From ancient times, peace and order reigned in the kingdom. Until the Dark Lord came.

He seized power with false promises, and then forcibly destroyed all who rose against him. Darkness penetrated the souls of the kingdom's inhabitants, draining all joy and thirst for life, turning people into soulless shells.

Princess Eterna is the only one who can end the Dark Lord's spell. But she was captured and imprisoned in the Black Castle - an old fortress that was turned into a prison.

Will there be desperate souls able to save the princess and the entire kingdom?
