Hugor of the Hill

Hugor of the Hill is an unseen character in Game of Thrones. He is not expected to appear in the show, being long dead by the time it begins. He was the legendary first king of the Andals.

Biography
According to legend, the Father pulled down seven stars from the heavens and set them upon the brow of Hugor to make a glowing crown. The Maiden then brought him a girl as supple as willow, with eyes like deep pools, whom Hugor declared he would take as his bride. The Mother made her fertile, and the Crone foretold that she would give him forty-four mighty sons. The Warrior gave strength to their arms, and the Smith made a suit of iron plates for both of them.
