Disclaimer: This is a fanfiction of Star Trek which I (henceforth named –AD) have created because I have never written anything technically considered a fanfiction. I do not own the rights to Star Trek, as such all potential proceeds received due to this work will not go to me blah blah blah.
In this work the main character, Edward Alighieri, is a member of the Q-Continuum who serves aboard the U.S.S. London as the Chief Military Officer (CMO). In most cases, ships in the Federation do not require any military expertise beyond that of the Captain and First Mate, but after the Battle for Deep Space 9 some reform was necessary. Some of the leaders of Star Fleet saw how much the cost of hiring a new officer on every ship would be and recoiled. However, one cadet straight out of school wrote in his thesis how only one really good CMO would have almost the same effect as one per ship. Cadet Alighieri wrote in his thesis that, after the invention of subspace communication, one CMO would be able to advise every ship in a time of war.
Now you might be asking yourself, why would a member of the Q-Continuum go through the trouble of getting assigned to a Federation starship? The answer is quite simple really, he was really bored. So bored, in fact, that he'd be willing to kill in order to protect his identity as one of the god-like Q.
