IDK, she looked genuinely shocked when Marie-Anne defended the dragon on account of his treating her well, and expressed regret for berating her. Seems to me like there’s the potential for redemption there.
She wasn't shock that Marie-Anne defended the dragon, she was shocked that Marie-Anne turned her twisted world-view against her. In Valzira's eyes beast(males) rule by might and violence. It is the job of respectable women to twist beast desires and wishes to their whims. It's essentially might makes right but brains over brawn. The problem with her assessment is that the dragon trumped her in both. By her very assessment, she admits that she like Marie-Anne deserved to be a plaything to the dragon because the dragon was just exercising his right.
Ravager is a game great for power fantasy, you are playing a literal dragon. But not everyone is going to bend the knee before your might or fall for you. I see the appeal of changing someone like Val into a lovely dovey wife, but that would spit on the character itself because that's fundamentally not who she is. Naho and Val will NEVER love you, it's not in their nature. You can break Naho and make her dependent on you for the rest of her life. That's the only way to make her your consort, she NEEDS you. She hates your guts and the things you've done to her, but she can no longer escape your grasp. Because she will die a slow and agonizing death if she does. Her pack doesn't care for her and only supported her so they could fuck her. She has nowhere else to go because she devoted herself to the pack she was born in. The wolfbane has made her a sex addict whose only cure lies in being fucked by the one thing that ruined her life. But even though she's a broken-in pet who is forever shackled to you, she is still Naho. She still has pride in her accomplishments, still hates you, and still feels the same way about you and her pack.
This keeps in line with her character instead of twisting her into something she is not.
