Synopsis
Alex Boyer, a history teacher at Peelsbrook College, discovers that he is the descendant of King Arthur upon being able to lift the sword Excalibur. Now the rightful protector of the land, Alex is convinced by Nimue, the Lady of the Lake, to fulfill his destiny and protect his homeland from anyone who poses a threat to it. However, Alex has never been in a situation like this before and is infamously known for his weak will, which means he has much to learn and overcome if he wants to live up to his title.

Main

 * Alex Boyer/Excalibur: The descendant of King Arthur and wielder of the magical sword Excalibur. He gets anxious in tough situations and is infamous or his weak will, both of which he must overcome to live up to his potential. His sword grants him several superhuman abilities as well as having several mystical powers of its own.
 * Nimue, Lady of the Lake: Alex's mentor and the original person who gave Arthur the sword. She is a highly gifted magic user and has nigh-infinite knowledge due to her countless years alive.

Supporting

 * Donna Boyer: Alex's sister who is a journalist and wants her brother to be more outgoing. She herself is very assertive and charismatic, though later events in the series reveal she is far less confident than she seems.
 * Cathy Boyer: Donna's daughter and Alex's neice. She is very young and hyperactive, likely due to her age.
 * Knights of Avalon: A group formed by Alex later into the series' run to serve as his Knights of the Round Table.
