The ancestors of the Miqo'te made their way to Eorzea during the Age of Endless Frost, traversing the frozen seas in pursuit of the wildlife upon which they subsisted. Adaptation to a hunting lifestyle has fashioned them with a keen sense of smell, powerful legs, and a tail which provides them with exceptional balance.

Miqo'te are known to be very territorial, and many individuals tend to lead solitary lifestyles, particularly males. The few Miqo'te who have made the transition to life in Eorzean society are predominantly female.
