My model: Propp

Vladimir Yakovlevich Propp is a household name in the field of narratology. As given by Wikipedia:

Vladimir Propp was born on April 17, 1895 in St. Petersburg to a German family. He attended St. Petersburg University (1913–1918) majoring in Russian and German philology. Upon graduation he taught Russian andGerman at a secondary school and then became a college teacher of German.
His Morphology of the Folktale was published in Russian in 1928. Although it represented a breakthrough in both folkloristics and morphology and influenced Claude Lévi-Strauss and Roland Barthes, it was generally unnoticed in the West until it was translated in 1958. His character types are used in media education and can be applied to almost any story, be it in literature, theatre, film, television series, games, etc.
In 1932, Propp became a member of Leningrad University (formerly St. Petersburg University) faculty. After 1938, he chaired the Department of Folklore until it became part of the Department of Russian Literature. Propp remained a faculty member until his death in 1970. (source)

In fact, the narrative functions of fairy tales as given by Propp has been used by many "propp-generators", that build a random tale by selecting some or all of the functions. One example is the proppian fairy tale generator once hosted at Brown and now available at archive.org, here.

The generator is a simple JavaScript that randomly selects one of the alternatives for each function requested by the user. While simple, it works very well thanks to the basic text snippeds written by Laura Tan and Celeste Lim -- most of the resulting tales have enough cohesion. I decided to start by adapting their texts as models.

And so, without further ado, here are the results for the first sentence (from the "absentation" function):

It is said in the mountain where I live that the ground is made of our flesh and blood. Old Parents who toiled, sweat, cried, and screamed all bled into the soil and made us who we are today.

It is said in the place where we live that our dust is made of our flesh and blood. Flesh And Blood who toiled, sweat, cried, and screamed all bled into the earth and made us who we are today.

It is said in the hills where I live that our earth is made of our relatives. Old Relatives who toiled, sweat, cried, and screamed all bled into the earth and made us who we are today.

The grammar is still Spartan (in fact, it is pretty much a list of synonyms), but the system is working. I tested the basic features of the language, and even caught a bug (shouldn't have confused Python's .title() with a proper capitalization of the first letter...).
