The Xiou are a tribe in the Southern Tribelands of Arnasia in Authlanis. This is a very agricultural tribe and the most permanent settlers of all the Southern Tribes. They have amazing irrigation techniques, and spend most of their manpower on farming Zut, a grykonite-like vegetable that can be eaten fresh, cooked, or ground into bread.
They worship Arnasia the Widow Goddess through nightly ceremonies where they sing, chant, and dance, wishing the Light Bringer a solemn rest.
The Xiou are very peaceful, but highly territorial. Any wars that have been fought were for the saving of their land.
