Note: Historical Timeline all times before Third Era are approximate, as a lot of the historical record is lost.

The first era was the era of the immortals, dominated mostly by The Iylari and Uruk-Hai, with their long lifespans to gain personal skill and power.
But in the wars at the end, their slow breeding-rates eventually cause the “lesser” races to grind them down with numbers.

In the second era, after most of the immortals had died off in the wars. This saw the raise of quickerbreeding races and unlife. During most of the era, the forces of life and unlife were about in balance. Towards middle and end the dragons with their tremendous power gained more and more power, but in the magewars to the end, they saw the same problems as elves and uruk-hai in first era, with their slow rate of breeding, they lost too. But the greatest loosers of all were unlife, loosing most of their strongholds and areas

The begining of third era was a time of unprecidented growth of life. This time the fast breeding races like common men and goblins and lesser orcs saw a great dominance. With unlife forced to shadows mostly, and the longerliving races low in numbers, the domination of the worlds was in the hands of the “common” races.

But then the unlife rose and threatened the races of life and there was a huge fight between life and unlife.

People are starting to call the time after the great war Fourth Era. It is not know what all happened at the end of Third Era yet.
