A Roleplay about Warhammer set in Equestria

Well hi there I am Elusive and i have decided to do an RP about Warhammer 40000 but set in Equestria.
Setting - Equestria is a war torn nation, the Imperial Guard can barely keep a hold and with various alien threats attacking the Canterlot stronghold it falls on a team of Space Marines, Inquisitors and hired mercenaries to defend this peaceful land, or die trying...
Well then there are a large choice of races for you to choose from, if you wish to be part of the Imperium you may be either;
Imperial Guardsman: Backbone of the Imperial Armies, strong, dependable and pretty damn smart too, however they are still only human
Space Marine: Vanguards of justice and strength, 8-10ft tall warriors capable of fighting the toughest foes and usually entire squadrons on their own with no assistance
Sister of Battle: Female warriors who are trained at birth to battle and have an almost fanatical devotion to the Emperor, almost as strong and tough as a space marine
Inquisitor: Highly trained Imperial Guardsmen trained to flush out Daemons, Traitors and Xenos races and remove them
However if you wish to be a hired thug defending the planet you may be;
Ork: Ugly, Brutish and rather smelly, these words are used to define an Ork best, speaking mostly in grunts with pitiful grammer they usually let the actions speak for them instead of words
Eldar: Ancient warriors who have watched the Galaxy for many eons and have guarded it with their lives, fast and nimble these warriors can easily catch their foes out
Tau: Highly advanced warriors who can traverse the toughest terrain and even breathe in water, as can a space marine but these are much more nimble and have access to the most advance weapons known
If you wish to RP as a agent of Chaos we even have those;
Traitor Guardsman: An Imperial Guardsman who has fallen to Chaos, equally as powerful as a normal guardsman but depending on the god they follow they can be bestowed with some... Interesting gifts
Chaos Marine: The only thing that almost bests a Space Marine in every aspect, one that has fallen to Chaos as now it has a gift which can grant it much more power, they have access to the Chaos Forge which has very powerful weaponry... As well as other things...

The rules are rules you would expect from any other RP and well the content can be described as... Mature as there will be much killing and maybe some lovemaking, other races may be added and other things too... Hope you join and have fun for this was an idea i had recently

Ponies do not exist as this is a what if story where Equestria is just another planet in the war to control the galaxy... However Luna and Celestia exist... As do many other characters...

DISCLAIMER: We need a picture if we get popularish... Artists i beg you to assist me...
