What is "wensicia"

Princess Wensicia is a fictional character and member of House Corrino from the Dune universe created by Frank Herbert. She was introduced in Herbert's 1976 novel Children of Dune—the first hardcover best-seller ever in the science fiction field—and appeared decades later in the 2008 novel Paul of Dune by Brian Herbert and Kevin J. Anderson.

As established in the appendix of Dune (1965), Wensicia is the third daughter of the 81st Padishah Emperor Shaddam IV and Anirul, a Bene Gesserit of Hidden Rank. Her oldest sister is the Princess Irulan; her three other siblings are sisters Chalice, Josifa and Rugi. Wensicia accompanies her father into exile on Salusa Secundus after he is deposed by Paul Atreides in Dune.

Wensicia is portrayed by Susan Sarandon in the 2003 miniseries Frank Herbert's Children of Dune.
