After the Ascension of House Atriedes, under Paul Atreides, Wensicia joined her father and his entire family in exile on Salusa Secundus. As an attempt to re-gain Hasimir Fenring as an ally, Shaddam encouraged his daughter to marry Dalak, which she did; and subsequently produced a male heir, little Farad'n.
Dalak was a weak personality, and Shaddam considered him very effeminate; and Dalak was not in high honor in the former Emperor's presence. To pad his coffers, Dalak sold Corrino family heirlooms off-world, when Dalak was supposed to be making contact with Hasimir.
When Dalak returned to Salusa Secundus, Shaddam confronted him with the knowledge of his treachery. Though Dalak denied the charges, Shaddam confronted with a pistol, and encouraged Dalak to commit suicide, which Dalak refused. When an argument ensued between Bashar Garon and Shaddam as to whether or not Garon should shoot Dalak, Wensicia came forth.
Wensicia grabbed the pistol from Garon, and fired three shots directly into Dalak's heart, killing him instantly. Though the event occurred directly in front of the toddler Farad'n, Wensicia promised a dead Dalak that she would embellish the image of his father to the little child.
