House Havilliard has been founded by Gavin Havilliard, after defeating the Valg King Erawan and marrying Elena Galathynius of Terrasen, daughter of King Brannon Galathynius. As a wedding gift, Gavin received the lands of the future Adarlan. He selected Rifthold as his capital along the banks of the fast-flowing Avery River.
By the time Throne of Glass takes place, Adarlan had became an empire under the reign of Dorian's tyrannical father, conquering new territories, including Melisande, Terrasen, Fenharrow and Eyllwe. The house is not loved by the inhabitants of their colonies, especially the Terrasiens, who as said, would have had the king's head placed on the top of the gates of Orynth, if only they has an occasion to do so.
