[ WP ] Aliens come to Earth in hoping to wipe us out and take over the planet , but are honorable and gives us a fighting chance . They announce they will return in 100 years so as to give Earth a chance to prepare and defend itself . Neither side expected what the other would bring to war

One hundred years is a long time to wait. I had been part of the plan from the beginning, in my own way, I suppose and never really gave it much thought until now. Humans have never been known to take a backseat and let life happen to them. Proactive. Inventive. Impulsive, you might say. But never passive. Waiting for something to happen itches at something very human. Very evolutionary. The pressure of time and the crippling weight of a terribly limited existence is the best motivation in the universe. Humanity had been given an expiration date and a desperate species had been backed into a corner. Life will do whatever it must to survive. 
 
 So hidden and secret, created of desperate science, birthed by machines smaller than dust, smuggled and assembled from particulate cosmos, and fueled by a deep, yearning lust for perpetual existence. For years we have been building ourselves. We machines of dreadful violence. Inside of their defenses. Inside of their homes. An army of humanity's perseverance that will not allow others to dictate our end. We wait for the signal to carry out our mission and then we will wait no more.
