Fictionary: Building your own Westeros/Middle Earth

Looking to cash in on the whole game of thrones thing? Need to create your own Lord of the Rings film franchise? Lets start with mapping the world. This can be easy and random. The basic world globe can be laid out on twenty triangles. Unless you have an idea as to what the world looks like you can decide what the chances of geology occuring are:

So you roll once for each triangle and build a world map.

Thats big picture. Up next you focus on the local area your work is in. Middle Earth, Westeros are small regions in a large world.

Having come up with an idea of the local setting we have a map with a bunch of places on it. So lets give these places economic value. The reason the political situation exists is because of the haves and have nots.

So roll 1d100 for each geographic region over and over until you get a no Mine result and then move on to the next area. Count multiple results. The number constitutes 0-none, 1-little, 2-some, 3-considerable wealth.

Piecing it together
It all means the mountains of doom and those who dwell there had considerable copper and tin which feed the bronze age. To a lesser degree those in Weselwood also had copper and tin so they also have bronze age potential. This provides for conflict between the mountain folk and the Weselwood folk. The Kron hills are ripe for plunder without bronze.
 The southlanders and the folk of the Greatwood can trade tin and copper to achieve a bronze age, and given southlanders have access to sea salt, a primitive currency to buy tin. So here we have bronze age alliances, and foes. The southlanders, mountain folk, greatwoods and Kron hills have gold and the Weselwood dont so there is wealth disparity across the river po. The Weselwood folk can harvest sea salt so they have a currency.
The Kron hill folk, without even bronze technology will likely be butchered in the middle as greater foes battle over the Kron hills. Peoples of the Kron hills are taken as slaves by the mountain folk and others become refugees. The Kron hills might become borderlands.
 By the iron age we find only the southlanders and the mountain folk have iron and coal. The old treaty between the southlanders and the folk of greatwood is at an end. Thus the rivalry of the bronze age carries into iron age conflict. Weselwood have iron but no coal so they might finally be dominated by the southlanders or mountainfolk.
There isnt any salt deposits or silver so currency is salt from the ocean. This means the southlanders have dominated in trade and the mountain folk raid for salt. There is a long history of raids by mountain folk. Now they dominate in conflicts with iron weapons.
The Iron Age ends with Book One: The Doomed Crown. It is a tale of a massive invasion as Tark the mountain king invades to occupy the Southlands and take it all as his great kingdom. Outflanking the southlanders His war Rafts come down the river Po. Many wealthy southlanders flee south across the Sea in primitive fishing boats with most of their wealth, soldiers and supporters, betraying those who stayed to fight...
As this is a tale told from various character perspectives add a list of character experiences:

Tark: After a battle for his position in which he gains a gold torc crown and declares himself king of the mountain folk. He somehow has a dream through the eyes of his messenger that the southlanders reject his demand to surrender. offended by the refusal of the southlanders to concede to his rule Tark sends half his army through the greatwood. The other he sends down the river Po on War Rafts- himself included. On the way south he sees a witch of the greatwood through the mist on the banks of the river po bow to him. Emboldened by this omen, Tark claims the Southlands.

Haas: A southlander scout discovers a Barrow in the Kron hills while being hunted by mountain folk falling in through a chimney in the rock. He finds a gold torq crown of the ancient Kron people and a great stone ax engraved with the pictures of the Kron. The crown is taken from him and he is enslaved. He is sent to southland with a message from 'king Tark' to demand the southlanders surrender. He initially does not but a witch curses him at the Barrow forcing him to obey Tark who thanks to her magic can now see from Haas's eyes. The southlanders imprison Haas as a madman. He escapes during Tark's attack and flees by boat across the Sea.

Rulk: A mountainfolk warrior who comes into posession of the gold torc crown of the Kron. He fights Tark for control of the mountain folk but is gravely wounded and thrown from the falls where the river Po begins. A witch of the greatwood pulls him from the water alive. She uses him for sex before killing and cooking him.

Mawi: A witch of the greatwood forsees the discovery of the torc crown of the Kron, she pulls 'the lesser evil' from the river po and having used Rulk's broken body for sex, kills and cooks him. Her child will one day challenge Tark. She journies to the Barrow to retrieve the ax and has a run in with Haas. She curses Haas forcing him to deliver Tark's message and she carries off the stone ax. During the invasion mountain folk passing through her area attack her but she curses them. She bows to King Tark as his war raft heads down river.

So there you have the beginnings of a setting and the layout for a story. There is also a set up for the death of Tark by stone ax at the hands of Mawi's son 'Maw' whose rise to manhood will be in Book Two: The Witch's Maw.
