Causality

[16]

Causality refers to the force or forces that shape a particular fictional universe.  In other words, the causal setting of a narrative is comprised of the laws and logic that order its fictional events. 

There are four basic causalities: supernatural, in which the narrative's governing forces exist beyond its natural world; naturalistic, in which the events of the narrative are the result only of human behavior and other aspects of the natural world; chance, in which the narrative is driven by implausible occurrences; and metafictional, in which the author makes clear the fact that he or she is the true governing force of his or her fictional universe.
