Demons are supposed to be faceless.

They seem to me to gain a face, though, when written down on a sorceror's relationship list.

What do you write there?  Just, "Demon 4d6"?

I think this is another dial.

When I was a player, we had our supernatural dial turned up pretty high by the end of our run, but our demons were still pretty faceless.

The one game I ran, the sorceress had a name of sorts for the demon she had a relationship with, even though she was insane and thought it was the ghost of her dead son, rather than a demon. Everyone in her following referred to the demon as the Lost Son.

The one sorcerer game that was posted in AP, where the Dogs ended up turning on each other because that one Dog wouldn't fairly judge the young man for being sexually deviant had a demon with a face and a name.

On the flip side, where the dial may be somewhat lower.. Who's to say that the demon couldn't have a name.. Such as Wrath? Gluttony? Lust, anyone? (yes, I know you can have a relationship with a sin.. This is a new twist on that)

I think it depends on the character.

You could have a relationship with demons in the following ways.
The demons
A demon
The Wicker Man
The Lost Son
The Demon of Pride
A Hate Demon

or anything like that.  Furthermore, the relationship could mean different things.  There was a wickerman in your hometown that you ran away and told the dogs.  They trained you and you came back and judged the dogs.  Or you particularly hunt down signs of Demons spreading pride.  Or are vulnerable to the promptings of a demon of hate.  Or you could hate the demons in general or shelter a demon in particular.

It is all up in the air.

Yes, I know it can be done many ways.

I'm asking about how you have done it in the past.

The relationship on one of my sorcerors is "My demon is indignation."

It leaves ambiguous whether the demon is a personal being, or merely a metaphor for the person's relationship with his own indignation.

I (and my group) are just starting a Dogs game.  The first thing one of my players put down, after his stats, was a relationship with "Varaethian, the demon that possessed my mother 1d4."  My first reaction was "oh, I don't think demons really have individual names--" and then I was like "that's a big fat Flag!  Go with it!"

I'll post AP eventually about how it affects the game.  (Our supernatural dial is high, obviously.)

This is gonna sound a bit strange, but my players made this call, and it's growing on me.

Relationships with sins include relations with faceless demons of that type - but don't allow sorcery.  Sorcery requires both a relationship with a sin, and a relationship with Hell (as an organization).

So, that's yet another way to do it.
