The blade of the Thirteenth has risen - cursed and unforgiving. The tale of the most dutiful Sir Percival, the Right Hand Knight of King Arthur, surges back to life in the unassuming Spanish city of Manresa - fabled location of Castle Corbenic and the venerable Fisher King. The city and its people appear unharmed by the ill fortunes that plagued the world at the hands of Niobid Damasichthon, but the source of its protection raises fears amongst the Sacred Band and those descendants of the Round Table. A delve into history and the swell of the Iberian Empire at the hands of Morgan le Fay through her control of the Palladium and Necklace of Harmonia unlocks secrets behind the rise and fall of the infamous Armada and subsequent dawning of the Elizabethan Golden Age - all not being as it seems when compared to the familiar forging of empires over the many centuries. A poisonous legacy endures, a legacy potentially unmatched by even the most formidable of relics, Excalibur.
