Vicente Valtieri was a male Breton who resided in the Dark Brotherhood's Cheydinhal Sanctuary. He and his family suffered because of the high prices and taxes during the War of the Red Diamond. Vicente was a long serving member of the Dark Brotherhood, having been a brother for over 300 years. He and several other Breton members of a Mages Guild expedition to Morrowind was attacked by a clan of vampires. Vicente survived while his friends were butchered. He did not escape unscathed though, he was bitten and turned into a vampire. He hunted in secret for over a 100 years until the Dark Brotherhood found him. Valtieri quickly rose in the ranks until he became an Executioner. He could advance no further. Vicente then became an administrator of the Cheydinhal Sanctuary. He was assigned to be the overseer of a new family member that Lucien Lachance had found. This new family member was none other than Bendu Olo, the Hero of Kvatch. Bendu quickly completed all the contracts Vicente could give him until eventually Ocheeva, the main adminsitrator of the Cheydinhal Sanctuary, was given the position of being Olo's overseer. Several weeks later Olo returned as the instrument of the Black Hand, and was performing the Ritual of Purification. Vicente and all his fellow brothers and sisters in the Cheydinhal Sanctuary were swiftly hunted down and killed by Olo.
