Kingdom Key Ω

The starting Keyblade for Lily. She wields it in a manner like Aqua, but prefers a balanced mix of magic and melee instead of Aqua's more magic-heavy style. It sports the same design as the other Kingdom Keys, but instead of gold or silver, this Keyblade sports a white blade and a red guard.

Lore
When Lily meets up with Anthony at the Keyblader's Library, he reads to her from a book which describes how each Kingdom Key fits into the workings of the universe. She finds out that her Keyblade was made in order to eradicate Darkness from every world and every person. However, she doesn't fulfill this purpose because she knows it would cause an imbalance between Darkness and Light.
