Argilac Durrandon

Argilac, also known as Argilac the Arrogant, is an unseen character in Game of Thrones. He is deceased when the series begins and has only appeared in "The Complete Guide to Westeros: House Baratheon" featurette. Argilac was the last of the Storm Kings, the rulers of the Stormlands since Durran Godsgrief, a legendary figure of the Age of Heroes and founder of Storm's End.

When Aegon the Conqueror invaded Westeros, he sent his commander and rumored half-brother, Orys Baratheon, to take the ancestral stronghold of the Storm Kings. Argilac met Orys' forces in open battle and was soundly defeated. Afterward, Orys took not only Storm's End and the Stormlands, but also Argilac's black stag sigil, his words - "Ours is the Fury" - and his daughter, becoming the first Lord Paramount of the Stormlands and the founder of House Baratheon.
