Ironweld Great Cannon

The gate of the Castelite formation is the Ironweld Great Cannon. Protected by a thick shield, this mighty artillery piece is manned by an expert crew who ensure it fires a constant barrage of cannonballs, shells, and grapeshot. Firing only ceases when the cannon wheels forward to allow Freeguild Steelhelms and Cavaliers to sally forth from within their living fortification.
