Tula Harkonnen: the Harkonnen who wed and slew an Atreides
Tula Harkonnen was an early member of House Harkonnen and a sister of the Bene Gesserit. On the orders of her elder sister, Valya Harkonnen, she married Orry Atreides and murdered him on their wedding night to avenge their slain brother.
Tula Harkonnen was an early member of House Harkonnen and a sister of the Bene Gesserit, born of the Harkonnen line exiled to the cold world of Lankiveil. A younger sister of Valya Harkonnen, she became the instrument of her sister's long vendetta against House Atreides: she married Orry Atreides and killed him on their wedding night, one of several Atreides deaths she carried out in revenge for the killing of their brother Griffin Harkonnen. (Mentats of Dune; Navigators of Dune)
Origins and the Bene Gesserit#
Tula belonged to House Harkonnen during the era when the family held no high station, its fortunes bound to the harsh world of Lankiveil. She was a sister of Valya and Griffin Harkonnen. Like her elder sister Valya, Tula entered the Bene Gesserit and was raised in the disciplines of the Sisterhood, training that made her a capable and unsuspected agent in the wider quarrels of the noble Houses. HBO's Dune: Prophecy adds an uncle, Evgeny Harkonnen, to the family. (Mentats of Dune; Dune: Prophecy)
The murder of Orry Atreides#
The Harkonnens carried a bitter feud with House Atreides, sharpened by the death of Griffin Harkonnen, and Valya set herself to avenge him. Tula became the means of that revenge. She drew close to the Atreides on Caladan, in the years before that family had risen to the rank of a Great House, and married Orry Atreides. On their wedding night she killed him at her sister's command. She did not stop with her husband, killing others of the line as well, among them Shander Atreides, who died on Caladan by her hand. That wedding night also left her carrying a secret son, and his return years later drives the plot of Dune: Prophecy. (Mentats of Dune; Dune: Prophecy)
In time the Tula Fjord on Lankiveil was named after her, fixing her name to the homeworld of her House. (Navigators of Dune)
