Obsidian

Obsidian, or the Obsidian Circle, is a planet in the Magic Dimension. It appears in the Winx Club Movie. It's the planet of ultimate evil. In this dimension, all the evil creatures live. Somewhere in this place, there's a huge sea of solid rock, in which the inhabitants of Sparks were captured. On top of a rock, the king was standing, turned to stone. He tried to get his sword, in which the queen was captured. Behind were three caves with faces, in which the Ancestresses lived. Obsidian also has a guard, Mandragora, Witch of the Insects. If someone who is not evil enters Obsidian, he or she is lost in the power of evil. When the Winx, without Musa, enter Obsidian, they all except for Bloom, get lost. The four fairies then get to see their biggest fear: Layla gets attacked by her Morphix, Flora gets attacked by dead plants, Tecna gets a headache because her brain computer `crashes´ and Stella disappears. When Obsidian gets destroyed, the witches are free, and at the end of the movie they fly through a hall, to the Trix. They say they will possess their bodies. In the second Winx Club Movie, they all together disturb the party at Alfea.
