Rusalka inspects the trap, triggering it relatively carefully before checking inside in case it was really just the secret entance they were looking for. Unfortunately, unless someone in their party and all the bandits were extremely alkaline, there was no indication this could possibly be, in fact, another way in. Which really was a good thing, since that meant the bandits couldn't come back this way and surprise them, or sneak back in a different, unguarded route. She (and especially Claudia, loudly in her head) really hoped they weren't alkaline bandits. That's a thing, right?

She went back out to the group, telling them all that was inside is stuff the bandits who had stayed there didn't want to take with them. And about the trap, of course, in case anyone wanted to check for a hidden entrance to their destination.
