The children of man carve their own path across the land.

Regnus, a planet once ruled by a divine tribe thrived using a mystic 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 history.

-Once, this planet was a sparkling paradise where the Gods lived.

The planet Regnus. A mysterious light "Engram" filled the planet and people lived in extreme prosperity. They were known as the "Bapharia Divine Clan."

The "Bapharia Civilization" they built spanned all the land in Regnus and they even held the flow of time in their hands. Thus passed centuries, millennia -

The Divine Clan left for the skies and the human age has come. People seek the afterglow of the Gods and explore the Bapharia ruins. Lost technology. Dazzling treasure. Dangerous monsters. Towering remains. And... the all-destroying "Beast of the Planet."
