Before the coming of men, the lands of Westeros are inhabited by a mysterious race of diminutive humanoid creatures known as the Children of the Forest, giants, and other magical creatures. A human ethnic group, the First Men, invades Westeros across the land-bridge from the east, bearing weapons of bronze. In a futile attempt to end the invasion, the children use magic to shatter that land-bridge, creating the island chain known as the Stepstones. However, the First Men are able to fight on, leading to generations of warfare over the land. The First Men are more numerous, larger, stronger, and more technologically advanced than the Children, who try to resist the invaders using their magic. It proves unsuccessful, however. The First Men gradually push deeper and deeper into Westeros, establishing hundreds of petty kingdoms.

After years of warfare, the First Men and Children of the Forest come to a standstill and finally agree to a peaceful coexistence, signing the pact of The Isle of Faces. This pact gives the First Men dominion over the open lands and lets the Children keep control over the forested areas. In time, the First Men adopt the worship of the Old Gods of the Forest.
