If someone would have wanted to save Westfold, it'd have made a lot more sense to do so much earlier. Honestly I'm surprised no one stepped in, though. Luria made it look like they would, for a while.
Westfold could be saved by another monster invasion, though. Astrum is stretching fairly thin. Though they've done well in the last invasion, I suspect the monsters could distract them enough for Westfold to retake a few regions. Doesn't really look good for them, though. How long until they starve themselves?
