Sinners came in all shapes and sizes, and not all of them were born from the union of an Anomaly and a human. Some began as ordinary humans who inherited the power of an Entity like Mirai, or they could be something entirely different.
Eduard Dickson, Louis's uncle and Gustaf's younger brother, was another devoted scientist and Esper. Though never as powerful as his older sibling, he worked tirelessly alongside Gustaf to shield humanity from the horrors of the Dimensional Labyrinth and the Grievances that hungered to consume the world and wipe away all traces of human history.
Ten years ago, he volunteered for an expedition into the First Layers of the Dimensional Labyrinth. His team fell to an ambush by a swarm of powerful Entities commanded by a Grievance, and they disappeared for months. Gustaf sank into profound depression, certain his brother was lost forever. He became even more emotionless and withdrawn from his family.
