I agree. It would be neat to see the Highvale come and join up too.
Doesn’t really mean they’re gone though. But this will be a big hit to them.
We don’t know enough right now to say whats up anyways. For all we know they all got out mostly.
Spoiler
With the suggestion of what happened with Khadgar I suspect he may have teleported most to a relative safe place in the ensuing… chaos allowing for most to survive. (people of Dalaran I mean).
