Legends speak of The Calling, a time of great turmoil when the old gods seek to wake. Calamity plagues the land as ancient powers attempt to retake the world. But in all these legends, a hero has always risen to defeat the old gods. This hero is called the Messenger, a magus gifted with true magic. Now, in the modern era, the power of the Messenger has manifested into two bodies. They are Nikita Takahashi and Chaos Maxwell, two highborn magi who now share the same life and the same responsibility.
