Sarafine Duchannes is one of the main antagonists in The Caster Chronicles series written by Kami Garcia and Margaret Stohl.
She was portrayed by Emma Thompson, who also played Lesa in Hoodwinked!, Karen Eiffel in Stranger Than Fiction, The Woman in Lutins, The Yeti Elder in Missing Link and Baroness von Hellman in Cruella.
Being born in the cursed Duchannes family as a Natural, one of the most powerful Casters known in Caster world, she was not able to choose between Light and Dark. This eventually lead to her turning into a Cataclyst when her Sixteenth Moon revealed to her the path of Darkness. First trying (and failing) to fight off her Dark nature, the Dark soon took control over her in the same time Abraham Ravenwood was helping her grasping her power.
She eventually killed her husband Josh when he threatened to take their child, the newborn Lena, away from her fearing for Lena's safety around her. She eventually let the Dark totally and completely consume herself, ultimately becoming the "Darkest of all Casters". She also murdered Ethan's mother, Lila Evers Wate, a fact that she does not deny and almost brags about; saying how easy she was to kill. Sarafine is eventually murdered by Lena in the third novel Beautiful Chaos when she encircles her in a circle of fire. She attempts to trick Lena into freeing her claiming to have always loved her, but Lena, aware of her trickery and lies, allows her to die. She is then perished in the flames of the fire, suffering the same fate as her late husband John Eades did by her own hands.
In Beautiful Redemption, she helps Ethan in his journey by killing herself so he may return to the Mortal world- helping him defeat Angelus since, while she openly says she hates Ethan, she hates Angelus "more". Ethan, though, likes to believe a part of her genuinely wished to help Lena and him.
