The first half of the game is played mostly on Nadine, it is a paradise planet much like Haven and Earth. With foliage, water, breathable air and no weird rules. It's dominant species is humanoid, consisting of Elves of three varieties, Dwarves, Goblins, Halflings and as hinted at briefly, Saramarin Humans and Beroshian Bearmen at one point.
Galaxia is possibly one of the most developed Planets in the Origin Universe, with embedded politics, history, mechanics and rules very alien to human ideals. The Galaxion Empire call this Frigid sphere home, the copious blue coloring is caused by the lighting of their cities, which is the only light the planet generates, it's the power source that has made them feared throughout the galaxy, the lifeblood of the god of the universe, the galaxion Empire utilizes power from the Blue Sun itself.
An artificial planet designed and created by the Galaxion Empire, it's an entirely artificial and impressively sized postal planet capable of sending 'parcels' to any location in the Galaxy with the power of High Ordinance Cannons, it also serves as a refuge for survivors of Galaxion conquest. It's where Tac is located for the majority of the game.
While not a Planet, it could certainly serve as one... The Sovereign is the hegemonic flagship of the Galaxion Empire, commonly the Directorate are at the helm. It's larger than all of the other varieties of ships in the fleet combined and several times over. It contains several bays for Time Racers and refueling/repairing stations for ships of all Galaxion varieties, it itself generates Energy perpetually. It's very rare for a simple Galaxion Warship to be damaged to the point of combustion, the Sovereign is even tougher. It has enough Heavy Carapaced Plating to withstand a Blue Sun Energy Storm even when on emergency power. The Sovereign stands the tests of time and tribulation, it functions well beyond the Battle of Nadine.
The home planet of the Cloud Nymphs, the one race that even Blu isn't ashamed or scared of. The Planet has a Dark Core where-in dwells Shadow Pixies and other mysterious spectres. Typically the Cloud Nymphs and the Beneath choose to not mingle with each other in any fashion.
A digital planet which can't be landed on generically, you must instead proceed to the docking ring and take a digitransmaterializer to make contact with the planet's surface. This planet is home to the Bytepets and The Glitched, originally it was a Paradise Planet like Earth but while 'The Glitched' were testing virtual reality it caused the virtual world to become their world, though it's evident they didn't mind. They could easily undo it, but they don't want to.
This Planet also has a far more ominous purpose, something pertaining to a keeper of the gate.
Home Planet of the Dragonar, Wyrms and Galleons, the citizens of Draik are neutral and more often than not, are unwelcoming towards outsiders.
Home base of the Simian Space Pirates (SSP's), this Planet is one that is truly free, the inhabitants are typically neutral to outsiders who don't give them reason to carry a chip on their soldier. The populace is a jolly constitution of thieves, drinkers, pirates, smugglers and gambligants. They do what they want, whenever they want, at all times. The majority of the Space Pirates are Monkeets exiled or seeking refuge from Haven due to criminal acts, but any race is welcome among the space pirates if their teeth be gold, their avarice bold and their appetite like mold.
A lush jungle-laden planet of which Monkeets, Ratwring, Crocidilus and several other mammals call home. The Monkeets are the dominant species, often just called Monkeys (in slang) and have several lit towns dotted across the planet. It's common to find outsiders at Haven, largely due to it being run by a worldwide democratic union.
The Shattered Empire... It might have been a Paradise Planet at one stage but now it is all that remains of the Zirkovian Empire, among one of many planets the Galaxion Myriad have conquered. Despite the lack of a core the planet is still rampant with life, and some cities have survived the ruination.
The Prison Planet of the Ancient Ones, currently it's just a scenic walk about in game, given it's atmosphere as a Gas planet it's unlikely that anything mortal lives on it or anything immortal would choose to.
Yeah that's right, it's Planet Jupiter. That's all there really is to say about it.
The Angelic Pink Sun is the source of the Cloud Nymphs' power, the potent mystical energies have made even the Galaxion Empire far from game to assault the Cloud Nymphs, that hasn't stopped them from doing some shady things with the suns chosen, though.
The Heart and House of Origin, in this powerful star the creator dwells, this 'Sun' is more important than I care to let on. Suffice it to say it is an omnipotent star that also serves as a universal egg timer.
