Story line for my game - Tell me what you think

This is the story line to my upcoming game, tell me what you think of it, tell me what would work, what wouldn't work, what I can add to it etc.

Over countless millennia, people talked of a war so great it changed our planet forever. When the people spoke of this war, they spoke only about the death and destruction it brought to this planet. They talked about how cities, towns and villages fell completely defenceless. About how local Governments were thrown into utter chaos. On that day, they said, everything was lost forever. It was said that the war was the worst calamity ever to plague the planet. The people spoke of an end they thought would never come....

Then, without notice, the entire war just ended. Over time, people talked about the war less and less until it was eventually taken from their memories. But, not all had been forgotten. Those who survived spoke of a Man so great, he struck fear into the very heart of the enemy. The Man, they said, had no name. They said he just appeared alongside them one day. The survivors talked about how this Man would just walk up to an enemy base, and destroy it with one fell blow. They eventually began to call him 'Parusa' after the name of the first enemy base he destroyed. When asked what this 'Parusa' looked like, they described his orange hair, his armored suit and his immense power. Ever since that day, 'Parusa' became known as a hero. Now, every 500 years, on the 7th of march, a baby is born that greatly resembles the hero of old, Parusa. When the baby turns 20 years old he or she is required to go to Molwat Castle to see the king, who will then set them a task for them to finish. This is the story of one such baby on his 20th birthday. This is the story of Aldren Tempest.

It's a decent beginning, but tells us very little about the game itself. What's it about?

Also, orange haired Parusa better not be Arshes/Aluxes... <.<

The game's storyline will be revolving mostly around this war, which will eventually come to be known as the war of ages.
The return of an ancient evil at regular cycles plays an important role in the story. (The ancient evil is what started the war in the first place) An important bloodline plays a prime part in this game. And no, Parusa is NOT ARSHES! But I'm not going to reveal yet who will play Parusa's part. And there will be a betrayal too.
