The six-part series followed the 1953 book in great detail and was filmed in various locations including Peak Cavern, Haddon Hall, Bakewell, Derbyshire and the Duchy of Lancaster.
Rilian disappeared 10 years earlier after weeks of searching the woods near Cair Paravel for the serpent who had killed his royal mother, the Queen.
Rilian then confesses that he destroyed the Silver Chair, and the Witch then attempts to put all three travelers under the same spell, blotting out any memories of Narnia or Earth, but her magic fails to work on Puddleglum.
The next day, Glenstorm the centaur takes the children to Cair Paravel to witness the return of King Caspian.
However, Caspian is fading fast by the time he returns to Cair Paravel, and dies shortly after meeting Rilian, who is then proclaimed King of Narnia by Trumpkin.
