There are tens of thousands of worlds known by humans in the galaxy they call New Eden66,856, to be exact, dispersed through 7,800 solar-systems.  There are also 2,500 randomly-accessible wormhole-systems.  Humans spent millennia reaching, colonizing, rebuilding, unifying, and warring between them… and still haven’t managed to notice how so many of them are hollow… and secretly connected via internal worm-holes of their own.

 

Backstory:

Set more than 21,000 years in the future, the background story of Eve Online explains that humanity, having used up most of Earth’s resources through centuries of explosive population growth, began colonizing the rest of the Milky Way. In turn, this expansion also led to competition and fighting over available resources as it did on Earth, but everything changed with the discovery of a natural wormhole leading to an unexplored galaxy named “New Eden”. Dozens of colonies were founded, and a structure was built to stabilize the wormhole that bridged the intergalactic colonies with the rest of human civilization, a giant gateway bearing the name “EVE”.

However, when the natural wormhole unexpectedly collapsed, it destroyed the gate. Cut off from the rest of humanity and supplies from Earth, the colonies of New Eden were left starved and disconnected from one another; some died out entirely.  This time was known on many of the New Eden colony-worlds as the galaxy-wide Dark Ages.

Over the millennia, some of the descendants of the colonists managed to survive and rebuild their own societies, but the memories and knowledge of humanity’s origins as well as their own from Earth and the Milky Way became lost (just as the ancient knowledge of their Earth-ancestors’ descent from the Elves and Angels/Valar had been lost due to similar cataclysms back on and around that world). Five major distinct societies rose to prominence from the stabilized colonies, each growing into interstellar spaceflight-capable civilizations. The states based around those colonies make up the five major factions in Eve Online: the Amarr Empire, the Caldari State, the Gallente Federation, the Minmatar Republic, and the Jove Directorate (this latter one seeming to have diverged and evolved distinctly from the other four, and curiously in-keeping with “the rule of primes”, such as how humans usually only teach four states of matter, ignorant of (or shy about mentioning/accepting) the fifth).

 

Planet Types in New Eden:

All the worlds in this region of the Universe are grouped into eight major categories.

  1. Barren:  There are 19,135 barren/rocky/’dead’ worlds in New Eden.
  2. Gas:  19,682
  3. Ice:  3,234
  4. Lava:  6,405
  5. Oceanic:  2,935
  6. Plasma:  1,489
  7. Storm:  5,337
  8. Temperate:  7,000

All of them can have colonies and other facilities on and around them (in orbit), the exception being the gas-giants, of course (which only have stations in orbit).
