What happens when you mix a group of Warhammer Bronies with working space marine suits and weapons... All while being in Equestria as their combat instincts begin to get more and more like the real marines their costumes are based off of...? Well... We get to see as they find themselves becoming holy zealots of bolt and flame who march without fear or question for royalty that would rather the guys with fully automatic grenade launchers stay in a place where they won't kill someone... or somepony.
The group is based loosely off of how a Warhammer 40K Deathwatch organization is set up, OC's are welcome in later chapters since they'll be the foundation of more important squads once the genetic manipulation of ponies becomes a thing... a thing? Yeah, we'll go with that.
-- Small note--
The current coverart is a placeholder until I can get something better to show what the Lunar Templars are like, it shows the current paint job of their armor, it's just not a good pose...
Note 2: Sex tag is for rated-T scenes, as I do not trust my own skill for clop.
