That the big mini planet thay you can see in the tower is actually the traveler, crazy stuff isn't it? I m for real by the way... never pay a lot attention to that thing, you know in a sy-fy Universe i would expect some satellite floating around here and there, also i was way more busy grinding than being worry about that sort of trivial stuff. Idk but in the spanish version everyone says things like "-oh the long gone traveler, when we will see it again?" Eris morn also say that its dead so i imagine it being the corpse of a god floating in the space and guardians and ghost as the remaining pieces of him. I have been playing destiny for 7 months by the way.
