Within Cardia Beckford's hazy memories, she can recall her father Isaac and the home where she lives alone, feared as a monster by the townsfolk—for in her body, she carries a deadly substance. Embedded in her chest by her father, the eternally beating heart—also known as Horologium—has the capability to produce infinite power. However, it also makes her skin destroy anything it touches.
