Porkins’s life will be a lonely one. He will work. He will paint his Warhammer miniatures. He will chat about fandom with his few weird friends. And in time, he will die more or less unmourned.
Then everything changes. The world falls apart. Actually, all the worlds fall apart. Suddenly the Empire is at war. There is a Rebellion. And Porkins meets his moment.
Porkins could never make it in a real military. But the Rebel Alliance is not a real military. The Rebel Alliance is a scrap-heap outfit that needs anything and anyone it can get. It needs awkward fat autodidacts who have spent their entire adult lives as involuntary celibates, poring over the proper employment of the Incom fighter series in exactly the sort of engagements the Alliance now encounters on world after world.
