Gurhal Star System
From PSU Cyril Wiki
Gurhal is the name of the solar system in which Phantasy Star Universe takes place. It is comprised of the three planets Parum (blue), and Neudaiz (green), Moatoob (orange), and also includes the man-made space station known as the Guardians' Colony.
The three planets are shown in the Phantasy Star Universe logo. Each planet 'belongs' to one of the Races (the exception being the Casts, who have no planet) as a result of a treaty signed 100 years before the start of the Story Mode, which ended an inter-racial war in the system.
