I have started reading Centuria and here are my thoughts:
Elstri is the starting trigger of the prophecy. If she had half the brain of the Supreme King he would be able to survive the series. But then again its also the King's fault for allowing her to run around recklessly like that.
The sea god need to have restrictions on powers and that they can't be passed down it seems allowing it pass on create more mess than needed.
I can tell Julian will die at the end of this and I feel very said about it I feel like he should become the new king but I feel like the king kind of regrets being a king himself so maybe that wouldn't be a good ending for him.
If Elstri does not have a scene where she watches the king dies and doesn't have a realization she caused this all to happen I'll be sad.
