Vindex was the great-grandson of a Chelaxian nobleman who fled the country during the Chelaxian civil war. His great-grandfather fled as far as he could go, taking work as a caravan guard and eventually ending up in the Tien city of Goka, where Vindex's grandfather, father and then Vindex grew up.
Vindex had a hard childhood, with his father and his grandfather dying when he was young. He had some trouble fitting in, with his distinctively foreign Chelaxian features, and had few friends as a boy, frequently suffering from the bullying of his peers. He pushed himself, training with his Grandfather's Naginata, working odd jobs to stay alive while he dreamed of no longer being at the bottom of society. Eventually, one of his odd jobs caught the attention of a member of the Pathfinder Society, and he was admitted on a field commission.
