Before the Karthmeres came in what is known as the third wave of migration, Thyllanor was inhabited by the native Andorasi, those who are now the Wetlanders, Gardorians, and Moonlytes. The second wave was brought about by the Tegrushkin or a culture similar to them, and resulted in settling Frostfall, which gave rise to the Northmen. Finally, the Edrossi wave came, which included the Thyllanorians as well as the Shoremen (The Edranians came in their own wave some time between the second and third waves).
