It was discussed briefly in another thread. So, the thing is, there is no information about how could Shadowlands exist and be so effective for who knows how long, why convenants do what they do, etc.
The memories that kyrians expell from themselves for whatever reason are very similar in the visual representation to what can be seen in the Maw. So what would truly happen should they not ever do it - to be explained. Maybe.
Maybe eventually it’ll be know how she made the transition from being horrified by the Maw to being an ally of the Jailer
When was is not the case in WoW…
IMO a problem at the moment is that different sides can have more or less valid motivation for their action. However, instead of telling the story where we learn bit by bit about how the things became like what they are, the devs seem to think that “plot twists” is the best things to have.
So a lot of significant information that would make sense to figure out early instead is postponed till some point in the future. And given troubled development of some expansions, sometimes this future never appear at all, so story lines left unfinished or do not make much sense.
