The Noble Houses of Westeros

The Great Houses are the most powerful of the noble houses of the Seven Kingdoms. They exercise immense authority and power over their vassals and territories and are answerable only to the King of the Andals, the Rhoynar, and the First Men, with the exception of House Stark, which rules over an independent kingdom.
The Great Houses are often distinguished by their sigils, words, and notable members. House Stark, for example, is known for its direwolf sigil and the words "Winter is Coming." House Lannister, on the other hand, is recognized by its golden lion sigil and the words "Hear Me Roar!" House Targaryen, the family of the former ruling dynasty, is identified by its three-headed dragon sigil and the words "Fire and Blood."
As the story of the Seven Kingdoms continues to unfold, the fates of the Great Houses remain uncertain. New alliances will be formed, old enemies will be resurrected, and the balance of power will constantly shift as each house struggles to maintain its position of authority and influence.
