Fallen: One of the first civilizations touched by the Traveler, this species was on the brink of ruin. However, after the Traveler revived the Fallen, the Darkness chased it away. The Fallen have been hunting it down ever since, trying to bring it back to their world. Hive: This faction IS THE DARKNESS. They are the reason the Traveler is always running. They wish to destroy the Traveler, and harvest it's energy for themselves. Vex: They are the creators of the Traveler, simply trying to bring it home, like a lost dog. After all, evidence suggests that they both are THOUSANDS of years old, and both machines. Cabal: They originally weren't involved in anything up until after the Collapse. Then they noticed many planets were empty, seemingly unaware of the Traveler's presence. However once life was discovered, they decided to stay and fight.
