And in the great palace of the Blade Empire, a crown touches the peak of its glory before it falls from its grace. Lush Von Blade was the royal crown prince of one of the greatest empires on the southern continent. He is loyal but betrayed.On the other hand, where even the Gods fear to set a foot on, a demon lord abides. His grace and cruelty have been unseen for centuries.
