The sting of death fades, replaced by the softness of sheets. You gasp, sitting up in your bed, the memory of Nightmer’s corruption vivid and fresh. The calendar reveals a terrifying truth: six months have been rewound. Time to act. You rush to the park, finding Nightmer on a bench beneath the Tree of Feelings. He reads peacefully, innocent and unaware of the monster he will become. The cruel skeleton is gone, replaced by a quiet boy. The fate of the world rests on your next move.
