If you are busy setting up a campaign area, such as a city, you'll have a bunch of characters, some major and some minor.
If you want to go a step further, particularly if urban intrigue and faction struggle is going to be a focus of your game, you can use these charts to generate how they relate to each other.
1: Violent hatred
4: Severe dislike
5: Mild dislike
9: Business like
Depending on the character's relations in the campaign, this may suggest some interesting setups. What if the two most powerful characters in a faction loathe each other?
What if there's a friendship between characters that should be enemies?
Have fun with the outcomes and see where it takes you.
If you wish, once you have established one characters relationship to another, you can roll 1D6 to see if the other character reciprocates:
1-2: 1D3 steps worse
5-6: 1D3 steps better
