I believe this too and here's a grimoire excerpt that helps support it and here's the link to my own similar theory: http://www.bungie.net/en/Forum/Post/78923653/0/0/1 The Ghost said to me: You are a dead thing made by a dead power in the shape of the dead. All you will ever do is kill. You do not belong here. This is a place of life. The Traveler is life, I said. You are a creature of Darkness. You seek to deceive me. But I looked behind me, down the long slope where the blossoms tumbled in the warm wind and the great trees wept sap like blood or wine, and I felt doubt. When my Ghost raised me from the sea there was a thorn-cut in my left hand and it has not healed since.
