"What you do in life, Echoes in Eternity."

The System, who goes by the code name, Thirteen, defied the System God in order to give his previous Hosts’ the chance to change their Fates.

Unfortunately, he was killed by his Father, the System God, and was sent to the world of Pangea to struggle like the Cannon Fodders that he fought so hard to protect.

Armed with his knowledge as a System, Thirteen vowed to change not only his Fate, but the Fate of others whose destinies were tied up with him.

In a world torn by power and corruption, a fallen System will bring out a symphony of change, or lead it to its destruction.
