Harken is a knight of Pherae, and former fiancee to Isadora. Harken served Elbert faithfully, after he had taken him in from his former liege's poor treatment. After Elbert's death, Harken took it upon himself to tear the Black Fang apart from the inside, much to the chagrin of Isadora when they would be reunited. Harken, atypical of the other knight characters of Blazing Blade, seems to hold immense self-loathing, from both his treatment at the hand of his first employer, and his helplessness at preventing Elbert's demise.
