Varvara might looks sweet, but she's... actually an ageless demon, with powers that are the definition of godmodey. She can basically pluck facts out of the air about people and events, intuit things about them and know things that are going on that she has no reason or rational way of knowing. She can also appear to one single person in a room with no one else present seeing her. None of this is mind reading or manipulation - in the classical sense, she cannot read minds and has no psychic influence; she will never know what your character is thinking at any given moment, though the knowledge she gets herself will certainly let her guess.
There are exceptions to this! Supernatural beings will have more resistance to her, and priests/exorcists (the denomination does not matter) will be downright immune to much of her bullshit. They will be able to see her even she doesn't want them to and they will be much, much more difficult to generally get a handle on for her.
I will never do any of these things without a player's express permission and full knowledge of what Varvara will know and what she'll do with that knowledge. So, one catch all permissions post, let's go!
*Note: Anything she knows about your character can and will be used against them - likely nothing horrendous, but she is a troll. E.g. she may simply bring it up completely casually to freak them out.
Yeah, I know, it's long. I apologise. ;;
