With nothing left to lose, the Romulan Star Empire engages in all-out war against humanity, determined once and for all to stop the human menace from spreading across the galaxy. At the start of the twenty-first century, unconditional war swept across the Earth. A war that engulfed the great and the small, the rich and the poor, giving no quarter. Each side strove for unconditional victory, and as battle built upon battle, the living began to envy the dead. Chastised by the cataclysm that they had unleashed, the governments of Earth came together. Humanity vowed to put an end to war and to strive for the betterment of every living creature. A united Earth created Starfleet, an interstellar agency whose mission was to explore the cosmos, to come in peace for all mankind. It was a naïve wish that was battered by interstellar realities, yet man persists in the belief that peace is the way. Banding together with other powers to form a Coalition of Planets, humanity hopes that the strength each can offer the other will allow for peaceful exploration. However, the rise of the Coalition strikes dread within the Romulan Star Empire. They feel its growing reach will cut them off from what is rightfully theirs. The Romulans know that the alliance is fragile, that the correct strategy could turn allies into foes. Perfecting a way of remotely controlling Coalition ships and using them as weapons against one another, the Romulans hope to drive a wedge of suspicion and mistrust between these new allies. One Starfleet captain uncovers this insidious plot: Jonathan Archer of the Enterprise. Determined not to lose what they have gained, outmanned and outgunned, the captains of Starfleet stand tall, vowing to defend every inch of Coalition space until the tide begins to turn.
