The Nano Wars
Every few generations, a new technology is discovered that revolutionizes the way we think, even to the point of turning the tide of war. History is rife with examples of this: In the 13th century, gunpowder was discovered. In August 6, 1945 two small bombs were dropped that that immediately extinguished the life of around 200,000 people, and left countless homeless. With each new turn of technology, its effects have been devastating, long lasting, and thrust the victor into a position as a global superpower.
In the year 2015, such a technology was perfected. NanoBots: Small, microscopic computers with the capacity to heal a person instantaneously, give enormous power, or even swarm around an individual, killing him at a molecular level, all based on its owners intent. This technology is undetectable; it is far too small for sensors to pick up, and far too intelligent to be caught by a machine. This technology has been a well-kept secret during its development by the Moresian Alliance. However, the news somehow leaked to the spies in the Chaos Legion.
The top-secret and well-hidden research base was breached and destroyed during the late stages of development for these NanoBots. A lone scientist and his personal guards were the only ones able to escape the onslaught, and they fled to Earth, a still developing planet within the Milky Way Galaxy who was completely oblivious to the terror that would soon follow.
The Moresian Alliance had a longstanding treaty with underdeveloped planets, to leave them be until technology allowed them to discover their probes, and Sol was well within their dominion. However, the Chaos Legion had no such policies.
This is the story of Earth, in its pre-infant stage, discovering the truth, and rising to the fires that it faces. Will it survive the struggle? That is a fate that a few intrepid heroes will decide.
