Imagine submitting to Jezera and her pathetic teenage-minded, self-sabotaging approach to almost everything when you have this spooky, soul-eating witch around who is - in my opinion - ten times more manipulative, more charismatic, smarter and hotter in every possible way. She gives the "manipulative dominant vibes" you'd expect from a mistress and/or an antagonist. An enticing character that makes evil feels sweet.
Jezera is a very young girl in the story, Rowan is older than her. Arzyl has more experience and has lived much longer. 200 years later, Jezera will become "more manipulative". It is no wonder that Arzyl knows how to get Jezera on her side.I like Arzyl too, but I understand that Jezera lives twenty years, for a demon who can live thousands of years. Of course, if we talk about characters not about appearance, but about their capabilities.I would also like to see a continuation of the Arzyl story. I like Arzyl more than Jezera, but I understand that we only have 4 main characters.
If Arzyl was the main antagonist from the start, maybe it would have been better. Seriously, her actions are much more appropriate for a being who deceives others to achieve her goals. Unlike Jezera's straightforward approach. Jezera killed the leader of the dark elves because she did not want to give up part of the conquered territories. Arzyl would have simply deceived them and gained additional power in the war.
