Think it's time for some left field thinking. Anyone else think that the premise of the game could be a lie constructed by the speaker... The game starts with the ghost reanimating you from bones, so in fact you were a dead human, now infused with 'light' from the traveller. We're told that the traveller terraformed all of the planets in our system and tripled lifespans - a 'golden age' , and then the darkness came and along - with that the hive and the fallen. Well how about an alternative theory, along the same lines as the film 'Oblivion'. [spoiler] Maybe when the ghost reanimated us he changed our perception so we see humans as aliens and fellow aliens (us) as human; essentially flipped our perspective. The traveller did in fact terraform all of the planets in our system but only so our system could be conquered, and it was. We are now fighting on behalf of the traveller to kill the remaining humans. And the darkness is just a way the traveller keeps a reign on us to ensure we don't see too much. We are the bad guys, and the humans (who look like aliens to us) are the good guys. Feel free to discuss, for fun of course ;-) [/spoiler]
