Alia Atreides (Dune Films)

*Bit speculative here, but Alia as she should appear as played by Anya-Taylor Joy in future films*

Alia Atreides (November[1] 10191 AG - 10219 AG), also known as Saint Alia of the Knife and later Coan-Tean ("the female death-spirit who walks without feet") to the Fremen and called Hawt the Fish Monster on the outer worlds, was the posthumous daughter of Duke Leto Atreides I and his Bene Gesserit concubine Lady Jessica. Born on Arrakis, she was the younger sister of Paul Atreides.

"The Fremen see her as the Earth Figure, a demi-goddess whose special charge is to protect the tribes through her powers of violence. She is Reverend Mother to their Reverend Mothers. To pilgrims who seek her out with demands that she restore virility or make the barren fruitful, she is a form of anti-mentat. She feeds on that strong human desire for the mysterious. She is living proof that the 'analytic' has limits. She represents ultimate tension. She is the virgin-harlot - witty, vulgur, cruel, as destructive in her whims as a coriolis storm."
