Rerir left Vedrfolnir in the prison, so I'm not sure how he managed to regroup with the other sinners when they took in the abyss. There's some weird time travel shit going on with Vedrfolnir's mind whispers anyway.
It's also not clear what bad things Hroptatyr and Surtalogi did aside from leave. That's Rerir's only sin too, aside from being a Khaenri'ahn KGB officer that murdered dissidents of the previous regime, and the wild hunt stuff that came after he got torn into pieces going through the moon gate. Could the sinners have even made a difference if they'd stayed?
Rhinedottir is the only one actively presented so far as causing direct damage through her abyssal pets, although even that was maybe unintentional. More like unlocking the door to her research zoo. There were other abyssal monsters that invaded too.
>The shades got mad at all this shit and cursed Khaenri'ah
It was also to protect irminsul (the en localization of the tree, not the king), similar to Nahida being forced to erase her greater lord Rukkhadevata in Sumeru AQ.

>Asmoday somehow died and Paimon was born. You fished Paimon.
This part isn't confirmed as far as I understand. She seems to be written out of history entirely, as if Istaroth secretly did something. Paimon's true identity remains undetermined.

>But we can more or less infer that we'll have some big moment where Tsarita revives the third descender and shit happens. It angries the shades, or HP comes back and gets mad.
Maybe. I expect there will be some twist.
