Cornucopia, a border world cut off from others by distance and isolation

Homeworld of the Varuke dynasty, having been founded by Hades dan Varuke some several thousand standard years past. A temperate world with a large and verdant capital province, August Respite, growing cash crop plantations and offering stable wealth to the elite.
The other provinces however, are far from homely; bayous, jungles, sand dunes, canyons, and more housing behemoths or ptera beasts that could only be dealt with on equal footing by the awesome power a of knight. The common people of these places are just as rugged, adaptable, and territorial against invaders as an Alpha Grox. The Knights of House Varuke maintained a firm hold on the capital province with a policy expanding only in eras of firm political control making use of ancient fragmentary STCs to build Questoris and Armigier Knights to help combat the large beasts of the world and expand over the centuries.

When a large asteroid had entered the system it wound up lodged in Cornucopia's orbit, the nobles were rejoiced as it could mean mineral wealth that was easier to acquire then the veins located deep in Behemoth territory. Then disaster struck, a fragment of the large asteroid seperated from the whole and crashed in the desert in a storm of radioactive green glass, but, it was not the only green thing to grace our world that day...

Orks had invaded and been deposited on Cornucopia! The asteroid was in fact a rok that had veered off course and lost the means to correct its trajectory. What minerals it had were being formed into ork war-machines which would ravage our world. Feral orks would fester in the bayous and jungles for countless years of warfare kept in check only by our knights and the angry gargantuan wildlife.
House Varuke struggled to maintain order with their ancient knights and vestigial navy. It was in their darkest hour of need that an Ark Mechanicus ship arrived searching for ancient knight patterns rumored to dwell on our isolated world. House Varuke made a pact with these Martian Tech Priests that in exchange for our knowledge and alliance we would gain power that could destroy our enemies.
The Mechanicus brought with them new more efficient designs and powerful weaponry; strong enough that using them allowed us to cleanse the ork infested asteroid, and the behemoth territories, giving us access to considerable mineral wealth that the Mechanicus was ever eager to trade for.

The current head, Daveet dan Varuke, had been sent to Mars for his education to learn veneration of the Omnissiah, arcane knowledge of the machine, and mastery over the Throne Mechanicum. He had spent most of his days training body and mind to endure augmentations improving his power as an individual princep and pilot of a knight house, or perhaps one day with sufficient faith in the machine, and sagacious veneration of steel, a Titan. Shortly after finishing his education he received a call to arms to muster his knights and protect a world named Koronam.
