A Warhammer 40,000 story of life and romance in the grim darkness of the far future where there is only war. The Catachan 54th "Sky Reapers" have been deployed to the far off world of Zyrantiel, on the infamous "Thunderous Front", to ply their trade of anti-air expertise against the foul Ork. Along with them is a very minor detachment from Forge World Metalica, who have goals of their own. Techpriest Artisan Rileigh of Forge World Metalica comes to meet Sergeant Charr Stag of the Catachan 54th, and declares him her main liaison, leading to a lot more interaction than they might have otherwise had. This interaction between the wildly different cultures of the Adeptus Mechanicus and the Imperial Guard generates a fair amount of friction, but also sparks. Can this fragile love survive the horror, violence, and darkness of the 41st Millennium?
