"Each background also should include the following; one close friend, one unknown friend, one known enemy, one unknown enemy, and one contact within your faction should you choose one. Please include an appropriate amount of detail for each. If you are not selecting a faction, also include one contact in Absalom for your character if you do not originate from there."
I am relatively new to Pathfinder. I know absolutely nothing about Golarion or its NPCs. Where exactly am I supposed to get friends, enemies, and a Faction or Absalom contact before the campaign even begins?
