Service in Battle
A once loyal servant of Padishah Emperor Elrood IX, he served admirably in the Ecazi revolts early in his term. It is during this time of civil strife that he developed a close friendship with Duke Paulus Atreides of Caladan.
After the war his fief was expanded by the Padishah emperor to the Alkaurops system and became a popular and welcome guest to the Imperial court, balls and other events. There he met the Emperor's concubine, Shando Balut. Although Elrood IX was now a widower and did not sleep with any of his concubines, his male pride was hurt. When Shando finally left the emperor's service they married, earning Elrood's undying enmity. Dominic had the habit to treat the Emperor "cordially", as an equal.
His House on Ix came up with a new Heighliner design with more capacity. This required less flights; however Imperial tax was based on the number of flights rather than on the amount of cargo; the Heighliner redesign therefore resulted in a substantial reduction in income for House Corrino and evoked once more Elrood IX's wrath. The Emperor threatened him to break the agreement with the Landsraad and proceed with an inspection to Ix to investigate whether Ixian scientists develop illegal thinking machines in violation of the Butlerian Jihad and repression against his suboid working class.
Fall and Death
In 10153 AG the still vengeful emperor sponsored a suboid revolt and Tleilaxu invasion. During the revolt, Shando was injured by a maula pistol trying to protect Kailea. The couple went to a secret security chamber, where his son Rhombur and his guest Leto of House Atreides were waiting. They told to the children that House Vernius would go renegade, and Duke Paulus Atreides sent a rescue mission for the three heirs.
The Earl was forced to set up bases on Salusa Secundus and Arrakis. His children were protected on Caladan and his wife fled to a remote region of the Imperium where she was eventually executed by Sardaukar forces.
After many years he decided that he would use the family atomics to bomb Kaitain, repeating the fate of Salusa Secundus. After contacting the water merchant Esmar Tuek, he was betrayed by him and Sardaukar forces surrounded his Arrakis base. In the end he detonated a stone burner and took a large number of Sardaukar with him.
