Magic Dimension

The Magic Dimension, referred to as the Magic Universe in some episodes, is the universe where most of the adventures of the Winx Club take place.

Overview
The Magic Dimension is a dimension located very far from Earth that contains different magical realms and planets where magic is everywhere and it is inhabited by many magical creatures. The Magic Dimension is also called Magix from the name of the realm found at the center of the dimension.

The foundations of all the realms of the Magic Dimension are the three pillars found in the Infinite Ocean.

Other Dimensions
There are many other dimensions that are linked to the Magic Dimension but are separate from it. These are:
 * Relix is where the ultimate power of the Universe is found. The key to the Relix dimension is the Codex, which is divided into four pieces.
 * The Omega Dimension is a frozen world used as a prison for the Magic Dimension's worst criminals.
 * The Golden Kingdom, where the Water Stars were placed, because they would clash with the Dragon Flame and cause chaos if they remained in the Magic Dimension. The door of the Golden Kingdom is found at the base of the Red Tower found in The Barrier.
 * The Obsidian Dimension is the realm of absolute evil and the birthplace of the Ancestral Witches. The Obsidian Circle is its gate and the dimension was destroyed by the Winx.
 * The Infinite Ocean, where the Pillars of the foundation of all realms and the Emperor's Throne, are found. Only Sirenix possessors, Selkies and the Guardians of Sirenix can open portals to enter the Infinite Ocean.
 * The Legendarium World, which requires the Ancestral Wands to enter.
