Yeah, that does make a lot more sense! thanks 
With reference to the original 6000 years question, there is a blurby background box on page 4 of Da Uvver book stating that the Imperium named the world and sent ships to explore and investigate it "hundreds of years ago". Assuming this is referring to the Eternal Vigilance and Angelis Base station reports, this suggests that at the time of Gorkamorka being set is still in M35/36.
A zogging long time ago from the 'current' 40k timeline.
EDIT: So the night stalkers are Necrons most likely? What other theories are out there?
