Spore Universe

The Spore Universe is a boundless and infinite universe composed of galaxies. One can't travel between them, and they are like parallel universes in the way that they all share similar characteristics (a center of galaxy guarded by the Grox, and a replica of the Personamon's own solar system) but unlike in the way that they exist in the same space. Intelligent life abounds in all galaxies, and each Personamon has control over one galaxy, and just a few species. Each galaxy has arms and a core, each arm/core (the core is completely dominated by the Grox) has solar systems, each solar system has a star and some planets, and certain planets have life. Life in the Spore Universe evolves in stages, each one being a higher state of social and biological complexity. Each galactic black hole leads to a paralell plain which is home to Steve, who grants the power to make barren planets lush (The staff of like) to any who enter it. Billions of years ago the Grox created inter-galactic travel, colonizing every single Spore galaxy, Steve cutting off the routs, leaving each galaxy ruled by slowly evolutionarily diverging clans of Grox. This universe was contained in the Digitechtrine, before it was destroyed in the Last Great Purge. Go here if you want to start interacting with it.
