If we do race back to the convoy maybe
Illusion some "possible attack incoming" notes when we are close enough to be hard, since we will be reacting openly anyway?
Just an idea.

I do like the idea of the Hold actually having been switched in relative space via magic (and frozen in time too?), and this being kept up via the waystone. As that is (potentially) the least bad set of circumstances that come to mind.
Though I forget when the hold vanished and what else was going on at the time.
Edit:
I'm pretty sure this isn't correct, given that the following quote implies the outside of the mountain looks roughly the way it did before Karak Vlag was founded.
Same on the outside, different (no ore) on the inside. Strange. Strangeeeeee. As in "motivation for this, if an attack is strange".
Why keep the defensive utility of the external mountain shape the same, but remove that which is considered mineral wealth?
Maybe, as someone stated, the dwarves prospecting where the old mines used to be are having their heads fucked with.... maybe those mineshafts have not been filled with "worthless rock", and that's an illusion, but changing the overall shape of the mountain (in an illusion way) is more effort that it is worth?
Maybe the external parts of the holds have been removed, and the "mineshaft filling" is illusion - again, any such depict would have to stand against a quick glance by Teclis, so that why I think the external parts are really gone.
The dwarves inside are dead or in stasis or something.
