But it turns out that Agrail killed Nicholas for nothing?
It seems so. Agrail failed to prevent the coming of the Dark Messiah; he only managed to delay it. On the other hand, it was thanks to this delay that Kha-Belekh was defeated. It is unknown what would have happened if Sareta had raised him.
And I still don't understand how Isabel could love Railag – the one who killed her first love, Nicholas??? Yes, Railag apologized, and he saved her so many times, but I still don't understand how you can forgive him for that??? In my opinion, after everything he did to the empire and Nicholas, he couldn't even dream that Isabel would ever love him. After all, it was obvious that Isabel loved Nicholas. If it were possible, she would have resurrected him a second time.
Probably, she fell in love first, and only then did Railag, without rushing things, tell her who he really was.
Remember the last video about the murder of Biara. Kujin said that Biara supposedly killed Isabel's husband. And then Isabel says to Biara, "My husband, my country, you will have to answer for many things." I was waiting for Biara to tell Isabel the truth, and Isabel would hate Railag. But, alas, a happy ending with wild laughter prevented this.
In short, Railag, it seems, lied to Isabel. He is not as simple as he seems. However, as befits a dark elf.
