Memory shards—crystals formed upon a person’s death, holding fragments of their life. These shards are prized for their ability to impart not just knowledge, but affinities—subtle but potent skills or traits honed by their original owner. For centuries, the world has functioned on this system: farmers inheriting the memory of fertile hands, traders buying shards for an affinity for negotiation, and even nobles secretly consuming the memories of soldiers to gain an edge in combat.
