Arc 6: Ragorlang is the 6th Saga in the W.I.T.C.H. comic series.
Summary[]
When Hay Lin stayed over at the Lyndons' home, she meets Karl and Tecla Ibsen, an elderly couple who appeared to have a connection with Eric's new school. Karl tells Hay Lin about the Ragorlang, a monster that absorbs the thoughts, the voices, and the sounds of its victims. Coincidentally, a few students at Eric's school are getting inactive as if they had lost their youthful strength. The same evening, Hay Lin gets attacked by a Ragorlang and was saved just in time by the other Guardians. Soon they discover who's behind the new threat: Tecla Ibsen. She wanted to be young and beautiful again and used her magical ability to conjure up and control the Ragorlangs, ordering them to steal the youthful strength of the teenagers by absorbing their thoughts and voices. The Guardians managed to defeat her and her Ragorlang. Unfortunately, Tecla returns, but as a frail, older woman, who can't summon a fully grown Ragorlang. Tecla brainwashed a magical girl named Erin, making her believe that the Guardians are the Ragorlangs and that it was their fault that her brother, Kader, went missing. At first, Erin uses her magic to make the girls hate each other while posing as an exchange student. She held Irma hostage with her mind-controlling power but released her when the Guardians helped her find her brother.
This saga also introduced a strange optometrist, named Folkner, who stationed himself in Sheffield to monitor the students' health. The Guardians found out that he's a Ragorlang hunter who wishes to hunt down Tecla Isben. She later regains full power due to leaked magics from Kandrakar and attacked the Guardians with a new pact of Ragorlangs. Despite being able to use the Shadow Heart against the Guardians, she was defeated when the last of her Ragorlangs was absorbed into a box created by Folkner. Obsessed with the dark power, Folkner unleashed the powers and became a supreme Ragorlang himself. He was later killed by the Guardians and was sucked into his own Ragorlang box at the end of the saga, and Karl and Tecla were both accepted into the Congregation of Kandrakar after admitting their mistakes.
