Is this small paragraph worded in the correct way?

As Dorn grew up, the wizard had him trained to be a fighter in the arena and enchanted the golem parts for improved efficiency. After he had become a veteran arena competitor, Dorn found a way to kill the mage and escape from the city. Once Dorn claimed his freedom, he began working as a mercenary who specialized in jobs that required him to kill dragons and other dangerous beasts. Over the years, Dorn allied himself with the arctic dwarf ranger Raryn Snowstealer, the halfling scout Will Turnstone, and Pavel Shemov, a human priest of Lathander, to form an elite group of hunters who operated around the Moonsea region.
