Although the story's main focus is on Merlin and Arthur, there are 6 main characters who are the true players. They are as follows:
Merlin
Child of prophecy, Merlin has the ability to use magic with no study, since birth. Born in the farming village Ealdor, of the kingdom Cenred, and knowing very little of his father, Merlin grew up alone with his mother. Fearful his gift would be found out living in such a small village, his mother sent him to live in Camelot City in the Kingdom of Camelot. Merlin's adventures truly begin as he lives with Gaius, the ex-Sorcerer now Court Physician, in Camelot castle.
Gaius
Formerly a powerful and wise sorcerer, now Court Physician, Gaius serves his King Uther as loyaly now as he did back in the days where magic was common place in Camelot. Gaius now serves as a secret tutor, and part time father to Merlin, as the boy finds his destiny. Although Gaius is well versed in magic, he refuses to use it under even the most dire of circumstances, as is law in Camelot.
Uther
King of Camelot, he became leader when he freed the land of its plague of magic. Since then, magic has been outlawed in all of Camelot, and is punishable by death. Although Uther once fought along side those of magic, he now will not hesitate to execute anyone involved with it. Fearful for the life of his son Arthur and ward Morgana, Uther rules Camelot with an iron fist.
Arthur
Prince of Camelot, Arthur has grown up privileged his entire life. The best food, the best schooling, the best fighting, he has it all. As a member of one of the Camelot Knights, Arthur leads with honor and grace, and is said to wed the Lady Morgana, Uthers Ward, when he is of age.
Morgana
Lady Morgana is Uther's Ward, the daughter of a great house now fallen. Uther took her in when her father, a good friend, passed away. Morgana suffers from severe headaches and nightmares and is often treated with herbs and tinctures from Gaius, although to little effect. She is also often comforted by her best friend and maiden, Guinevere, who most affectionately call Gwen.
Gwen
Daughter of the Upper Quarter blacksmith, Gwen has been a hand maiden her entire working life. She is lucky to serve only the Lady Morgana, whom she has become friends with over the years. Gwen is compassionate and kind, and wishes Prince Arthur would display those qualities if he is to become king.
