The Other Me in the Mirror Is a Wanderer

"In a primitive tribe stricken by drought, a hunter dies from wild boar wounds. His widow blames Tiffany, an outcast orphan with a bald patch on her crown. Persuaded by the old prophet, the tribe brands her cursed. Chieftainess Keña sentences her to three days without food or water in a cave, then execution by fire. Near death in the cave, Tiffany finds a strange glowing mirror stone. It connects her to her modern counterpart — also named Tiffany Moreno, with the identical bald spot. Modern Tiffany once witnessed this mirrored phenomenon before. She tells the ancient Tiffany calmly: she survived with the same bald patch, and the ancient Tiffany will live too."
