Alright, I got like 8 requests to make a ACTUAL 40k rp, Lan said Tau vs IG but unless you guys like to write about trench foot.
So instead tis gonna be Imperium vs chaos, :D

Story: Deep within the galaxy, Lies the boarder world, Markos. Markos has been a Imperial planet for over 10,000 years, but it has always been in threat of chaos, for Markos lies on boarder between our galaxy and the warp.
At the end of 999.41m A massive warp storm engulfed Markos and brought the planets defense force to its knees, killing or converting the defenders and terrorizing the citizens. The chaos lord who brought the warp storm, Eliphas the Demented, was using Markos as a preparation ground, for his long planned campaign against the Imperium. But his campaign would be delayed, one imperial guard ship escaped the massive slaughter, and warned nearby planets of the oncoming darkness. The imperial guardsmen of Lorn V answered the plead for help, and brought with them the hammer of the emperor, along with the Imperial guardsmen, came the Space marines of the Ultramarine chapter, the Adeptus Arbites finest and most loyal.
This is beginning of a dark crusade, and only one side will prevail victorious.

Note: I'll be Eliphas the demented you imperial scum >:|
