Usually not big on vampire themes, but this story has me really captivated. I like dystopian settings and the way bad ends are more elaborate than just a game over screen.
SPOILER
To make a comment on that point in the vampire alternative bad end branch, holy hell Amber meets a grim fate. Loses everything, including willpower, and meets a demise worse and more undignified than death. It's very reminiscent of future sight/precognition of good guys losing in movies. Akin to the Mirror of Galadriel in LOTR.
Having Maye's recollection of Noctorna's fate as a future sight to Mila in the main storyline would actually be so cool. As a way to show Mila the importance of her efforts and maybe incentivize some sisterly love since regret is stronger than gratitude
