This is only a short review of one of the stories in the Lost Signals of the Terran Republic. A Fragment of Empire is a short story by Marc Miller. It was the story that I read first.
So, what is it? It is presented as a fragment of something larger. It is the story of the politics of nobles in the Spinward Marches and how the assassination of Emperor Strephon affected the Marches. It is a story about Norris and his loyal employees and how he became the Archduke of Deneb.
Canonheads will love this short story from Marc Miller himself.
Personally, I hope that we may get more fragments and eventually a new Traveller novel (called Empire) from Marc Miller.
