Which main hero did you like the least?

No, he should have at least shown some regret. Personally, if I were killing a friend, I would at least say a few more kind words. But in general, I wouldn't kill a friend! Besides, if Faidaen wanted what was best for the country, he wouldn't act like a maniac, but would actually protect it. As soon as he sees someone's army, he immediately draws his sword. What kind of diplomat is that! Zehir had to calm the heated elf in the end. And what about Isabel's fate? He doesn't look like an elf at all. No, I'm not saying he should be handing out flowers to everyone and always be polite, but this is too much.
And I would send Izi away myself. She has caused so much trouble, and she hasn't learned anything. She thinks she's brave, but in reality, someone else does all the work for her. However, now no one will send her anywhere, as long as Railag is with her.

Forest Flower, you are simply an amazing girl, if you didn't kill a friend who devastated your homeland and is ready to finish you off... And I don't see the point in saying kind words. If Nikolasha is of sound mind and memory, why did he lead an army against his best friend? If his mind is enslaved and he doesn't understand anything, then all his words are a farce, and he is using the question about his fate to evoke pity for his own benefit. And his consciousness somehow selectively awakens... What an inconsistent vampire, I swear!

I attribute hot-headedness to evolution – along with aggression, musculature, etc.
IMHO, not trusting anyone but yourself is normal, especially in such a turbulent time, especially when it comes to dark elves)))

And I already wrote about Isabel's fate – with his statements about this madam, Faidaen won me over))) If they had left this queen in Shio, as he advised, the Griffin Empire would have avoided many problems.

Oh, I feel like I'm acting like the devil's advocate))))
