Wow, thank you for such an elaborate explain. I love the plot for its complexity and depth, the story itself is unique, that’s why I really want to understand it fully. But since I’m not a native speaker I have to use a dictionary sometimes while playing the game. There’s only one thing left that makes me wonder. Why Iustirho would want to stop Zasaroja? If she not succeed then he will eventually die soon due to osphor poisoning. Or even worse, he might even become an unstable chimera and end up being trapped like the other chimeras. And finally, I want to say it again. The game is top-notch although this is your first project. I wish you success in your future projects.
Part of it is him just not wanting her to get what she wants out of spite.
But although Iustirho is massively self-centered, even he recognises that letting Zasaroja have free reign to do whatever she wants to the world all but unopposed would end in disaster - especially after seeing what just being exposed to Meleuma did to Yaldukra; even having stable chimeras being free to move around could be seen to be dangerous. In Telwas' ending path, you also see that wanting to keep Liesefranche safe is another major reason why he would consider dying or being sealed.
In any case, thank you so much for trying the game - it means a lot that you're looking forward to what will come next. It'll still be a while before anything can be shown for it, but hopefully the first teases / previews for it will be ready sometime in the second half of 2020.
