Dragon of Stone

House Valaerys, like the Targaryen's and Velaryon's, had survived the Doom of Valyria, caused by the Fourteen Flames. At the beginning of the Targaryen dynasty, House Valaerys was considered a lower house despite their fair skin, silver hair and glowing blue eyes that were unique to them and them alone.

They were different then the others that descended from Valyrian blood. But as time passed, they grew to be one of the most powerful Houses in Westeros.

House Targaryen ruled the skies.
House Velaryon ruled the seas.
But House Valaerys challenged both their claims with their wild spirits, wreaking all sorts of havoc on land, in the sea, and in the clouds.

Most of the realm wondered... what would happen with a Valaerys being betrothed to a pure Targaryen?
