Tecla Ibsen looked like a nice old lady, living peacefully with her husband Karl in Open Hill, the town where Eric Lyndon and his family moved. Karl Ibsen was teaching history at the school where Eric's father works. When Karl was younger he traveled the world and he knows many legends and stories. Karl and Tecla were keeping a terrifying secret: Tecla can create a monstrous shadow, called Ragorlang.
The Ragorlang is a creature that can devour the energy from humans and transfer it to the body of its creator. Tecla used the creature to devour the energy of the young students that were learning in the Open Hill's school, and Karl helped her to get her hands on them by tricking them to follow him.
When Hay Lin came to Open Hill, she met Karl and Tecla Ibsen in Eric's house. Karl told her the legend about the Ragorlang, and in the same evening she got attacked by a Ragorlang, but the other Guardians saved her. Next week Will and Hay Lin were again in Open Hill, and this time Karl tricked Hay Lin and brought her to his wife. Then Tecla realized that Hay Lin was not an ordinary girl, because of her energy, which made Tecla years younger. She planned to steal all of Hay Lin's energy, but was defeated by the Guardians.
She then attacked a nomadic tribe of magic people who had settled down in an island on Earth and kidnapped a young girl with mental power, Erin Peyton, and sent her after the Guardians, saying her that they were the ones who sent the Ragorlangs after their people. Tecla's plan fails again because W.I.T.C.H. managed to show Erin that Tecla was the real culprit. She and her brother help the girls before leaving to another world.
Tecla was left very weak, but she managed to restore her power and became more powerful than ever by absorbing a part of Kandrakar's magic that flowed into Earth by accident. She became younger, created Ragorlangs with the power of elements and sent them against the Guardians, but they defeated them, recovered the stolen magic and Dr. Folkner stripped Tecla of her Ragorlang, but he unexpectedly decided to fuse himself with all the Ragorlang he captured over the years, becoming a threat bigger than Tecla.
Tecla didn't give up, however, she returned to Heatherfield, knowing that the Ragorlangs were attracted by the energy of the young people that would attend Karmilla's concert. She infiltrated into Folkner's house to get her Ragorlang back, but when Folkner (now a big ugly Ragorlang-like creature) threatened all the city and took Karl's energy when he arrived to save his wife, Tecla understood she was wrong to use an evil power to get her young back, she already lived her life, and now all what she really needed was her husband's love. She revealed the Ragorlang's weakness to light to the girls, who combined their power along with Folkner's trap box, trapping Folkner and the Ragorlangs forever inside it. And the end, Tecla and Karl are offered by the Oracle to stay in Kandrakar, and both accepted.
