So either we didn't sacrifice ourselves in the summoning, or we weren't part of the group.
Well seeing how our normal primals dont need souls to exist, there could be a possibility that Hydealyn was also summoned way different than Zodiark. Maybe this is the reason why the 14th left? They had other ideas but the rest wanted to use it like they did in the end? Maybe the 14th found a solution where she only needed some aether of their bodies but not their souls. Maybe they needed to bind themselves to her which then could be a reason why people with the echo can turn out to be WoLs.

We learn with 5.1 that the memories and the souls are two different parts thus even if we can transport a soul it could mean that the memories of the person itself is lost. So maybe Zodiark was created by giving all to it and Hydealyn was created to give their memories to her and a part of their aether (thus they died) while their souls remain intact. This could also explain why she is not aether hungry at all. She simply "eats" the persons memories after their soul pass through the lifestream. Which is also one solution to start anew. But that is pure speculation right now.
