With a post-apocalyptic background and opening a new era for human history, Crystalis will take an adventure and fight against the evil of a Young mage. In 1997, a new world war broke out and the participating nations activated the nuclear weapons systems they owned. Since then, the modern civilization of mankind has been destroyed. The survivors of the war returned to live in the Middle Ages after the use of machines or electronic devices stopped working. In addition, some residents after the Great War were contaminated with radiation and became mutants. Facing this harsh life, the survivors decided to research and build magic systems to help support and restore the human environment. In addition, they built a tower in the sky to prevent wars and disasters that threaten the survival of mankind. In particular, who can control this tower will control the world because it possesses a powerful weapon system. However, a person claiming to be Draygon built the Draygonia Empire with a mighty army. He combined magical powers with forbidden scientific studies to control humanity and seek to seize the tower in the sky.
