Swamped

Look. Maybe it's just a coincidence that the shaking started when the spell started going. Maybe it isn't.

Either way, it'll be easier to deal with the problem if everyone's awake.

"Sah," you reply.

"kadra kadra kadra kadra..."

"The hell is going on here, Crosswinds?" Bigfoot asks.

"It's not the spell," Mantis says suddenly. "It's something below us... wait, no, it's moving up..."

You check below the floor. Hells, the pounding is strong here. It's just like earlier, only here there's a spot without so much wood.

...and come to think of it, wasn't Elmin nearby, using the mask, when it happened before? Maybe it's not that she's waking something up, maybe she's drawing it to her...

You don't have time to think about that right now. You crawl closer to the weak spot and get ready for whatever's coming. As ready as you can, anyhow.

The shaking gets closer, and something pops up. It looks weird, like it's made of metal, with a bunch of spidery legs and two big drills on lengthy arms.

And it's turning those drills towards the floor up above.

On the plus side, it doesn't seem to be paying any attention to you. But what can you even do to something like that?
