The Tree of Life holds the positive and negative balance of magic and initially grew in the Pixie Village, till the Pixies seemingly moved their village somewhere still near the Tree, from where they, along with Ninfea, guard it. Inside of it flows all the magic of the Magical Dimension, containing both positive and negative magic which co-exist in harmony, and the tree glows and grows thanks to this balance between the positive and negative energy within it. Each branch corresponds to a world, and each leaf to a fairy.
It first appears in Season 2 as a flower-like plant from which the Pixie babies and Pixie baby animals are born.
Season 4EditThe Tree of Life was shown in the second episode of Season 4 this time as a real tree. One of its branches corresponds to Earth, and was empty for a long time, with only one leaf remaining, standing for Roxy. When the Winx defeated the Wizards of the Black Circle in the episode Attack of the Wizards, new leaves started growing again on it showing that Earth was ready to welcome new Fairies.
The Tree appears again in the second movie, where it is shown that half of the Tree contains positive energy, with leaves and flowers standing for Fairies, and the other half contains negative energy, with curled branches looking as if they were withered for Witches.
The Pixies are responsible for the safety of the Tree of Life. The protective energy of the Tree of Life, which feeds the Magical Barrier, defends the city from external threats.
The Tree of Life is covered with MagicPops, magical globes that contain positive energy which looklike sparkling enchanted dust.
When a Pixie uses its Talent for a good purpose, to serve the well-being of the community, it receives a MagicPop from the Tree of Life. Discovering their talents and obtaining the MagicPop is a special moment in the life of Pixies and an important moment of their growth as they discover their positive qualities.
