The Primordial Age: -3000EC to -1000EC

History of ancient days is...hard to exactly get right. While the Elves of iadith were previously fully willing to share their vast library of, incomplete but largely superior to other sources, ancient historical tomes, they have as of late barred scholars from using their libraries. That and much of the historical texts were not only lost in a great library fire but also full of the elven creation myth and so not entirely something one would consider "accurate and unbiased". However, some knowledge remains still, and it tells of an age of pure chaos.
No one is entirely sure of what inhabited the world before the Primordial Age, but it is said the age began with the World Spear piercing the world from pole to pole. While the exact date is argued upon, the current prevailing theory is the year -3000. This time was when demons were roaming the world, and if some cultists can be believed when those from the Void Realms ruled the world. The World Spear banished those from the Void, and this was also around the time the early Elven race would come to be on their island of Iadith. This age was also where Dragons were some of the most common creatures to inhabit the world, and it is said few if any of the current races who inhabit the world actually walked amongst the world.
In terms of actual events, few can say. Aside from the Elves fighting for their homeland, which would cost them dearly for thousands of years, it was generally an age of total chaos. Great beasts and dragons fought one another and the many demons that roamed the world. Great battles scorched the earth as titanic creatures did battle. Giants would cleave through their enemies. However this age would come to an end as the demons were scattered and eventually fully banished to their realm of hell, but most of the dragons and other titanic creatures were slain in the process. This was also when the first hints of many of the other races such as halflings, humans, dwarves, dragonborn, and others began to be seen.
