Priva was the smaller of Altiria/Anarris' two moons and was the brightest natural satellite in the planet's night sky.
History
Priva was first colonized by the Altiri from Altiria/Anarris around 500 BBY. The colony, named Shalla after a goddess of peace worshipped early in Altiri history, was originally a research station and eventually became a starport for receiving offworld visitors.
