From the Back of the Book:
The many-headed Hydra slithers in the Harrowmarsh on your western border. The Sphinx prowls its blasted lands, breathing a venomous wind upon the lush savannah. The Harpy's birds of prey circle in coastal salt breezes, raiding laden ships. It seems as if Binsada, your land of simple, nomadic cattle herders, is hemmed in by monstrous enemies on all sides.
Binsada is a realm where honor means more than wealth. The ruler of this domain must maintain the status of the royal family while not offending those from other highly placed lineages. Foremost in the regent's thoughts must be retaining the loyalty of her first lieutenant, Vorduine, and controlling the ambitions of her cousin, Prince Daoud--without his knowledge, of course. This regent must have a cunning mind, a flair for the dramatic, and an honorable heart.
This BIRTHRIGHT domain sourcebook is designed for players who wish to take the role of queen of Binsada. It may also be used by players portraying noble, vassals of the regent, or adventurers from this domain.
