The Gwerian migration was the last major migration out of Shuul in the fourth era. The Yeula who left Shuul in this wave sailed East, landing in Nurfel, which continued to be their home well into the seventh era and beyond. The term "Gwerian" was used to refer to the people who descended from this migration, who eventually included the Halflings and Gnomes. The term was also used to refer to things created by those people, including their language family and the empire that spawned from their lands.
