So in the Witch Queen campaign, it's revealed that Savathun's plan is to bring the Traveler into her Throne World to seal it off from the Witness's reach. But she must have known we would fight her on that, and we know she knew there was a possibility she would lose and die (hence the contingencies she put in place to have Immaru bargain with us to bring her back). So why didn't she instead just move the Veil into her Throne World? The Witness needed both to exact its Final Shape, and the Guardians had no clue about or vested interest in the Veil at that time, she could have moved it into her Throne World without us even knowing (much less resisting). So why didn't she take that route? This is just something I was thinking about as I was pondering what will happen in the expansion and hoping the Final Shape sheds some more light on the Collapse, and in particular Savathun's decision to betray the Witness, kill Nezarac, and hide the Veil on Neptune. I realize the practical answer may be that the Veil was a later-developed macguffin, but I was just wondering if there was any more to the answer.
