Magic Mirror

The Magic Mirror is a legendary creature/object that appears in Season 6.

History
According to Selina, there was a queen who used to wield the mirror. Its legend was mentioned in the Legendarium:

"Once upon a time, there was an evil queen, who possessed a mystical, magic mirror."

Appearance
It is a golden mirror. When it is activated, purple flames appear in it.

Season 6
In "Queen for a Day," Selina unleashed it in Stella's room to turn her evil, so she could let the Witches in the Palace of Solaria until Brandon accidentally attacks the mirror and breaks the curse.

Magical Abilities
The mirror has the ability to charm anyone by adoring them and telling them that their beauty is the greatest among everyone. Once the user touches it, it immediately darkens his/her heart and bewitches them, turning them evil.
