"The First Domain was used by the True Gods to imprison Heavenly Demons, so that they could never escape. But the Heavenly Demons and humans formed an alliance. Humans, who once worshiped the True Gods, chose to betray them and released all those demons who were trapped inside the First Domain…
"The humans' betrayal destroyed the First Domain's imprisonment of the Heavenly Demons. The demons regained their freedom and many True Gods died as they battled against the Heavenly Demons.
"Those dead True Gods bore a deep hatred against the humans for their betrayal. Their godly souls disintegrated to form this mystic realm. This realm was woven out of the curse that the True Gods cast upon the traitorous humans.
