So in Caydes Secret stash mission at the end, ur ghost tells you (if u examine a certain spot) that a secret Gaurdian sleeps and that ur ghost tried to wake him. So at first and most popular thoughts were that it was a reference to Master Chief. Bungie, u got Destiny now, move passed. Any way, back on topic. I think that this has to do with the actual destiny story or lore. I mean it's kinda a big deal. A powerful Gaurdian that ur ghost wanted to wake but couldn't? What if he's evil now or will he ever be awakened? What do u think?
I understand your wanting for Bungie to move on from Halo, I myself was never into Halo I was a Cod fanatic but i did enjoy the multiplayer for Halo. I do think bringing Master Chief if not into a large role but at least make him relevant in the Destiny universe it would absolutely bring in what ever halo players that aren't playing Destiny yet. If not, it would be baller for Bungie to give us a little more about before your guardian is awakened. Like stuff from the Golden Age or when the darkness first started tracking the traveler to earth. Just a thought what do you think?
