The following is the list of principal fictional characters from the children's animated series Princess Gwenevere and the Jewel Riders (also known as Starla & the Jewel Riders outside of North America). The series follows the quest of a young princess of Avalon, Gwenevere (Starla), and her friends, Fallon and Tamara, to find and secure the scattered enchanted jewels and thus stop the evil Lady Kale from taking over the kingdom, restore harmony in magic, and bring the banished wizard Merlin home. In the second season, the Jewel Riders receive more powers and new costumes to battle Kale and the mighty Morgana for more magical jewels that too need to be kept out the grasp of dark forces.
The titular trio of teenage Jewels Riders consist of Gwenevere / Starla (voiced by Kerry Butler in the first season and Jean Louisa Kelly in the second season), whose Special Friend is the winged unicorn Sunstar (Deborah Allison), and her friends: Fallon (Allison), riding Moondance the unicorn (Barbara Jean Kearney), and Tamara (Laura Dean), who in the second season gets the "zebracorn" Shadowsong (Henry Mandell). Each of their Jewels has different magical abilities and their own colors and corresponding gemstones of various powers, also allowing them to communicate with their animals.
Gwen and her friends are aided by the Merlin's talking owl named Archie (John Beach Voiceguy). In their missions, the Jewel Riders are also sometimes aided by the Pack, led by Gwen's aspiring boyfriend Drake (Voiceguy). In the second season, a relatively major character comes into the story: Ian (Bob Kaliban), the man-wolf prince of the Forest of Arden who falls in love with Gwen.
The series' main antagonist is initially Lady Kale (Corinne Orr, who also voices Kale's good sister Queen Anya), Gwen's villainous aunt. She is aided by her dragon Grimm (Peter Fernandez) and a duo of dweezels (dweasels), the small minion creatures named Rufus and Twig (Voiceguy and Mandell, respectively). The prime enemy in the second season is Morgana (Allison), with Kale reduced to her insubordinate sidekick.
Gwenevere (named Starla in the European versions) is the titular main character of the series. When the story begins, Gwenevere (Gwen) is a 16-year-old Princess of magical kingdom of Avalon. A daughter of Queen Anya and King Jared, Gwen lives in the Crystal Palace inside the castle of New Camelot. On coming of age, she must prove herself worthy for the role of Queen of Avalon. After the first episode, Gwen becomes the leader of the Jewel Riders at the Friendship Ring Ceremony where she is given sacred Sun Stone, which is the jewel of light, a powerful gem that creates colourful rainbow effects from the bright sun light. Gwen is romantically attracted to Drake, the leader of the Knights of Avalon (the Pack) but finds his brashness annoying. Later, she falls in love with a wolfman prince called Ian. Gwen is good-natured, and she has some of the traits of her famous namesake such as courage, a strong will and impulsiveness. However, she also has a fiery temper and can sometimes be snobby, spoiled, prissy and pretentious. She is also obsessed with fashion and beauty and loves to dress up in fancy dresses and attend royal parties. In "Dreamfields", Gwen and her wicked aunt Lady Kale share each other's dreams and they compete for a Jewel and Gwen must rely on her friends to help her fight off the corrupting nightmares of the Dark Stone (she also briefly becomes "evil" again when Gwen falls under Kale's hypnotic spell in "Fashion Fever"). In the second season, a fortune teller with a Wizard Jewel tells Gwen her destiny is to be a future ruler of Avalon. Motivated by this vision, Gwen gains the confidence of the Jewel Riders and then leads them to victory over the forces of darkness. In the end, Gwen manages to overcome Kale once and for all and then turns the Dark Stone to good and joins it with her Sun Stone, which allows the Jewel Riders to successfully challenge the power of Morgana.
