Clanbook of the Highlanders, a traditional text.  The history and culture of the Five Clans of the Phoenix, who wage a war against the Duchy of Volta in Evendarr to reclaim their lost homeland.

A History of the Biata Race, By Jihaval Toron.  A book that claims to hold the history and culture of the Biata.  Since that people have little to do with me since I am a caster of Celestial Magic, I cannot vouch for the accuracy of this document, but it is a fascinating read.
