The story takes place in the age of machines where humans have understood and mastered the metal of the machines. It all started when a human look alike robot was made.
They can wield the power of metal and electrons to a level that it can be integrated into the flesh of a human. Combined with the metal, a human can perform actions equal to the work of 1000 men.

Everyone were convinced and converted into a synergic machines .even to the
level of the micro-cells.
People loved it. They loved the power they had, the immortality offered. Because now they only needed, electricity and metal to survive.
As wise men said,  "Men who have power, have only one wish..more power"

True to this, the whole human-machine race turned from Industrial age to the new cyborg age. Now in the deep dark metallic hearts of all men only one thing resides, destruction and power. The world was torn apart for power. Cyborgs formed and broke alliances. There was no trust between anyone anymore. The great cities of men turned into colonies of cyborg groups. They fight each other for the scrap metal left out. They get their energy
from the sun during the day.
In the far east on the highest peaks of himalayas, were left a few men who did not combine their flesh with metal. They were left out as rodents by the cyborgs. An oracle who knows how the tide of life cycle goes about resided here.
She prophesied one thing before this cyborg age started.

"When the Sky turns dark, the weak cyborgs will follow the one
who leads them to salvation and a new hope".

This saying was known to every cyborg alive on the planet.

Many cyborg emperors rose to power with the claim that they were the one who will lead the cyborg clans and unite under one banner. But all they brought about was more destruction and more clans who fought among themselves.

Many 100's of years passed. It seemed the cloud of fire and smoke were dancing forever. But one day it all changed.

The skies were covered with dark clouds and the the bright day got dimmer by the minute. The cyborgs were losing their power by the minute as this happened. And even before any cyborg realized what was happening, alien ships covered the sun and blocked the planet.

The oracle prophesized this long ago.
"...and out will emerge the dark lord with vengeance and total destruction"

And she also said
"The fallen ones, look down."

The cyborgs unable to take the torment of the alien vulceons, go underground the earth and the ocean and will use the heat of the earth to stay alive.

The humans have been on the face of earth for more than 5000 years. They evolved from stone age - machine age and are now in the age of magic. Through ages of research, humans have accomplished the highest mental ability and improved their skills in it. They surpassed the need of metal and entered into the age of what others would call as mystery or magic. They communicate with telepathy. They can live on simple and very little vegetation. They use the power of the 5 elements (earth, fire, water, wind and air).They can focus the power of the nature and life around them to destroy or to create. They shield themselves from external forces using mystical mental connection that can spawn an aura around them. These are the humans who have resisted the conversion to cyborgs and fled to the Himalayas and attained the ultimate power and peace. But can they survive against the vicious aliens ?

Machines (Metronites/Cyborgs (metal-electron beings) ) : They are composed of metal and electricity. They use these 2 resources to power themselves. They can equip themselves with a range of attacking weapons. It ranges from missiles, plasma cannon's, ion beamers etc. They are also well defended. Their armory consists of the fusion of metals on their skin. They can start with simple iron to the most powerful metal tungsten. They can also upgrade to radioactive skins that can damage biological enemies (the other 2 races).
