The Greyjoys are a prominent noble family in the fictional world of Westeros, created by author George R.R. Martin in his series, A Song of Ice and Fire. They rule the Iron Islands, a group of rocky islands off the western coast of Westeros. Known for their seafaring skills and fierce independence, the Greyjoys follow the ancient motto, "We Do Not Sow," reflecting their belief in raiding and pillaging rather than farming. The head of the family is known as the Lord of the Iron Islands, and the most notable member is Balon Greyjoy, who seeks to assert his family's power during the events of the series. His children, including Theon Greyjoy and Yara Greyjoy, play significant roles in the unfolding political conflicts. The Greyjoys are characterized by their rugged lifestyle and strong adherence to their traditions.
