2.1.0 Scenes, Rounds, And Mission Time
During play, three special measures of time are used: scenes, rounds, and mission time.
2.1.1 Scenes
A scene is a time measurement used to determine how often certain abilities or actions can be taken. Some powers can be triggered only so many times per scene, while some special abilities only work once per scene.
A scene is one particular fight, event, activity, or effort that usually doesn’t take more than ten or fifteen minutes. A fight is a scene. A chase is a scene. A tense backroom negotiation is a scene. So long as the PCs are doing the same general activity in the same general location, it’s probably one scene. Most scenes don’t last more than fifteen minutes, though a GM can stretch this if it seems logical.
2.1.2 Rounds
Combat is made up of rounds, each one lasting approximately six seconds. A single combat may involve multiple rounds of action. A round begins with the actions of the side that wins initiative and ends after the actions of the side that lost initiative.
2.1.3 Turns
Sometimes it’s important to track the time of a more complex operation, like exploring a dungeon or navigating the trackless depths of some ancient ruin. In such cases, the turn is a common measure of time. Each turn lasts ten minutes and is equivalent to one scene for those situations when it matters.
