1. So why would he kill Nicholas? There were no such orders. And Kha-Belekh would be much happier if he didn't kill him.
Regarding Dmm&m.

2. After all, a hybrid of a demon and a non-demon is an orc. So why do Sareth and Kane, from the demilich's story, look like humans? Oh, and also

3. I managed to read the story, but it's too boring and illogical, and there are a lot of clichés.

1. Perhaps out of jealousy.
2. Nicholas's death is very necessary.
Then Biara can be placed on the throne, and he is the only one who knew how to use the griffin's heart (the rest of the dimwits buried it with him).

2 Orcs are a fusion of magical power from human mages and demon blood.
A half-demon is a human or an elf, corrupted by demonic magic.

3 I also want to know where the demilich got this from.
Because in official sources, there is only a brief history by year.

The Ubisoft forum is much more interesting than the Nival forum; the Ubisoft managers tell everything in 5 languages.
Guess which language is being neglected? :)

p/s Thanks for reading it :)

In our time, without clichés??? It would be more original if Argail turned out to be of a non-traditional orientation and, after performing a true nature ritual, turned into an elf and left with Faidaen.
