The Imperial Stars

It's the 25th Century, and humanity has colonized a great deal of the galaxy, including several worlds apparently inhospitable to homo sapiens. The form of government selected to unite scattered humanity is an old-fashioned Empire, with hereditary monarchs, powerful aristocracy, but, happily, no serfs. A massive military and Secret Service is needed to keep this far-flung empire together. And you will be surprised at the hidden headquarters of the organization of spies and agents known as SOTE (Service of the Empire).
