Magic is failing. Across the Magic Dimension, spells collapse mid-cast, portals tear open without warning, and the skies above Magix fracture with strange celestial storms. The ancient source of all magic — the First Star — is dying. As Alfea struggles to contain the chaos, the Winx discover that this isn’t an ordinary threat. The First Star was the original heart of magic itself, and its collapse threatens to erase every kingdom, every fairy, every spark of power in existence.
