One of the mightiest machines built is a twin-armed catapult that requires the strength of two green drakes to be pulled:
While the drakes are just as sentient as all dragons, Argavius, leader of the palace guard, was bestowed with the command of the artillery unit that is to increase the military might of the Dragon peaks.
Able to launch massive rocks as far as 300 meters, enemy troops will forthwith be hard pressed to get near the walls.
More pictures can be found at Flickr. C&C are most welcome.
Note: This is a modified version of the official catapult, which was part of the set 7021.
