Star Ocean Wiki

Planets (惑星, Wakusei?) are celestial bodies that orbit stars. Throughout the Star Ocean series, one or more may serve as a setting for each game. However, voluntary travel between planets is not possible in any game other than Star Ocean: The Last Hope, as the party usually travels between planets as the plot progresses.

Planets are mapped according to their system (Sol System for Earth, Klaus System for Klaus III and IV, Arcura System for Expel), and sector (for example, Theta Sector englobates Earth, Roak and Energy Nede, while Gamma Sector englobates Ise, Lezonia and Vendeen). These sectors are a method of division of the Milky Way and go from Alpha to Zeta. They are also classified by development according to criteria stated in the Underdeveloped Planet Preservation Pact.
