I haven't seen the scene as I haven't accessed the Dream City yet, but there are a ton of rumours out there that the original Destiny storyline was nothing like the one we got now. Supposedly the Traveller was the bad guy/object in Destiny reviving Guardians to get rid of the other species so the Traveller can ultimately control the universe; similar to what I consider Unicron is like in Transformers. Staten was the lead writer in it, but after Activision scrapped and redid the mumbo jumbo mess we get in the original Destiny, Staten left the company. My bro is big into this stuff concerning video game companies and said that when you bought the collectors edition in Destiny 1, they sent you the original grimoire cards that had the original premise on it. Interesting to say the least...
Yep, Ive heard similar rumors, though the ones I heard suggested that the traveller was an entity that fed on conflict. It would travel from system to system and sow conflict by giving races tastes of power, enough to become obsessed with it, have them battle out, then leave, leaving the broken, obsessed corrupted remains of the peoples it encountered to chase it around as minions of the Darkness, with nothing but mad hatred for the travrllers new chosen.
By that understanding, the end of the Destiny 2 campaign is much more interesting. The traveller didnt choose you over ghaul because you were righteous, it chose you because it deemed you a more efficient killer.
Forsaken did actually, finally start asking explicit questions about just how good and righteous the Guardians are. And pointed out repeatedly, this giant ball in the sky has basically amassed a large, very well armed, zombie army.
