I'm incredibly worried about the Traveler considering Grimoire now suggests it was going to leave us before Rasputin stepped in. In the best-case scenario it's been worn down(as some of the dreams of alpha lupi cards suggest) to the point where it doesn't know how to do anything but run. In the worst case it could actually be a method used by whatever's behind the Darkness to find new places to conquer; the Fallen have always called it The Great Machine and that might not be impossible if it just happened to exude energy passively which we mistook for sentience. Of course, knowing the Traveler isn't some benevolent protector also raises questions about the Speaker's motives. Either he's delusional or there's something shady going on here. That we're having a revelation like this when it's only year 2 would lead me to believe the secret won't make it until the end of the franchise before being exposed; it'd be interesting to see how the Vanguard and others react knowing they've been giving lives for something that was about to abandon them.
