What is "anirul"

Lady Anirul Sadow-Tonkin Corrino is a fictional character and member of House Corrino in the Dune universe created by Frank Herbert.

A Bene Gesserit of Hidden Rank and wife of the 81st Padishah Emperor Shaddam IV, Anirul is the mother of Shaddam's five daughters, the Princesses Irulan, Chalice, Wensicia, Josifa, and Rugi, and is the grandmother of Farad'n. Anirul is referred to only three times in Herbert's 1965 novel Dune (and only once by name), but is a major character in the Prelude to Dune prequel trilogy (1999–2001) by Brian Herbert and Kevin J. Anderson.

The Dune Encyclopedia (1984) by Willis E. McNelly provides an extensive, alternate biography for Anirul. The Encyclopedia notes that Anirul had been compelled to comply with the Sisterhood's breeding program by way of a residual poison administered by Gaius Helen Mohiam, and refers to Anirul's distant, icy relationship with daughter Irulan and revulsion for the "malicious" Wensicia.
