About our WoD/WoL
The original owner of our WoD/WoL soul fragments (who now has 9 out of 14 of them) was clearly an important person, the Amaurotine who spoke to us during the strange administrative part of the last MSQ spoke of this soul as recognizable among the 'thousands' (our and the one of Ardbert being of the same origin), and that he was a close friend of Emet-Selch.
It is also clearly stated that one of the Council members left, the fourteenth, in disagreement with the proposed solution and the sacrifice of a large part of the population. I think this fourteenth Council member wanted to do the same thing than our WoD/WoL in the face of adversity and challenge (which makes sense if we think it is the same soul), fight, give hope to his allies and never give up, which has, let us not forget, made him a legend in the future after the eighth calamities, inspiring the future generation.
It is also hinted that the apocalypse is surely a misuse of the creation magic, which materialized the fears and doubts of the Ascians. If it's the case, it means that by giving hope to the people, and by pushing them to fight, and not to give in to fear , the apocalypse could have been stopped.
After the Council "saved" the world by the repeated sacrifice of surviving populations, i think that it's once again this fourteenth who opposed the last sacrifice of future generations to restore the past generation, and that he is the one who invoked Hydaelyn with his lasts faithful friends by sacrificing themself to allow the existence of a future and not a return to the past (which would in no way protect the return of the apocalypse in reality, and of more sacrifices). Our character and all his equivalents in all shard (Ardbert for the First) is probably the heir to the soul of the fourteenth, and the others Hydaelyn's chosen his ancient companions.
About Hydaelyn and Zodiark
I still think that Zodiark is Evil, and Hydaelyn, if not Good, at least with good intention, the Flood of Light is not her responsabilities, and the sundering the only way to allow the futur to be born. I don't see her becoming an ennemy. She has never done anything evil against the people of the shard, and not even the original human, she did what she was ask for, and never asked for other sacrifice and tried her best to never become a easy solution to resolve problems like Zodiark
About Emet-Selch
The smile at the end, after asking us to remember them was... really something. At long last, he finally see us worthy, as the heir of the soul of his long lost friend. I find it quite beautiful
