When civil unrest in the empire in 1 AA reaches a boiling point, prompting slave revolts across the continent, the Dukedom of Meloir struggles to keep itself together as imperialists face both chimera uprisings and a rogue Templar order spreading chaos under the leadership of an enigmatic dark knight calling himself "The Raven."
While Meloir's Grande Armée works contingently with Royal Army soldiers to suppress the chimera rebels, Duke Andri Morin Duval, of the great House Duval, commissions the Templar Brotherhood of Semyaza to combat the rogue Brotherhood of Addelum. He tasks the Templars with the arrest of the infamous "Raven", so he can be made to stand trial for crimes of sedition.
