The Greyjoy family is one of the Great Houses in the fictional world of Westeros, created by author George R.R. Martin. They rule over the Iron Islands and are known for their seafaring culture and fierce independence. The family motto is "We Do Not Sow," reflecting their reliance on raiding and piracy rather than traditional agriculture. The head of the Greyjoy family is known as the Lord of the Iron Islands. Key members include Balon Greyjoy, the patriarch, and his children, such as Theon Greyjoy and Yara Greyjoy. The Greyjoys are often portrayed as proud and rebellious, embodying the rugged spirit of their maritime homeland.
