Please read some fluff b4 the next one :)
look, it was good and all but there were fluff problems all over the place
1:I know the devil thing was mentioned so im not going over that
2:No one in the 41st millenium talks that way they all sounded like some bad mouthed vietnam vets. not men who have had their religion hammered into them from before they could understand gothic. although normal people may be vulgar at times... words like "fuck" and "hell" would not have survived (around)50000 years (the date "40000 is based of the imperial calender which starts at the time the emperor began his "great crusade" not our calender which starts at the birth of christ) and on most planets have been replaced with local variants or dropped all together
3: spacemarines dont cost any money.. nothing does in the armies of the imperium, if troops are need somewhere, they are there. the armies arent funded by anything they just are... also even if the space wolves where paid it doesnt guarantee that they would show up spacemarines are a society apart from the rest of the empire, even inquisitors cant make a spacemarine chapter give up a few of it brothers if the chapter master doesnt want to because spacemarines are above inquisitors
4:space marines DO NOT talk like that, they wouldnt say something like "oh that was a nice speach, but i dont want to listen to you so now you have to die punk!" they would be more like "DIE BY MY HAND FOUL XENOS WORSHIPPERS!!!"
5:Spacemarines do not want tyranids of any sort to kneel by anyones feet... they would rather they were just dead or never there in the first place
6:in actual fact it would be more likely for the imperium to send in an assassin instead of a couple of scouts
on the plus side you did get some things that most people dont know right
1:your right cults would use las weapons and not have access to anything better (exsept stubguns and autoguns)
2: actually the imperium does manufacture helecopters and they are open for civilian use(un armed of course)... perfect way to sneak in a couple of scouts (if the cult thought it was some civilians come to join there cult they wouldnt shoot them down"
3:space wolf scouts are different than normal scouts, instead of in most space marine chapters where scouts are new recruits, space wolf scouts are veterans who have shown an aptitude for stealth, and are allowed to be a little cocky (if thats what you were going for)
nice job, liked most of it so yah just brush up on some things for the next one (i have no life thats why i know this stuff so dont feel bad if you didnt)
P.S. sorry about the long post i just had a lot to say.
