"This laughter is not just strange, sir, but eerie," Stephan whispers back. "Andreas will wait by this door and I will guard the front, while you are gone. We'll see it if anyone leaves."
(Being so close to the edge of the town, you don't need to fly far to find an isolated spot. You cast Voice of the Bjornaer successfully. I'll assume you cast the spontaneous spells with fatigue and that you rest between them. So the total time you are away is about 10 minutes. I will treat the "Ears of the Dog" spontaneous spell as giving a +3 to hearing-related rolls. The duration for both spells winds up being Moon. Had you cast them non-fatiguingly, they would have been duration Concentration/Diameter.)
When you return, Stephan is near the front left corner of the warehouse, watching to see if anyone exits through the front door. As you descended, you saw that Andreas is still at the back door. Where do you land?
