So I have a table top/nation role play hybrid that I want to start up, here is the storyline that introduces the conflict.

Story:
In the year 2234 A.D. a group of settlers traveled nearly 100 light years to reach a planet known as Kilniv III.

The planet appeared to have an abundance of valuable minerals and other raw resources. The land was seemingly fertile and the water was clean and drinkable.

After nearly ten years of development, the progress on Kelniv III ground to near stand still. The rich veins of ore that had been extracted suddenly ran dry, the rest were found deep within the mantle. Too deep for these people to reach with their current equipment.

It was discovered that many to the plants that were recent evolutions. They had little to know roots, leaving everything underneath the thin layer of nutrient rich topsoil rocky and barren, leaving any farmable land useless after a couple of years.

The the ground was more dust than dirt. As a result, the winds from any weather would kick up detriment, further tearing up farmland and soiling the water. The process for removing the minerals that were toxic to humans, but beneficial for the plants was arduous and time consuming.

The settlers soon sent a message out to the United Systems Government that they needed help. Of course, help was promised within a few years.

That help never came.

The colonist had lost hope of ever gaining help. So, starving and lacking the resources to continue the basic functions of society, the colonist of Kelniv III pushed what little resources they had left into building great ships stocking them with whatever they could scrounge up.

Then, they invaded the nearby colony of Gensai V.
