So I finished the gold road questline and after sealing away Ithelia, Hermaeus Mora's tone of voice is much more evil/angry, while his appearance is much deeper and darker green... Very different from how he has been since the start of Necrom. He seems very upset that we made him change, and like he has a hatred of Ithelia despite her doing the right thing...

So I guess does anyone know more lore on Hermaeus Mora? Is this typical of his behavior, or is the ending of the storyline hinting at something more, like Hermaeus Mora becoming corrupted?

Also, am I the only one who feels sad/like something is missing with Ithelia being gone? Like all of the West Weald feels wrong after the ending, and I just want Ithelia back. Since Abolisher was given the power to cut ties with the path Ithelia went on, wouldn't it be able to re-open the same path? I guess I'm kind of desperately looking for a way Ithelia could return, it just feels unfinished and sad the way it's ended. ):

EDIT: In hindsight, I also feel like I was being gaslit/manipulated into doing what Mora wanted the whole time. Every NPC, every dialogue: Ithelia bad, stop Ithelia. No choice. It feels like the story was building to a big surprise/plot twist where we find out Mora has been controlling us all along, and we end up siding with Ithelia to stop him, but it never happened... I really hope ZOS expands on this and we get to free Ithelia/stop Mora in some plot/twist follow-up. I need closure, and that's the only way I could get it.
