So where this 9.1 Anduin Story Arc is concerned, to my mind (and feel free to disagree with me here) - there are 4 directions this story could take and make a medium of sense. Very basically here are my thoughts:
- In the later part of Shadowlands - we kill the Jailer and thus break the “bond” between Anduin and the Jailer, thus freeing Anduin (most likely) - POTENTIALLY with the assistance of Sylvanas depending on how the story arc with her plays out after we’ve defeated her (remember just because we’re fighting her doesn’t mean we’re killing her)
- We fight both the Jailer and Anduin and kill them both (VERY unlikely I fancy)
- Anduin (potentially with our assistance or Sylvanas’) somehow manages to break free himself (we have already seen Anduin in the latest cinematic briefly break free before the armor took hold of his mind once again) and thus is instrumental in taking down the Jailer (possible but not as likely)
- We kill the Jailer, the bond is broken and Anduin freed from the Jailer but still corrupted by the armor becomes like Arthas and begins his own story arc as an even greater threat than either Arthas or the Jailer taking us into 10.0. (Could be fun! But I doubt it).
Just my two cents on how this could potentially play out - we’ll find out for sure in time, but its fun to theorise isn’t it?
