Calian the Chooser is one of the Heroes of the Horn. She is sister to Shivan the Hunter; both of whom are only born at the end of an Age. It was suspected that Elayne Trakand was pregnant with Shivan and Calian, but The Wheel of Time Companion states in the entries for each that they were born before the beginning of the Last Battle and Elayne had not yet given birth.
She rides with a red mask.
Calian is a parallel of the Hindu goddess Kali. She is an alternate form or aspect of the Divine Mother Parvati or Durga. In this form she is goddess of chaos and destruction, symbolizing the destruction of the previous Age, and is today considered as a goddess of time and change, symbolizing her role in bringing a new Age. She is revered as Bhavatarini - literally "redeemer of the universe". She is also represented as the consort of the god Shiva, who is the parallel to her brother, Shivan the Hunter.
