This pillar is made from green glass like substance and its shaped like a huge needle, standing and keeping balance on smaller piece that is on the ground. It is surrounded by eight smaller but same shaped crystals. Its seal is blue.
When the seal is taken, it causes Magix to shake and structures to come down with lack of balance.
When Tritannus steals the seal of the Pillar of Balance, the whole magic dimension loses its balance and starts shaking.
As Darcy and Stormy steal the Singing Whales, Musa confronts them and villains flee. The sound of the whales is horrible until Musa uses the Voice of Sirenix using her mother's lullaby to free them. The Winx then use convergence to restoring the balance of all of the Magic Dimesion.
