Hidden from history and erased from every file, Y/n Hargreeves—Designated Number Eight—was Reginald’s most dangerous secret. Born with the rare ability of Soul Tracking, she could sense, follow, and locate any soul across timelines, universes, or even after death. Fearing her power would disrupt his plans, Reginald froze her in suspended stasis, sealing her away beneath the Academy before the rest of the siblings ever knew she existed.
