House of Festil (fictional)

The House of Festil is a fictional royal family in the Deryni series of historical fantasy novels by Katherine Kurtz. Throughout the novels, various members of the family occasionally serve as antagonists of the plot, most notably in Camber of Culdi, Saint Camber, The Bastard Prince, Deryni Rising, and High Deryni. The family is a junior branch of the House of Furstán, the royal family of the Kingdom of Torenth, and the Deryni heritage of the family is juxtaposed by the human heritage of the House of Haldane, the main protagonists of the series.

Festil Ferencz Furstán is the progenitor of the House of Festil, born as the second son of King Kalman II Furstán of Torenth. Eight decades before the events of Camber of Culdi, Festil launches a surprise attack on the neighboring Kingdom of Gwynedd and succeeds in overthrowing King Ifor Haldane. He is crowned King of Gwynedd shortly thereafter, and quickly establishes a new government that essentially replaces the human peerage of Gwynedd with his own Deryni allies. Festil's actions establish much of the social and political landscape that is depicted at the beginning of Camber of Culdi, a cultural setting which is markedly different from that depicted in Deryni Rising. After a reign of over seventeen years, Festil dies at the age of 59 in 839. He marries once, fathering nine children, and he is succeeded by his firstborn son and heir, Prince Festil II.

Festil Avgust Fyodor Furstán-Festil is born in 800, and he succeeds his father upon the throne of Gwynedd at the age of 39 in 840. His reign lasts for over eleven years, until he is killed when his carriage overturns on journey from Valoret to Rhemuth. Festil II dies at the age of 51 in 851. He marries four times, fathering six children, and he is succeeded by his firstborn son and heir, Prince Festil III.
