Kailea Vernius

House Vernius is a fictional noble family from the Dune universe, though the family does not actually appear in Frank Herbert's work. Rather, they are featured in the prequel series Prelude to Dune (1999–2001) and Heroes of Dune (2008–present) by Brian Herbert and Kevin J. Anderson.

According to Dune: House Atreides, the family crest of House Vernius is a purple-and-copper helix.

At the time of the Prelude to Dune series, House Vernius is one of the great houses of the Imperium, the feudal interstellar empire that forms the backdrop to the Dune novels. This house is the ruling power on the planet Ix. The main industry on Ix is the production of machines that continuously test the bounds of the precepts set down by the Butlerian Jihad. The rival of House Vernius is House Richese, which also specializes in machinery, but doesn't create controversial machinery. The strongest ally of House Vernius is House Atreides; their friendship had begun when Earl Dominic Vernius and Duke Paulus Atreides had fought together in the Ecaz Revolt around 10,130 A.G.

Dominic Vernius had been a military ally to 80th Padishah Emperor Elrood Corrino IX in the Ecazi rebellion, around the time one of Elrood's concubines Shando Balut had given birth to the Emperor's illegitimate son (who is named Tyros Reffa, and secretly adopted by House Taligari). Dominic and Shando subsequently fall in love; tired of Shando but not knowing of her relationship with Dominic, Elrood grants her request to be released from his service. Dominic and Shando are soon married in 10,138 A.G., and Elrood is furious, "paranoid about what bedroom secrets Shando might be sharing with her husband." Dominic and Shando would later have two children together, Rhombur and Kailea.
