Gunseng did not acknowledge Araskin as his natural son, though he never denied it publicly. Muertana explained to Araskin that his condition was due to the genetic shortcomings of Gunseng, whom she loathed, and she reared the ostensible na-Baron herself, poisoning his mind against his father.
Gunseng's preference for Vladimir cost him his life: at a state banquet, Araskin murdered him and attacked Vladimir. That night, Muertana was strangled by Vladimir.
In Prelude to Dune Vladimirs parents are named Dmitri and Victoria Harkonnen instead of Gunseng and Muertana Sarobella and he has a retarded half-brother named Marotin instead of a retarded brother named Araskin.
