The Cabal are a militaristic, Romanesque race of physically imposing, heavily armored "space turtles", they appear to have enslaved a separate race, and enlisted them in their military, known as Psions, who are smaller, more agile, and have some sort of mentally activated powers. Goal appears to be conquest of habitable locations, such as Mars. Industrious to the core, they pulled Mars' moon Phobos out of orbit to mine for resources, and/or to use as a weapon. Archetypes include : Psions, Legionnaires, Phalanx, Centurions, and Colossus. Units : Sand Eaters- Dust Giants- Siege Dancers- Blind Legion- Ice Reapers. The Fallen are a nomadic race of four-armed "space pirates", they appear to be like us, in the way that they experienced a collapse of their civilization, and now roam the stars in their Ketches, scavenging for anything that might give them more Golden Age information, or point them to more life-giving ether. They dissolved into different Houses sometime after their collapse, the ones I know about are: House of Devils- House of Kings- House of Exiles- House of Winter- House of Wolves. Archetypes include: Dregs- Vandals- Shanks- Captains- Servitors. The separate Houses appear to hold each other in contempt. The Hive is the antithesis to the Light, they long to consume it and leave darkness in their wake, their hatred transcends emotion, and it shows, not much is known to me about the Hive other than they do seem to be guided by a more powerful dark entity, as the epilogue to one of the Moon missions states. Factions : The Hidden Swarm- Spawn of Crota- Blood of Oryx. Archetypes include: Thralls- Acolytes- Knights- Wizards- Ogres- Shrieker- Cursed Thrall. The Vex are machines that are robotic, and yet also organic, each Vex unit is part of their greater algorithm for thought process. They existed, exist, and will exist in a future to come. They transcend physics and time, attempting to bend them to their will, they deploy units according to an algorithm among their thought processes, to best suit their environment, or the situation. However, they are not perfect, as the Virgo Prohibitive are losing the war against the Cabal on Mars, some postulate that the Virgo Prohibitive just isn't the right algorithm for the situation on Mars, and the greater Vex minds will adapt and change accordingly. Factions: Hezen Corrective- Hezen Protective- Virgo Prohibitive- Sol Divisive- Sol Primeval- Sol Imminent- Aphix Invasive. Archetypes: Goblin- Hobgoblin- Harpy- Minotaur- Praetorian- Oracle. Feel free to add to this, I probably missed a lot, and post theories if you want to. I'll also add more, as I learn, and will add stuff about places, weapons, etc.
