The Event Story The whole point of the story is about the restoration of the proper order of the universe.
Departure - Heroic figure hears the call to adventure (and sometimes refuses call): he is called to restore order to the universe; he receives aid from a wizard, an elder, or supernatural force (usually in form of a magical weapon), and undergoes first trial by fire.
Initiation - Hero undergoes more trials; he falls for a goddess and is tempted by a temptress; he meets his dark father and is wounded; he finds great riches.
Return - Hero restores order by defeating evil king & returns home, older & wiser, to empower others.
Notes:
In the Event story, something is wrong in the fabric of the universe; the world is out of order. In the ancient tradition of the Romance (as opposed to the modern publishing category), this can include the appearance of a monster (as in Beowulf), the unnatural murder of a king by his brother (as in Hamlet), or the reappearance of a powerful ancient adversary who was thought to be dead (as in Lord of the Rings). In all cases, the "golden age" has been disrupted, and the world is in a state of flux.
The Event story ends at the point where a new order is established, or the old order is restored. The story begins, not at the point where the world becomes disordered, but rather where the chracter whose actions are most crucial to establishing the new order becomes involved in the struggle.
Most of you probably recognize, in this structure, the story of Luke Skywalker from "Star Wars." "Star Wars" doesn't begin with the fall of the Republic; it begins much later, when R2D2 first appears to Luke and involves him in the struggle to destroy the Empire and restore the Old Republic. J.R.R. Tolkien's Lord of the Rings trilogy begins when Frodo discovers that the ring Bilbo gave him is the key to the overthrow of the evil Sauron, and ends with the destruction of Sauron and the complete reestablishment of a new order. This is Joseph Campbell's monomyth--the common story that most myths and legends and fairy tales follow.
