Sarah stared at the contents of the time capsule. It had been found while excavating to build a new road. Inside, a collection of photographs, letters, and small trinkets. Her hands trembled as she picked up a photograph of a family.

She didn't know them. Yet, a knot formed in her stomach. Familiar faces, familiar smiles. The objects seemed to evoke a lost language. The letters were written in a script she recognized, but the words were a mystery.

She closed her eyes, trying to grasp at the pieces of this buried memory, this forgotten life. The world seemed to fade around her.
