Planet Styx, known as Stream (惑星ストリーム) in Japan, is a mysterious planet located in the Beta Sector, where the Time Gate is located. Other than this, the planet is a barren wasteland, with little to no areas of interest. However, due to the sole fact that the Time Gate is located on Styx, the Pangalactic Federation has prohibited all access to this planet.
Story
Star Ocean
Ronyx J. Kenny escorts the party to Styx, with the intent of using the Time Gate, even though he knows he risks court martial. Styx is visited once again, when the party members from the past are seen home.
Star Ocean: Till the End of Time
Fayt Leingod and the party travel to Styx with the interest of using the Time Gate to access Fourth-Dimensional Space. However, the planet is heavily guarded by the Executioners, but they manage to get past them and access the Time Gate.
Sophia Esteed's power of Connection manifests shortly after arriving at the Time Gate. She uses her powers to reveal the Time Gate's true purpose, opening a portal to 4D Space that the party uses, emerging from an Eternal Sphere terminal in Arkives.
Dictionary Entry
(Star Ocean: Till the End of Time)
Part 1
A mysterious planet that has been declared a prohibited zone under Federation law, together with the region of space surrounding it for five light years in all directions. While the space surrounding this planet is outside the borders of the Pangalactic Federation, it is said that countless Federation battle-class ships are stationed in the area. Despite the lack of information, rumors among the general population abound, including whispers that the planet is the entrance to the Daemonium, or that an ancient, extremely powerful civilization sleeps there in stasis--but these are mere guesses.
Part 2
A mysterious planet containing the remains of an extremely ancient civilization. One of the ruins on this planet is a mysterious device known as the Time Gate. Although it is thought that the Time Gate is a time machine, and that it enables travel through time, very few details are known about this device.
(Star Ocean: Integrity and Faithlessness)
Though no one knows exactly how ancient the supposed former civilization on this enigmatic planet is, what little evidence there is suggests that one did exist. To whit, on the terrestrial body stand ruins that allegedly hold remarkable potential. According to second-hand sources familiar with researchers who have been there, those who activate the power latent within them will be able to transcend both time and space.
To ensure that no one abuses the shrine's power, the Pangalactic Federation keeps it under strict surveillance, allowing only scientists to set foot upon its sandy surface.
Trivia
- In both Star Ocean: Integrity and Faithlessness and Star Ocean: Anamnesis there is a mysterious desert place that has all the appearances of being the planet Styx. The mysterious structure appears to be a Time Gate or somehow an interface for the Fourth-Dimensional Space.
