Empusa

Empusa is one of the two secondary antagonists (alongside Mormo) of the 2007 film Stardust.

She was the youngest of the three Lillim sister witches.

History
At the age of seventeen, Empusa's oldest sister, Lamia, became very ill and was presumed to die. Unable to watch her suffer, Empusa attempted to use magic to cure her, but failed. After days of searching for a solution, the middle sister Mormo came across a mystical woman who had fallen from the sky. After bringing the woman home, Empusa (knowing what the woman was) killed the woman and cut out her heart. After feeding the shining heart to her sister, Lamia had later awoken more beautiful and healthy as ever. The woman was Yvaine's sister, Ingrid.

From that moment forth, the witches planned to forever rule the Kingdom of Stormhold by gaining their immortality from the hearts of fallen stars. However, after years of living inside of a world of dystopia, came an army of men lead by a forceful warrior whom had succeeded at overpowering the evil witches. She was killed by Prince Septimus.

Powers & Abilities:
Though not as powerful as her oldest sister, Lamia, Empusa was still a formidable witch in her own right. Examples of powers she displayed through witchcraft were:
 * Divination: Like every witch, Empusa had the ability to gain insight into a question or situation using an occult standardised process or ritual, which was usually either casting a set of runes, or examining animal entrails. In fact, it was highly likely that her and Mormo's divination abilities were more advanced than Lamia's, for Lamia regularly relied on her sisters' divination for answers when her own divination failed.
 * Pyrokinesis: Empusa had the ability to create, shape, and manipulate fire - she heated up Septimus' sword to the extent where he had to drop it, and conjured streams of fire to attack him.

Appearance
Due to her advanced age and excessive usage of magic for evil purposes, Empusa's true form is an ancient decrepit hag, but she still looked younger than her elder sisters.

However, if she eats a Star's heart, Empusa would regain her youth and beauty, transforming from an ancient ugly crone into a beautiful young woman with long auburn hair and ocean-blue eyes.

Personality
Being the youngest sister, Empusa was shown to be almost completely deferential to Lamia, though she did not hesitate to snap at or argue with her when irritated to breaking point. She was as insatiable for youth and beauty as Lamia, and has no qualms over using her powers to try to kill those who cross her path.
