Swamped

Whatever he's doing, it seems to be calming him, at least for the moment. So you may as well leave him to it for now.

You're more concerned with how that book got there. It's probably not Long's - it was under Marshall's bunk. And Marshall didn't seem to recognize it either.

Maybe this isn't the first time this cell has been used, though. Maybe somebody else was held here and left it behind. In which case - what happened to them?

Of course, you've also been having objects pop up out of nowhere for a while now - but then again, this is supposed to be an anti-magic cell, and you've seen firsthand what it did to a magical construct. So it'd be weird for a magical gateway to turn up in there.

Well. What if it wasn't magic? What if it was an ordinary hole or something? That still raises questions, but it's something you can look into. You head back into the cell and look under the bunk.

It's quite dark here. You can't really see anything. You try poking your hand around the wall and floor, but you don't find anything.

Maybe it slid in from under the other bunk? With the way the ship's been shaking recently, that's not impossible, not to mention it tilts a bit naturally. You suppose it can't hurt look, so you poke around there.

You think you feel something. Not a hole, though... something solid. Another remnant from a past prisoner, maybe? Feels kind of small. At least it's not moving.

Well, you may as well see what it is. You pull it out and look at what you found.
