If we bait them into resurfacing in this reality can we disrupt either the disappearance magic or the Vlag waystone enough to prevent them from leaving again?
I was thinking, first we pray really hard to Ranald that the deception will work.
Then we use Illusion to stage an arguement between us and the expedition, the expediton supposedly doesn't believe anything can be done/accuses us of lying about the mountain, and the current road and watchtowers being an illusion by a glory-seeking grey wizard, snorri, the rangers and us believe it's real and believe something has to be done.
We stay behind 'on our own'(possibly with Asarnil under illusion), and keep poking at the magic from a vulnerable-looking position, the Daemons resurface in reality to prevent us from figuring it out/kill all the witnesses/prevent us from blocking the waystone feed.
We try to avoid revealing that Asarnil is still here until the last possible moment, to give us as much time as possible to mess with the magic.
Can we burn the powerstone to cast an illusion with extra range/longevity, and make them think Deathfang left with the steam wagons, when he's actually staying? Or would the plan be dependent on Asarnil being ready to separate from Deathfang and fight dismounted?
Do you think that it'd be more effective to burn the powerstone to make them think deathfang had left, or to save if for an enhanced dispell on whatever magic this disappearance is?
We obviously still don't have the forces to take Vlag, but if there are dwarves still alive in there gettingnthem out of the realm of chaos ASAP is vital for their survival chances.
