Assuming you use a GMing screen at all (or perhaps more than one), what do you keep behind it?

My typical GM’s-side loadout looks something like this:

  • Adventure
  • Blank pad of paper for taking notes
  • Carefully-selected pile of dice (not so many as to be messy, not so few that I need to dig out more mid-game)
  • Pen
  • Counters I expect to need
  • Little notes stuck to the inside of the screen
  • Copies of stats I reference often (recurring NPCs, etc.)

What do you have behind your screen, either for your own convenience or to hide it from your players?
