Jayber Story in The First Descendant

Are geniuses born or made? A natural engineer, there are many hypotheses about the origin of Jayber’s ability to wield Arche specialized in electronic warfare. One hypothesis claims that the infectious disease he suffered during his childhood stimulated his cerebral cortex, leading to a dramatic increase in intelligence. Another one claims that the drug administered to treat the infectious disease was actually an experiment conducted by the Magisters to mass produce Arche… Despite the unfounded rumors that continue to go around to this day, he himself had no desire to learn the truth. The reason being, as merely a unit in the war, the origin of his ability was unimportant to him.
