Not going to lie if I was a demon I would just mess with black runners and ashlanders without trying to inform them. I would get just close enough so that they know that I see them and just keep following them like how ancient human hunters would keep following prey until it got too tired to keep going. If they got too tired and tried to sleep, I wouldn’t close the distance I would just dip in and out of their peripheral to make their rest as distressing as possible. I would also try to keep them in the black zone as much as possible and even if I did let them out I’d make sure they knew I let them get out. With this in mind how long do you think Loken could deal with this before he starts to lose his mind?
