The rules set forth here assume that you've read the Microscope RPG.

Scale of Time

The scale of time in an Epilogue game is much smaller than the typical game of Microscope, assuming months, years, and maybe decades.

1. Bookend History

Choose your starting and ending points for the narrative. Your epilogue will be divided into periods. Each Period is a large chunk of time measured in years or even decades.

Each period should have an evocative description and a Tone—light or dark.

2. Palette

A Yes or No list for the game

Next, take a step back and create the Palette for your game. This is a list of things the players agree to reserve the right to include or prohibit. This will be an aid to ensure that everyone is in agreement about what belongs (and doesn't belong) in the epilogue.

Since Epilogue is played after the conclusion of a campaign, the items in the palette will usually be focused on things that the characters can or can not do after the campaign. (This is different from a standard Microscope game, where the palette is more far-reaching.)

No surprise changes to characters
Yes armed conflicts continues with Condrol
No giant battles with Condrol, only small ones
Yes characters can die
Yes traveling to other parts of the world
No traveling to places not visited in the campaign

NOTE: Creating this palette can be challenging since the scope is small. If the players only come up with a couple, that is fine!

3. The First Round is What Happens in the World

For the first round the group should create things that happen in the world and not to the player's characters. This will give things for the characters to react to.
