In ancient times, Longju was a united and harmonious empire where dragons soared through the skies and magic flowed freely. That peace was shattered when a Dark God sought to bend the power of the beasts to his own evil purposes. Alongside this malevolent god came mysterious stones that fell from the sky and brought disaster and chaos with them, known as the Dark Stones.

The Dark God also sent his servants to hasten the spread of darkness. Among them are the Demon King, who established himself in the Demon Tower; the Orc Chief, who dwells in the Orc Labyrinth; the Baroness, who seized control of the Spider Dungeon; Azrael, found in the Devil’s Catacomb; Beran-Setaou, settled in the Dragon Cave; and the Demonic Butcher, who serves in the Enigma Temple. These servants spread ruin across every corner of the land, fuelling conflict and destruction.
