Vincent was born in Hiberia in 161 AYZ to Edith Apothik. He was her second child, being preceded by Oscar Murray, the product of an affair with a ship captain several years earlier. Vincent's parentage is uncertain, though it is assumed his father was Giorgio Bacci, who married his mother shortly after his birth.
Giorgio and Edith became involved with the Cult of Vormund when Vincent was very young. When Giorgio lost his job, he turned to another cult member, Kirk Callow, for help. Kirk allowed the family to stay with him at his pawnshop. Giorgio had a drug problem and, after some "friends" he had invited over trashed the shop, Kirk threw him out. Edith followed him, taking her children with her.
By 164, the family was living in the sewers underneath the city. Giorgio was often absent for extended periods of time, enough that he considered himself estranged from his family. Without his knowledge, Edith and Oscar fell ill and were quarantined by the sewers' other inhabitants. Vincent, being a small child, went with them.
Dagda Vormund arrived in Hiberia along with several of his closest followers. Hearing of Giorgio's state, they went down into the sewers to help. There they found Edith already dead, Oscar on death's doorstep, and Vincent sick as well. They brought them back to Kirk's shop and attempted to nurse them back to health, but Oscar didn't last long. Vincent survived, but was left blind by his illness.
With Giorgio's mental health deteriorating as a result of his addiction, Vincent was more or less adopted by the cult. He traveled with them and was present when Vormund, his son Ethan, and his lieutenant Drusus Rolfe were arrested by the Rhinehart police - Giorgio having thrust Vincent into Rowan Renard's arms before fleeing at the first sign of danger.
Rowan took Vincent with him to the city of Tyr, where he left the boy in the care of Lord Gavin Zosimus, another cult member. Gavin took Vincent on as his ward and raised him alongside his own children, Laura and Galahad.
Vincent is described as a svelte young man, with wavy black hair and blue eyes. He has an easy smile, is well groomed, and has a faint Hiberian accent combined with that of a highborn Tyran.
