The Duke of the Ancient WyrmEpisode 7

Pure-blood dragon Karen Valery was betrayed by his adopted sister Isolde, who wiped out his entire clan. Left for dead in the frozen northern plains, he awakened his black-gold ancient dragon bloodline and fought for seven years to earn the title Duke of Ancient Dragons. After regaining his memories, he returns to Nolen State with unyielding power and unleashes his vengeance at his enemy’s engagement banquet, only to uncover tangled political conspiracies behind the massacre of his kin.
