Fifty-eight years before the Fall of the Twelve Colonies, the Guatrau of the time lives and conducts business in Caprica City, relying on enforcers like Sam Adama. Years earlier, the Guatrau paid for law school for Sam's brother, Joseph Adama, who provides legal defense and other services for the Ha'la'tha. The Guatrau meets personally with Joseph to convince him to threaten then Minister of Defense Val Chambers. The Guatrau then promises Joseph that he is committed to finding the perpetrators of the MLMT bombing that had recently claimed Joseph's wife and daughter (CAP: "Pilot").
Some months later, the Guatrau meets with Daniel Graystone at the wealthy industrialist's behest. With the aid of both Adama brothers, the Guatrau enters into a mutually beneficial alliance with Graystone, offering to help him regain control of his company, Graystone Industries, in return for profit made from Graystone's newest venture — virtual avatars of dead people (CAP: "Unvanquished").
Despite his dealings with Graystone, the Guatrau is personal friends with Tomas Vergis of the Vergis Corporation (CAP: "Pilot", "Know Thy Enemy"). However, once Vergis discovers that the Ha'la'tha were behind Graystone's reappointment as CEO of Graystone Industries, he believes that the Guatrau would eventually have him killed, prompting him to kill himself instead (CAP: "Things We Lock Away").
Through his daughter, Fidelia Fazekas, the Guatrau later discovers that Joseph and Sam Adama are smuggling U-87 Cyber Combat Units to resistance fighters on Tauron. The pained Guatrau orders Fazekas to kill the Adama brothers — this results not in their deaths, but in the death of Joseph's only surviving child, Willie Adama (CAP: "The Heavens Will Rise", "Here Be Dragons"). The Adama brothers seek retribution for Willie's murder and, in order to avoid an all-out conflict with the Ha'la'tha, manage to convince Fazekas to launch a coup against the Guatrau. This coup results in the murder of the Guatrau during what was to be a meeting between the two parties, and Fazekas assuming the position of Guatrau herself (CAP: "Apotheosis").
- The name of the particular Guatrau featured in this article is never given. His surname is possibly Fazekas, as this is the surname of his daughter.
