Roughly 600 years ago, in the early 1400s, a powerful sorcerer clan, the Unzas, conquered the supernatural kingdoms. Their territory spread over 20 realms and they became the first supernatural monarchs to rule more than one race. Through them, the first inter-realm political order was formed, which they tagged the mystic world. However, they were cruel rulers. Their method of governance was harsh, and their goals were mostly selfish.
