[b]edit[/b] Please go to this forum post, I'm still getting likes on this and due to information given after posting this I have updated my opinions. https://www.bungie.net/en/Forum/Post/89722085/0/0 It's not filled yet but will be hopefully by tomorrow. [b] end edit[/b] Here's what I think is the most likely. This includes information read and thought of on my own. The darkness is truly evil, it corrupts all that it touches. It has touched the hive and the fallen. The cabal do not follow the travelers light, but they also don't follow the darkness. The vex worship the darkness as it is the most powerful form of darkness (more on the specifics below) Going from the enemies as we meet them. [b]fallen[/b] The fallen were civilized creatures. they needed their defenses, but they were less oriented in battle. The fallen we face are of the once Nobel houses, the rest have died due to the corruption of the darkness. This is primarily why they aren't really battle ready. The darkness affected their entire planet ruining it and causing them to flee, but they were not untouched by it's corruption. They begin to degenerate into uncivilized bloodthirsty creatures in a quest for a new world to inhabit. [b]hive[/b] The hive were uncivilized creatures who lived in a world of what most would call magic. Their anatomy and sciences come across as impossible feats of magic, but are just as I said anatomy and sciences. The darkness quickly corrupted them causing them to flee as well. Crota led them to the moon. They had a long journey and became heavily corrupt, crota became known as a God and was worshipped. They took the moon and burrowed deep inside it, until one day the humans in the midst of their golden age came across them and started a war. The hive would not be pushed out of another home. [b]vex[/b] The vex were created by the precursors, these are vex like creatures seen in the undying mind strike. They only still exist in the black garden, a world in flux with time. The vex were formed by the corruption of darkness, this is not to imply precursors are peaceful or against the existence of the vex. In the story you come across the darkness as it's being worshipped by the corrupted precussors (vex) and attack it, wounding it dearly and sending it to flee. This was technically before the darkness corrupted the hive and therefore before it corrupts the fallen. More on this later on I want a certain timeline shown. [b]cabal[/b] The last to be touched by darkness, still holds most of its sanity and pursuits. The cabal were conquers, going from planet to planet crushing the inhabitants. The cabal were a gadfly accident. Going to the ruined planet of the hive they were corrupted by the remnants of darkness. They set out onto the trail that the darkness requests following the hive, fallen, and vex to our universe they set up on mars. Trying to make an outpost there to further it's path but as we see the vex impede them. [b]the darkness[/b] In the beginning there was nothing. Shit went down and your mom got banged by your dad and you're born and what not. The darkness was formed, a "dark mirror" to the traveler. Perfectly the same in all except it's one and only difference, darkness. Try a s it might it could not hide the light. The traveler was going to defeat it when it fled to the black garden. Safe it slept, and was discovered by precursors. They worshipped it and waited for it to grow strong again. In their waiting they changed, becoming vex. Some vex stayed to await it's final rising while others set out to pursue it's quest. You enter the garden forcing it to awaken early, weak and weary from it's fight with the traveler it forms gate keepers to try to stop you but with no luck. It runs again. It goes far away to a seemingly primitive planet, the inhabitants were feral beings with magic like science. They were the hive. Less intelligent than the vex and less superior they fell faster and harder into the darkness. The planet became uninhabitable so they fled. The darkness urged them towards the moon setting it's plan into motion. The darkness left. It goes to a civilized world of fallen. Respectable houses rule, keeping blood lines strong. The darkness set it and anarchy broke out. The lower beings started to rise against the noble houses. The houses weren't fighters, they were well educated and used others to fight for them. Quickly they set into work making sentrys and the devil walker. It wasn't good enough, they left to rule a less brutish world, urged by the darkness: earth. It was time, the darkness would destroy the planet that set forth a guardian to destroy it in the black garden. It had it's army and it was ready for everything, or so it thought. The traveler was on earth, aiding the humans. The darkness still arrogant that it could win with its army set forth to war. The humans weren't ready for the attack and the darkness was seemingly going to win, until the traveler shone brighter than ever before. The travelers light banished the darkness once again, but at a cost. It was weak, extremely weak and the army's of darkness were still about. The humans needed it, but it was already falling asleep. In it's last effort it created the ghosts. [b]the speaker[/b] An intelligent man, the speaker quickly rose up to speak for the traveler as it slept. It seemed almost too quickly that he stood up and claimed his position, but in the time of tragedy not many noticed. What could his plans be? An agent our darkness? Personal gain into power? Only time will tell. Let me know what you think, and if you want you can take any theories you want from this.
