Who is Aloana Streggi from Chapterhouse: Dune and what is their importance?

Aloana Streggi is an Intermediate, Third-Stage Bene Gesserit acolyte with curly hair, round face, and wide mouth, Streggi is assigned to map the desert's encroachment on Central for Reverend Mother Superior Darwi Odrade. Having prepared a progress report, Streggi clears her throat several times and then talks to the feared Mother Superior at dinner. Odrade is impressed and makes her a special assistant to carry around on her shoulders the Bashar Miles Teg in a ten-year-old's body, faster than his little legs can go. During the Battle of Gammu, Streggi is at a loss in the command center when not serving as Teg's "horse." In the subsequent Battle of Junction, Streggi is slain when the Honored Matres pull out their secret weapon. Teg is taken captive.
