"Don't say that!" Elora rushes to Renaya's side, cautiously placing a hand on her shoulder in comfort. "Willitan is right, and it's bad to harbor feelings of self-loathing."
Verrian nods, still looking angry. "There's nothing more to be accomplished here. We'll return to the tunnels. If I can get within 60 feet of at least one of the members of the other team, I can use telepathy to tell them we've succeeded."
"Willitan, you know these tunnels better than we do. Can you lead us to the exit that the other group has most likely taken? We have to tell them to retreat before any of them get hurt."
Verrian should be able to jam the lock to give us some time to escape. It's a Disable Device check. Unless we want to collapse the cave, that's all I can think of. Maybe move a shelf from the storage room in front of the door as well
