The Houses of Westeros are noble families that play a central role in the political landscape of George R.R. Martin's series, "A Song of Ice and Fire." Each house has its own sigil, motto, and unique characteristics, often tied to their ancestral lands. The most prominent houses include House Stark, House Lannister, and House Targaryen, each vying for power and influence. These houses are often in conflict, forming alliances and rivalries that shape the history of Westeros. The struggle for the Iron Throne, the seat of power in the realm, drives much of the narrative, highlighting themes of loyalty, betrayal, and ambition among the houses.
