The Finding of Excalibur Chapter III
I will save you King Arthur!
King Arthur journeys to find adventure and comes upon a castle. There he meets Lady Annoure. She tries to get him to stay with her by offering him the ability to rule over her people. He is an honorable knight so he says no and stays loyal to his people.
This makes Lady Annoure angry so she throws him in her prison. In the morning she comes to see if he has changed his mind. He still stays honorable so she throws him out.
This is Excalibur. With it you shall never die of your wounds.
He continues on his journey and comes to a fountain. There he meets a man named Sir Pellinore. Pellinore says that if Arthur wants to pass they must fight. Pellinore almost kills Arthur but Merlin comes to save him.
In the battle with Pellinore, Arthur's sword breaks and he refuses to go back to his kingdom without one. Merlin takes Arthur to the Lady of the Lake. Arthur gets on a boat and goes out to get his new sword.
Merlin tells Arthur that the sword is called Excalibur and that he will not die from his wounds as long as he has it. On their journey home they meet back with Sir Pellinore and he becomes a knight at the round table
