Okay so I've been talking to a few people the last few days trying to piece together a few characters, and work out what this huge secret that DeeJ posted about in the Vault of Glass. When you first talk to the stranger, she talks to her team them teleports to God knows where. My theory is that she may have something to do with the house of wolves. Every Raid there is a character that survives, just one. Vault of Glass there is Kabr, the legend, the myth, but I'll come back to him. Crota's End there's Eris, so what's to say she's not the survivor for the house of wolves raid. There's no proff that I'm right just a hunch. Now Kabr, he went into the BIG with a 6 man team, 5 were erased from time by the Gorgons, and he survived, only to go back and vanish. Now nothing is known about anything after he returns, what if he didn't die, that he went in and the Nine recruited and rebuilt him because he was so badly injured that he could not be recognized, maybe Kabr is Xur!! There is minimal info on the Nine, but maybe Kabr is Xur. Just a theory, I have no proff just a hunch, discuss if you think there's any chance.
