<Snipped quote by KabenSaal>

Travelers (and workers) are already pretty much spirits possessing mechanical bodies.  Anyone trying to possess one would have to directly conflict with those spirits.  For a being accustomed to possessing humans, this would be difficult, because Providence and Salvation leave a very strange sort of magical signature that is difficult for other beings to acclimate to.  Travelers in particular are difficult to possess, because to become Travelers in the first place they require fairly strong spirits.

So, instead of sending Blanks to possess them, Emily needs to go on site and subjugate the spirits already present?
