Q: I am interested to know how unsundered Ascians such as Lahabrea, Elidibus and Emet-Selch avoided being kicked into 14 pieces by Hydaelyn
A: As you think back to the text towards the end Emet-Selch did imply that Venat let him live unsundered. In fact Venat did intentionally leave a tiny floor in her Sundering attack - a crack that Emet-Selch can wiggle through. Sort of like…yes it was a powerful attack but intentionally chose to do it in this fashion. So we said this in the actual game as well which is when Hydaelyn did the attack, it was a really strong one. It was delivered at the limit of her power so she couldn’t really fine tune it. So as intentional as this was when she did that big massive light attack that sundered the world, she couldn’t guarantee that Emet-Selch would live and she was kind of making a gamble. In fact what happened was, at the time that Hydaelyn performed the sundering, Emet-Selch was with Lahabrea and Elidibus (the time he was already out of being Zodiark core so he’s a little bit different than his original but nevertheless he was there) so they ended up joining forces, and escaped to the rift without being Sundered. You may recall if you read Tales of the Shadows that Elidibus, when he came out of Zodiark he ended up losing some of his memories as well as some parts of himself and that’s sort of the point in Patch 5.3 and when he “dies” you sort of know that he lost a lot in the process as well just like Emet-Selch. So yeah, basically they worked together at that time and escaped being Sundered.
She knew what would happen next. Thus, she enabled all that happened afterwards.
