Designed by the Archmage [Gunther Trignum], they are called Gun's. Not long after the invention of Gun's, they created a magical tool designed to imitate humans, known as the Automata. After these inventions were introduced, the Kindom declared the development of Magic spells forbidden to public and can only practiced by the Army and the Royalty. In exchange, they promoted the use of the Magical tools provided by the Kingdom. With the advancement of technology, manual labor was no longer needed.
