Kingmaker GM assistance request: Book 4.(spoilers)

[hkidnc]

Long story short: The party is 1 room away from Armag. Armag has left to go attack Drelev, for a variety of reasons (Tie things into book 6 better, punish the party for ignoring him for almost an in-game year, etc.)

The party has a wizard who tends to teleport them everywhere, so it's unlikely they'll stop by drelev after finding the tomb oddly empty.

The ghost guy is still alive (at present) But we're due to pick up fighting him as soon as the next session starts. Like, we ended last session with the party barbarian preparing to charge the guy.

how do I appropriately lay down some Cookie Crumbs to get the party to head back to fort Drelev?

Smoke in the distance as they leave the tomb, before they teleport.
A feeling of "something was here and we missed it".
The "ghost" cursing everyone with a dimensional anchor if they kill him..?

How much time have the PCs spent in Fort Drelev, and how well are they known to people there? Someone in Drelev should be capable of a sending or animal messenger. Preferably just after they've wasted the resources to get to the wrong place.
