It carries the weight of their fall from grace, a stain that cannot be erased. And when mixed with demon blood, it becomes even more terrible." She paused, her gaze distant as if reliving painful memories. "I've seen it myself in Luca's children. Nate, your half-brother, tortured a cub mutant beast when he was only five years old. The glee in his eyes as he did it... It was unnatural, a glimpse of the darkness festering inside him."
