Well what do the rest of you have in store for the Ork-held worlds called collectively "'undred 'undred Teef"?
The first thoughts that comes to mind for me would be a truly epic campaign, when the Orks have reached their "critical mass" and an appropriate spacehulk materialize near those systems for the mekboyz to pull in and use to launch a full scale "waaagh!" against he nearby Calixis Sector.
The natural response from Battlefleet Calixis would be to seek complete subjugation of the Koronus Expanse and establish the necessary beach heads for the fleet to operate at maximum efficiency. This would of course mean that the prospering business to be found in the expanse which many Rogue Traders enjoy would be threatend due to the impending war and the inevitable expansion of Imperial control.
But! Perhaps the intrepid explorers of the expanse could manage to unite a sufficient force of independent Rogue Traders and notorious void pirates into a fleet capable of exterminating the greenskin threat and keeping the Koronus Expanse free for yet another couple of centuries? Will the Rogue Traders and Pirates be able to cooperate against a common enemy or will the alliance fall apart due to internal backstabbings? Just how far will the traders and pirates of the expanse go to keep battlefleet Calixis from pushing into the expanse and subjugating it under the iron shod heel of the Imperium, effectively putting a dead end to free trade in the expanse? Will the impending waaagh! originating from 'undred 'undred Teef simply wash over and destroy everything in it's path or can the greenskins actually be stopped dead in their tracks?
Only time will tell.
But tell me, does it sound epic enough so far?
Also, what sort of diabolical and epic plans are you cooking up that includes the Orks for your Rogue Trader campaign?
