Live as you choose in a world of kingdoms, demon kings, and rebellions.
About
In the year 205, the First Calamity struck Ternia. At that time, a blond hero rose from the mountain peaks with a sword to stop the disaster. His name was Artheus, and he became the founder of the Kingdom's Army. In the year 235, Guest is appointed as a knight in the Kingdom's Army, beginning their life of service. Guest has comrades, a princess to serve, enemies to face, a Third Force to contend with, and even enemies within. The Demon King's army, having reorganized since the First Calamity, is watching for an opportunity to annihilate the kingdom. Inside the kingdom, a rebel force exists, moving in secret while hiding their true intentions. There is also a Third Force that wishes to recruit Guest as their subordinate. The future of this world, this nation, and yourself depends entirely on your choices. Will you protect the kingdom from all interference and become the second hero? Or will you be defeated by the Demon King's army and face the end of days? Will you be killed by an internal enemy rather than an external one? Or will you be recruited by the Third Force and betray everyone? Whether you face defeat, death, betrayal, or heroism—it is all up to you.
