Turn

  The point during a round when you declare your character’s action is called your turn.
 

Round

  A unit of time used to measure combat scenes, considered long enough to take one action. A round normally lasts about three seconds in combat situations, but could potentially represent more time during fights involving large battle groups.
 

Scene

  Scene—A segment of action and roleplaying that takes place without a cut in time and location, like a scene in a film. A scene takes as few or as many rounds as are necessary to resolve events—in-setting, a scene might be as short as a few minutes or as long as a few hours.
 

Session

  Session—A single evening of gaming, generally encompassing several scenes.
 

Story

  Story—A discrete portion of narrative that often takes several sessions to play out. Stories generally have an overall goal or framework, such as “Overthrow the satrap,” “Find the ancient ruins of Lost Zarlath,” or “Escape from the Wyld Hunt after being ambushed and trapped in the city.”
 

Chronicle

  Chronicle—A complete game focusing on a continuous series of characters or events. Similar to the full run of a television series or cycle of books.
 

Downtime

  Existing outside of this scale of progression, there is also: Downtime—Time between scenes or sessions that pass without roleplaying, which is narrated in an abstract fashion—“Three weeks later, you finally arrive in Nexus,” or “My character spends the remaining days before the festival rigorously practicing martial arts on the mountaintop.”
