Gholog and Jason fall back into the belltower, slamming the heavy oak door shut behind them. Jason heaves the iron bar into place to hold the door closed, while Gholog joins Seraphina at the Wyrmcall's rope. His added weight increases the volume of each sounding of the bell, and the crystal (now directly under the bell) is having to work without pause to keep it's surface unbroken.
"If you stop this madness now, I will let you all go unharmed." The stone's voice echoes into the tower from the assembled townsfolk outside. "I will make you all rich, if you will give me back to my people."
(OoC: A bit more detail on the construction of the belltower, now you're all inside it. It's about fifty feet height, and has at least three stories to it (going by the locations of windows on the outside). It's twenty feet square at it's base, and there's a flight of stairs leading up beside the door Jason's just barred.
Speaking of which, I hope nobody minds me acting for their character. I thought barring the tower door was implicit from the general theme of your actions.)
