World Building: The Desolation of Wij

A quick World Building exercise by rolling up the geography across a polyhedral map.

The Desolation of Wij
Four thousand square miles of harsh, arid land. Wij was in the past devastated. The living cling to the city state on the coast and eastern semi arid/marsh farmlands that produce rice. What tiny communities exist inland across the desolation are mining operations and oasis. There is the occasional ruined ancient fortress, but noone who ventures near such places returns.

Starting a Game
Located far from the coastal city is Iron-town, a tiny mining community,

Iron-Town
An asteroid crater several thousand feet across sits out in the desert. It is home to a few families involved in mining iron ore that is crushed to powder and separated out with a mill-wheel made of lodestone. The homes are located at the bottom of the crater and the mill up over the ridge atop a trail.

The four families
The four families are Raly, Funber-Trint, Trint, and Windle. They have been mining in the Crater for a few decades:

• The Funber-Trints are Magicusers and elves keeping that magic craft in the family. The elf Jayn Funber married her apprentice Kopin Trint causing a bit of a rift with the rest of the Trint clan. 
• The Trints are religious, god-fearing folk who are not all that happy with their magic wielding cousins.
• The Raly clan built the mill and have helped expand the mine workings benefiting the other three mining families.
• Windle are more farmers than miners but they put their time in down the mines because there is money in it.

The mines
The mines are in a network of tunnels excavated from caves and fissures created by the asteroid hit lifting the surrounding rock.

Starting Adventure: the mine collapse
The PCs are putting in some time in the caves when a tremor shakes the mine and the entrance collapses. The pcs are trspped below ground with starting equipment and the only way out is to find an alternate route out through some unmapped fissure...
