. *shrugs* or atleast be a possible reason as to why.

Also about the rant

I'm still going to highly doubt it since we would have to find some way to travel so far into the past. And I mean really far for that like way before Emet became Emet and quite possibly before our past life became Azem. We did travel with both Emet and Hythlodeaus and helped people. (It's what gave Emet the unanimous support to be given the seat of Emet Selch to begin with.) Next is unless we merge with all the other Shards then we would be too thin soul wise as well as aether wise to even really be able to do anything.

Plus if you remember since we've joined with Ardbert our soul is now denser than even what the sources people are. So the rejoining would still have to happen other wise when we are sundered our soul would be less dense after 9 rejoining as opposed to said being denser as the Nu Moh said after the fake ardbert appeared
