927 AD. The Killer-Blade Army has toppled the ruling dynasty, plunging the kingdom into chaos. The only remaining heir, Prince Jung-Hyun is living in exile, unaware of his family's dark fate. Still loyal to the dynasty, the beautiful and deadly warrior Soha sets out to find Jung-Hyun and guide him to become the great leader he was born to be. But with the Army's greatest assassins and the criminal underworld hunting them, Soha and Jung-Hyun are swept into an explosive, non-stop battle of swords, wits and bloodshed as they fight to reclaim the fallen throne.
