SilverFox seems to have a lot of clout/power compared to the other travelers. No one seems to undo SF’s edits, so I’m guessing there’s more than just a hierarchy of trust there, but that SF has some kind of actual power to incapacify other travellers.

I’m guessing it’s not a master reset switch (like the film Primer), since they have to physically go there and extricate the assailants physically. I’m guessing it’s some kind of physical power, or at least meticulous planning in grabbing the assailants before they commit the crime.

SilveFox makes it sound easy though, like herding children at best, so I’m thinking more along the lines of some kind of extra power/tech to teleport too(?) which would facilitate the placement of certain items (goats, olive oil, etc.) and give them a huge upperhand in grabbing travellers who probably have to do some degree of walking.

Or maybe SF’s device can travel multiple times, whereas other users have to use it more sparingly, limiting the damage they can do

I have had a story idea of a similar time travel concept (with a fake evil person) where each chapter is basically “Ok, thenworld is ending, but we will time travel and stop this despot.”. Then they send say, a woman back. Next chapter, "Ghe world is ending, we shall send someone back to stop this despot and his wife, "him, his wife, and his manservant, “hum, his wife, and his respected general, and his manservant.”

You get the idea. Basically, everytime travel goes back and gets seduced into helping the evil guy, and each new timeline is unaware of previous attempts, but the historical records mentions “new people”.
