A notorious prisoner of Harrowstone near Ravengro, Sefick Corvin's crimes earnt him the title of Father Charlatan: he pretended to be a priest of any number of churches in order to swindle gullible worshippers out of money through false miracles and healing. He worked alongside Sczarni accomplices, who would murder to cover up any exposure of the charlatan.
Though Corvin was no murderer himself, the churches against whom he blasphemed sought and won the greatest sentence possible for the criminal: imprisonment in Harrowstone, wrapped in chains depicting the symbols of the wronged churches. Corvin was removed to Harrowstone in 4661 AR, along with four other notorious criminals, and died that same year in the great fire that destroyed the prison.
