"Ahh! my Lord, the plain is without doubt a planet and the pyramids some form of imperial power which threatens our Saviour, the great Khorne! I will consult the annals, my Lord"

....anon

"So my lord, see, here is the answer. The planet Ahkra'van was once a lucious fruit in the hands of Khorne. Our Redeemer thrived on the hedonistic souls who worshipped him above all else. The people built temples and elevated Khorne on a truely gigantic pedestal so as if he would hold the heavens aloft. It was truely a trophy of khornal power. But although protected by a mighty fortress his servants were negligent in their vigilence and the filth of the false prophet's inquisition came across the planet cleansing it of all life. It has remained untouched for several millenia but I have received news that now the heresy of the imperium has once again invaded the resting place of the almighty Khorne and set up a base there. Your vision my Lord is surely a demand from our Redeemer, that the planet be freed of imperial infestation and returned to it's rightful owner!
Our spies inform us that recently an imperial force invaded the planet. Although they report of only minor activity, it would be wise not to under-estimate the situation, my lord".
