The moon was completely hidden by clouds on the night you found yourself outside of the Ringleader's fortress, yet again. The scouting trips had gotten more frequent, though you only had time to go on a few of them lately. But Jass hadn't brought you out for a scouting mission, this time. The two of you wait for a patrol to pass and she brings you to the covered end of a tunnel. You two climb in and follow it for a while, until hitting what must be the wooden wall of the fortress. Gloob is crouched down here, inspecting the wall, not needing any light to see it clearly.

You ask what the tool even is, and Gloob starts to describe a magical length of metal fashioned after a knife that, when activated, starts to vibrate rapidly. It should be enough to quietly carve away at the wall, albeit slowly. You leave Gloob to his inspection of the wall, and head off to get some silver.

You hand off the bars to Gloob back in Azamire, and not long after, he shows up on your doorstep, carrying a sheet wrapped around the vibrating knife he described. He happily hands it over.

Gloob starts to run through... more of his social life than you bargained for, and around the twenty minute mark you cough and mention that you really ought to get going to the fortress. Completely oblivious, he wishes you luck, and you set off. Back down at the end of the tunnel, sure enough, Gloob has marked a large cutout for you to follow.

You're able to cut through the wall after a fair bit of effort, and finally, the chunk of wood settles. You set the tool down beside you and decide to leave it there, in case anyone needs to improve upon your work. Once you're done, you carefully leave the tunnel and cover the entrance once again, before reporting back to Jass. She sends for a few people to go continue with the rest of the tunnel and assures you that it'll be ready for when you need to get the prisoners out.
