Daemonum siege machines are massive, armored vehicles that are still under construction, invented and built by Mephisto and his evil Imp minions, planned to be used by by Baalzrodan's armies to assault the lands of Mundus. Daemonum siege machines are built by grafting souls of demons and fed with Simulacra. These infernal metal wagons are reinforced in spikes and blades to destroy any obstacle in front of them and are donated with a powerful cannon capable of breathing fire.
Nobody knows the catastrophic consequences that these siege machines could unleash to the realm of the mortals.
