Middle Earth

Lord of the Rings in many ways began the fantasy genre. Though not available for download, it's a requirement for any library.

Campbell summarizes these elements, which became known as the Hero's Journey, in these words:

A hero ventures forth from the world of common day into a region of supernatural wonder: fabulous forces are there encountered and a decisive victory is won: the hero comes back from this mysterious adventure with the power to bestow boons on his fellow man.

Campbell goes on to make an exhaustive list of all the possible steps in the Journey. But we don't need to write a game that contains every motif ever to appear in a mythical story. Instead we're going to focus on the most important elements – the ones that have to be there. These are:

Establishing the hero's world
The call to adventure
Entering the mythological woods
Trail of trials
Encountering the evil one
Gaining the hero's prize
Returning that prize to the community
