The Flame of Clarity (Swedish Klarhetens Låga) is a novel set in the W.I.T.C.H. universe. It was written by Maud Mangold and, to date, does not have an English translation.
A weird shadow can be seen in the photo Taranee just took with her new camera. She has strange dreams about a small peculiar man in a sponge-shaped hat, and about a blue flame that will soon extinguish.
Taranee believes someone needs the W.I.T.C.H. girls help! Someone wants her to save the dying flame but it turns out that the rules of a normal flame don't apply. If it extinguishes, the time will freeze and if the king can not see into the future, evil powers can get into the country. Some signs implies that this has already happened...
Excerpt from the book
Slowly raised Taranee her hands and let the fire carefully flow forward. She felt that the fire wasn't afraid. It fluttered to and grew smaller. Taranee let more fire come out. And a little bit more, and a little bit more. The Flame of Clarity retrieved slowly. It shone clearer and stronger now. At first it was blue, then it turned into light blue and white.
