Suddenly in response to Gobuske's order a large clanking sound could be heard in the distance. One of his goblins manually activated one of the prized contraptions made by his goblin engineers. The goblin pulled a large lever that released a massive spherical boulder, a heavy wooden bolt then smashed into the back of the boulder causing it to fire out and down the hallway. The thing was easily 3 metres in diameter, filling out practically the entire path.
The device was set up out of sight of Findlay and his soldiers. The hallway curved to the left and right near the end, like Y and was built with an imperceptible incline, designed just for this trap. Quickly the large boulder barrelled around the corner and started picking up great speed as rolled down the hallway, heading straight for Findlay.
