All actions take place in rounds.
Each character's speed and movement help determine how many action points they are granted each round in order to perform actions and move around. Each moevement and each action reduce the number of action points a given character has remaining for that round. Stamina is regained each round, but often much more slowly than action points. If a character has no remaining stamina, they cannot perform actions that require that kind of stamina. Events may cause further events.
