What to Expect (Plot, Tone, Themes)

  • The story will be more personal & character-driven than large scale political warfare. It focuses on Dunk (a knight without great wealth) and Egg, his squire who is secretly a prince.  
  • Knights, tournaments, noble houses, dragons being recent memory — so the magical or legendary elements are still strong in the background.  
  • Since it’s only 6 episodes, the season will be compact; likely each episode has high production value but careful pacing.
