Earth-4664

Earth-4664 is a attempt of Draft227 to create a single, giant, shared universe between multiple works of science fiction, as well with the aid of any potential idea of his friends and fellow Crossroaders. It is a huge, yet very detailed and lore rich combination of Halo, Mass Effect, Star Trek, Starcraft, Warhammer 40k and, possibly, Star Wars (where possible). This is one of Draft's most ambitious projects.

Origins
Once upon the first eons of existence, in 100,000,000,000 BC, there was a race known as the Leviathans roamed through the galaxy, giving protection to the races they deemed honored.

Not much time later, the beings known as the Xel'naga arrive at the Milky Way galaxy upon escaping from a deadly conflict in their own galaxy, called the Light of Chaos. Wishing to start a new life, the Xel'naga begin working on seeding life through the new galaxy they encountered, effectively conceiving the Protoss, Forerunners and Humans. Upon discovering the Mass Relays build by the Leviathans, they acknowledge the existence of another sentient race, and by their own beliefs, attempt to hunt them all of Leviathans, so they can build their empire without interference.
