The planet Roak is one of the major planets in the Star Ocean series, seeing how it is involved in all the games except Star Ocean: A Second Story. The planet was bombarded with a biological weapon that petrified the entire populace in Star Ocean: First Departure. The planet has three major continents, Muah, Astral, and Silvalant. Muah is the less developed of the three continents. Astral is the more militaristic of the three continents, being the homeland of the Highlanders. Silvalant is the most climatically diverse. With the southern end always filled with the colors of fall, and the north being covered in snow. The three races of Roak are the Fellpool, Highlanders, and the Featherfolk.
