“Knightfall” goes inside the medieval politics and warfare of the Knights Templar, the most powerful, wealthy and mysterious military order of the Middle Ages. The series goes deep into the clandestine world of this legendary brotherhood of warrior monks to learn who these knights were, how they lived, and what they died believing. With the historical and ruthless downfall of the Templar Order on the horizon, season two focuses on themes such as power, redemption, revenge, betrayal, family, and ultimately an epic war between church and state. Hamill joins the cast as new character Talus, a battle-hardened Knight Templar veteran and initiate master who is tasked with preparing the next generation of men to proudly wear the iconic red cross on their chests and become “God’s Executioners.”
