"After all, damn it all, we can't have the boys running' about all day like hooligans--after all, damn it all? Ought to be having' a first-rate eddication, at their age." (pgs. 9-10) This is one of the main ideas that sets up the whole novel. Sir Ector values education, and he wants both of his boys to have a good education. They need a new tutor, which then leads to Merlyn and his lessons.
"This is my tutor, Merlyn. I went on a Quest for him." (pg. 37) When Wart was searching for Cully in the forest, he runs into Merlyn by his cottage. Merlyn then offers to be Wart's tutor to which Wart accepts. They go back to Sir Ector, and Merlyn begins his lessons with Wart. This is another main idea of the story.
Throughout the story, Merlyn changes Wart into many different animals including a goose, an ant, a fish, an owl, a hawk, and a badger. He learns a different lesson through being each different animal. This is all in preparation of him becoming a future king.
"I shall crave the privilege of being the very first of your subjects to address you with it--as my dear liege lord, King Arthur." (pg. 209)
"Whoso pulleth out this sword of this stone and anvil, is rightwise king born of all England." (pg. 197) Wart goes in search of Kay's sword. While walking through the forest, he spots the sword in the stone. He thinks it's just a war memorial, so he attempts to pull it out. Soon after, the animals gather around and encourage him to pull it out. On the third try, he pulls it out with no trouble.
"He saw that his dear guardian was looking quite old and powerless, and that he was kneeling down with difficulty on a gouty knee." (pg. 206) Wart finds out he is now the King of England, and Sir Ector and Kay are now below him. This is shown when they kneel down to him. Afterwards, Sir Ector asks Wart to make Kay his seneschal. He receives many gifts from the people of Sir Ector's castle and various animals.
Merlyn visits Wart at the castle, and explains how everything came to be. He states that his real father is King Uther Pendragon, and that he, Merlyn, brought him to Sir Ector when he was an infant. Merlyn then calls him King Arthur, and Wart asks him to stay.
