Being re-birthed as a cell, Han Dong utilized the power of the Prison code and came into a parallel world where the Ancient Ones have awakened.

The door of Destiny has been opened – Crusaders, Library, Control, Machinery and Mysticism would become the new growth system for human development.

The hymn of Humanity is the song of courage! The brave and dauntless Knights Regiments, riding into the world ruled by the Ancient King to seize back the freedom that belongs to mankind.
