Riagan looked at the chunk that he had knocked down. It was a fair-size stalactite, but it wasn't long enough to cross the chasm. With a grunt, he pushed it into the pit. Looking over his shoulder, he shouted to the Professor. "Fae! You have any rope on you?"
The Professor finally stopped obsessing over the hieroglyphs and walked over to the group. "N-no, I don't. However, however I do have a flash-bomb..."
He dug around in his bag and produced a vial. Uncapping it, he lit the short fuse with his torch and tossed it into the pit. It fell a short distance before exploding in a bright light, enough to illuminate the walls of the pit for a few moments.
