Firstly.

THERE WILL BE SPOILERS FOR THOSE WHO HAVEN'T FINISHED THE MQ SO PLEASE DON'T READ BEYOND THIS POINT IF YOU HAVEN'T FINISHED THE MAIN STORY YET!!

So as stated in the title I've recently just finished the MQ and have some questions that either that game hasn't either explained yet, I've misunderstood, or just plainly missed it.

So we find out pretty late that two of the ancient ascians became the heart of Zodiark and Hydaelyn. The heart of Zodiark being Elidibus. Now I know in a sense we didn't kill Elidibus as we merely trapped him inside the crystal tower. That being said wouldn't that cause some level of damage to Zodiark? I know that it's not like a human heart ect but still I would of thought us sealing away his heart would cause some issues.

This next question is more of a general thing. If the main purpose of the Ascians was the rejoining why did they spend so much time in the source when they could of just spent all of their time on the other shards where the Warrior of Light couldn't foil their plans? If it wasn't for the fact of our awesome cat lad summoning us to the first there would of been nothing we could of done to stop it. And even if we still stopped the first. If they were doing all sorts of crazy stuff on all the other shards we would of had no way of stopping them right?

Not really a story related question but. How strong are we? I do like the fact that we do get our asses handed to us multiple times to sort of remind us we aren't just unstoppable gods but at the same time even foes who whooped our asses we end up getting the better of them. At the end point of Shadowbringers is there anyone who can stand against us? Apart from the hunt crazed Zenos

Back to the story based questions. Y'shtola's aether vision is basically killing her right? Or is it just shortening her life span? If so have we ever been told how long she's got?

Are there any other Ascians left apart from Fandaniel? Is so what are they up too? Are they like him where they are now free to do as they please or are they still trying to cause the rejoining? As Fandaniel has gotta be making their life harder too.

This might not make much sense but did the ancient ascians bring about their own destruction? During the dungeon where Emet-Selch is showing us the final days I believe he mentions about their nightmares coming to life and in a side quest we find out that an ascian I believe made a chimera as he was trying to create a lion but saw a bird during the process and thus mixed up the two animals together. If all it takes is a moment of distraction to create that could the panic of their world ending have caused them to create monsters or made what was happening even worse by their own thoughts and magic coming to life? Or could like rumours all it could of taken was one paranoid ascian thinking "oh god the world is ending" to start the chain of events that then caused everything?

Thanks for any answers you're able to provide!
