Trev maybe the fallen e.g is a race that was blessed with the resources that the traveler gave to them cuz' they have a really advanced technology and the traveler used them for it's own selfish need and thats why they became scavengers and i also read that in one of the rasputins grimoire cards it was explained that rasputin attacked the traveler so it could'nt escape and abonden humans. But my point is that there may not be a "bad" guy here a thing who wants to preserve itself and uses lesser creatures for its own goals :)

Dude whst they are trying to tell you is that The Traveler made the ghosts. We are hearing one side of the story. Your blind if you just take one side and go. And btw bungie is known for secrets in games so I am going to believe thst there is more to the story than " they are bad, you shoot bad. The end"

I don't believe he is lying as much as he is just re-quoting the lies we are all told. I think the ghosts are dupes like the rest of us.
