I swear i remember reading somewhere that Rasputin murdered millions of humans for something in the grimoire cards. I'll try and find it again, but if i'm correct, i doubt he's a good guy. I am skeptical about the traveler and speaker though. There is also information floating around about Osiris. A warlock who was exiled for investigating the vex. I believe it was he who also killed himself frequently because upon death he would see flashes of his former life; memories blocked upon becoming a guardian. It makes me skeptical when the people investigating our enemies, and working to understand the past are labeled as traitors and exiled. Edit: the speaker also makes a comment along the lines of "those who hide in plain sight have their own agenda". Seeing as he is the only person, as yet revealed, who hides[behind a mask] in plain sight, i don't really trust him. He also seems to have knowledge of the nine; a group who seem extremely familiar and comfortable with darkness, even creating people out of darkness(Xür).

Maybe he's the good guy and the speaker wants him destroyed so he can resurrect the traveler and conquer the universe in order to make us all eat waffles for breakfast

Lol. Nice.
