A little bit of information before we begin the story.
It is the 9th Age in Arda; now called Earth.
The humans have become very advanced technologically and the elves of Valinor have completely removed themselves from the world.
Arda is now a very different place from what it used to be.
While the majority of the elves have gone during the 4th age, a few have decided to stay with the humans. By the 6th Age, these few elves have been captured and experimented on by the greed of humans. In modern society of capitalism, instant-gratification, and the search for immortality, the elven DNA is extracted and applied to human fetuses by scientists. The generations pass and humans are now a blend of both elven and human genes, they are named the Elvans. The remaining unmodified humans are called the Terrans.
The Elvans are a perfect mix of both human and elven DNA, handpicked by scientists to make the perfect beings, thousands of years back. They have the beauty, grace and elven longevity; the drive and ingenuity of humans. They live in harmony with nature and are re-growing the trees that were lost to them ages back when nuclear war raged. They have one of the Silmarils, which has been found in the ocean (when they were restoring the seas to their original un-polluted state).
The Terrans are humans who have modified themselves with multiple implants to keep up with the Elvan's long lifespan. They have grown to detest the high-order of these beings, they hide in large dwellings deep underground. They have discovered one of the Silmarils from deep-mining the Earth.
Since the discovery of zero-point energy technology, food, clothing, housing and shelter is available for everyone to use. Both races have this advantage and can change their clothes at will, create battle armor, tools and transportation with the help of small generators that hook on the body
