Best For

Groups who want to collaboratively create vast histories spanning centuries or millennia: perfect for worldbuilding sessions, one-shots, or as a campaign-creation tool for other RPGs.

Core Mechanic

No dice, no GM. Players take turns adding Periods (eras), Events, and Scenes to a shared timeline. A rotating Lens player picks a thematic Focus each round. A Palette of Yes/No elements sets boundaries. Scenes are role-played to answer a specific question about the history. Play jumps freely across time.
