Swamped

You pull out a device.

"Simone had some ideas when she got back, so she gave me this once she finished putting it together. It's an audio transmitter and receiver. It should have enough range to get down into the hole so we can have our conversation safely."

"Well. If nobody minds, then, I'm going to get on my mount early," Corvus says. "Mine's slower, right? I'd rather have a headstart. You can use that thing if you need me back here for some reason, right?"

"Should be able to. We should all be ready for a retreat, just in case."

You get everyone near the sandrunners, and watch Corvus ride off. You're not sure how this is going to go, but at least you're as ready as you're going to be.

"Whoever's down there, identify yourself!"

There's some talking that sounds like another language. You're having trouble telling if it's just one voice or multiple.

"If you can understand me, respond in Common! I'll be able to hear you."

There's a pause.

"I don't know how you're doing that without any magic, but you had better make this very quick," someone says. "We're in the middle of something very important, and we cannot afford interruptions."

"That's what we want to know. What are you doing down there?"

You hear some chatter again. You think there's at least two different voices?

"We're trying to clean up a mess someone made here. That's all we can tell you."

Well. That's an answer, at the least. How should you respond?
