Lucy Pevensie
Like her brother Edmund, Lucy, the youngest of the four Pevensie children, has been to Narnia before and speaks wistfully of it. Returning is therefor somewhat of a dream come true for her. Although she is given many considerations by the others on account of her being a girl, this is really out of manners or gallantry and not necessity, as Lucy is brave and feisty, and just as able to fight in battle as the boys. She is loved and revered by the Narnians. Lucy steps up to do the right thing even when it is frightening, such as going upstairs in the Magician's house to find the spell that will make the Duffers visible again. Lucy has the closest relationship with Aslan of all the children and he is the most fatherly of her. She sees him far more often than the others. She is also in awe of him and the mere vision of him in the spell book with a frown on his face prevents her from saying another spell aloud even though she wants to. Lucy is kind and nurturing and even wants to help Eustace when he is being insufferable.
Edmund Pevensie
Edmund has grown into a fine young man since his first visit to Narnia and his first priority is to protect his sister throughout their adventure, even though she really doesn't need protection. He is a decent outdoorsman but sometimes lacks the skill of thinking ahead. He loves being in Narnia and relishes the opportunity to take part in the voyage and the battle. Although he likes Caspian and recognizes him as King of Narnia, he also expects Caspian to recognize the authority of Edmund's older brother Peter who was the first King of Narnia and Edmund does not take kindly to Caspian's flexing of his monarchical muscles. Edmund is forgiving of Eustace because he actually behaved in a far worse way during his first visit to Narnia yet was forgiven and redeemed, and so he wants to give Eustace the same chances.
Eustace Clarence Scrubb
Eustace is cousin to the Pevensie children and at the beginning of the novel this fact seems to be their terrible misfortune because not only is he a bully but also insufferable and rather a baby. He is interested factual study and doesn't think there is purpose in anything that cannot be catalogued or studied. He is a very unkind child and makes fun of the Pevensies reminiscing about Narnia. At the start of their adventure he is the archetypal nightmarish English tourist who considers the rest of the world savages, and he does not hold back his feelings which are largely ungrateful and peevish. He is a very spoilt and pampered boy with no fighting spirit. He immediately starts a feud with Reepicheep and is annoyed when the others side with the mouse rather than with him. Eustace is turned into a dragon on the island which ends up saving him as when he becomes a boy again he is much nicer and makes a great effort to be the kind of person another person would like to spend time with. He also starts to do small acts of courage and bravery for the first time and is a much-changed person by the novel's end.
King Caspian
King Caspian of Narnia is the lived King who rules benevolently from Cair Paravel. Occasions he forgets that the Pevensies ruled before him and can get carried away in exerting his authority over them. He is courageous and brave, a good leader and a proud Narnian who is keen to defend the honor of his country and his people. He is really the driving force behind the expedition to find the missing Lords sent out by his father and he does not rest until the Lords are found and the mission complete. By the end of the novel it is also clear that he wants to secure Narnia's safe future and extend the boundaries of what the Narnians have already discovered.
Reepicheep
Reepicheep is one of the bravest characters in the group. He is a mouse but has the heart of a lion; in fact he is more combative than a lion and always ready for a good argument or fight. He never shies away from danger and is the group's best strategist and tactician. Reepicheep is not the instigator of the feud between Eustace and himself; this is clearly the boy who is both verbally and physically abusive of the mouse. Reepicheep does not take Eustace's nonsense lying down and makes sure the others are aware of the reality of the situation and not just Eustace's version. He is true and reliable and therefore trusted. Despite his chippy nature Reepicheep is a loyal friend and is incredibly kind to Eustace when the boy has become a dragon, staying up with him all night, talking and generally offering solace.
Aslan
Aslan is the constant God-like character who appears in each of the Chronicles of Narnia. He is a huge and imposing lion with strength and beauty but also authority. He is benevolent and kind but also a harsh teacher when he feels it is warranted. He is very fatherly towards Lucy and his presence reassures her at the Magician's house. He speaks to Lucy like a friend although she reveres him as a prophet or teacher. He is the guide to the children even when he is not physically present, his face appearing in the spell book acting as a deterrent to Lucy when she wants to read more spells aloud. Aslan is an allegorical figure representing God.
The Magician
The Magician is an old man who has turned the Duffers invisible and has the impossibly difficult task of ruling an island filled with incredibly stupid people who believe they are right all the time and also believe that he is an exploitative ruler whom they need to outwit. They never outwit him but outwitting them is not much of a challenge. He is a kind and generous man who uses his magic for good purposes. He is also very good at using magic to make meals that consist of the favorite foods of each of the people eating.
Captain Drinian
Drinian is the Captain of the Dawn Treader and is both a good sailor and a strong leader which makes him a successful Captain. He makes sure the men he captains are treated fairly and in turn they repay him with hard work and loyalty. Drinian seems to hold Reepicheep in high esteem and will take his advice about everything and follow it even if it is the opposite of what he actually wants to do.
Ramanadu
Ramanadu is a magician who fell to the earth as a falling star, true to the legend of how magicians and sorcerers come to exist. It is he who has put the enchantment on the Narnian lords that has made them sleep and only he can break the enchantment. At the end of the novel we learn that Caspianreturns to his island and marries his daughter, and together they rule Narnia well and benevolently for many years.
