Your torch seems to flare up slightly as you turn away from the path to the outside--and instead head back down the hall to search for the source of the sound. You repeat what you did before, peeking in the barred windows, until you find...

something that definitely wasn't here last time.


It's... like... pale bamboo...?

Strung across one of the previously empty rooms.

You're not sure what they are, but there's a lot of it. You lean a bit, trying to see where it's coming from because it seems to just... be there, hanging from one side of the room to the other at various angles. Sometimes the ... sections? Twitch? An odd sort of jerking motion that vaguely reminds you of a stick bug. Without actually walking into the room to take a better look, your best guess is that maybe these things are lodged in all the various cracks and holes. You don't see any mouths (or any other orifices that could have made that noise), but it's possible that whatever talky parts it has are still in the wall, too.

That would explain how it got here, as well, if this thing (or things, plural) can travel

through ... the walls.
