Very little records exists before the golden age other then the scrolls of Isiv that writes about the gods and the beginning of all creation.Many books were destroyed ,Burnt and generally lost about this time, the need for survival was so strong that so much knowledge was lost.
These years were the darkest as the Uruk horde has taken every realm to its knees.Villages were burned and great cities were sacked. Hope was gone and the light of civilization was flickering out.
In a sliver of a second 50% of all life disapeared as well as 100% of all memory before this moment.
This was the age of hitting the Uruk back and applying as much pressure as possible
In the early stages of he Crusade it was slaughter for the Uruk as they were confused and routed, this gave the people hope and purpose.Young Knights became instant heros and the combined armies of all people were able to push the Uruk right back to the Khazadur Mountains.
