Regnus, a planet once ruled by a divine tribe, thrived using a mystical light. Many millennia later, what remains are their ruins, treasures, and a dark secret. Start your journey in this forsaken paradise, uncover its truth, and become part of its history.

—This planet used to be a paradise inhabited by gods.

Regnus, a planet full of a mystical light called the “Engram,” was prosperously ruled by ones called the “Bapharian Divines.” The Bapharian civilization they established covered the planet and even enabled them to harness the power of time.

Many centuries and millennia later, the divines have left for the heavens and an era of human rule arrived. In search of the remaining light, people stepped foot into the ruins of the Bapharia. Lost technologies. Shining treasures. Monsters attacking. Towering ancient structures.

—And a power to destroy all civilization, the “Planetary Beast.”

Fighting for the fate of the planet, a new page in Regnus’ history is about to be written.
