Quality droped quite a bit, particularly Main and Tuuli's faces during the contract scenes.
End of the story to be told... They probably should have said: End of Main's story, after that is Rosemyne's

So Sylvester really was the top dog after all... greyrobes knew, he was too carefree and probably also enjoying some free time for a change. I now also understand why so many knights were present when he fought alongside Main, but also why that very powerful attack. He was the target.

His statement about Main's familly totally shows us how that world works, like we've discussed before: you have power, you totally do anything you want with those under your power. Greyrobes, that knight, and now commoners. Even killing them for your goals is totally common.
It really puts into perspective all of Benno's warnings.

Now Sylvester gains a large mana power bank with technological knowledge to speed-up progress and benefit his domain.
Main loses ties to her familly but is not physically dead.
That way it's also easier to end that case with the high priest and that foreign noble: none of the victims/culprit are there anymore. Convenient.

Didn't see that coming, Sylvester and Ferdinand being brothers, even if only sharing their father. It doesn't add much to the story other than giving depth to the trust they can share, since they remained close from childhood.
