So yesterday I was leveling up my 3rd character running through the story mode and I noticed something interesting from a cut scene. Its the cut scene where you deliver the gatelord head, her brother states that it is dead. Shortly after the queen says "Gift in in sympathy for THEIR traveler. THEIR TRAVELER. She also always sounds so condescending almost like she already knows our fate. This means one of two things, she either is from another dimension with another traveler that has already been killed or there are multiple travelers(but this is highly unlikely since then other travelers would have come to aid this traveler) Anyways just thought it was pretty interesting that she was able at one point to travel through the dimensions. (SIDE NOTE) Personally i think the traveler is from the very distant future where humanity and technology progressed beyond belief and the humans are in battle with the vex and the vex plan on going back in time and killing humans before they can even go to war with them, well the humans find out about this plan and create the traveler send him back in time to lay dormant in mars to serve as a protector. *this is just how id like to see the story unfold.
