From the moment when astronomers realized what the galaxy was, it was commonly referred to, typically in poetry, as a sea of stars. When put in this regard, the discovery of the other Sea of Stars is a far more interesting occurrence. Not that it is boring to begin with. Somewhere in a remote part of the Antarctic Ocean, there is a sea where the water is the same dark shade as the night sky, where pokemon from space such as Clefable and even Jirachi and Deoxys visit (or live in) when pining for home.

And in this sea are a galaxy of shining Staryu with glowing red, blue, or yellow cores, a horde of pokemon as numerous as the stars. Aircraft and flying-type pokemon which fly over these Staryu often find themselves confused, unsure which way is up and which is down, and crash into the sea where their wrecks are used as homes. And yet, as it is the closest thing to space one can see without becoming an astronaut, many adventurers seek it out anyway.

Indeed, there is little to separate Staryu from the traditional depiction of stars, which resemble this pokemon far more than the real thing. But while the cores of stars slowly explode both in reality and popular culture, those of Staryu instead regenerate, healing the pokemon of even its worst injuries.
