HARKEN is a female construct and a killer in Die Of Desth. She originates from the dimension of FableHaven and was later transported to Earth. She is the last of her specific type of construct, a survivor of a lethal auditory ecosystem.

In her native state, Harken is a towering, gaunt, yellow mechanical figure with elongated limbs, her silhouette imposing compared to Civilians and other entities. Her head features a single large, closed eye dominating her face, flanked by two metallic pins, with a third pin serving as a neck joint. Her torso is asymmetrical and misshapen, with the bottom right section seemingly sheared away and the left side curving downward.
