1st age: age of old
unknown timespan
Creation of the first planes and mortals

2nd age: age of the great empires
unknown timespan, probably one to three thousand years
Rise of the first larger nations, huge development in magic and early magic-tech

The Fall of Magic
The dark god Oi'Tovon ascended and took mortals' inherent magic with them. This was followed by a decades-long conflict known as the Fallwar, which only ended once Ysra made her sacrifice to keep gods out of Materium

3rd age: age of the dwarves
about five hundred years
As the dwarves lived underground, where the War following the Fall didn't affect them as much and as they relied more on craftsdwarfship than sorcerous magic, they managed to keep their empires intact. Two huge empires - one on each continent - ruled Materium. Their cavern cities spanning basically everywhere. During this time the elves were driven out of Initium in large numbers and were given their own nation to settle. The dwarves ruled the surface and relied upon levies for their food. As the surface rebuilt from the fall and rebelled against the dwarves, the empires eventually crumbled, most of the cities being deserted and technology was lost.

4th age: age of rebuilding
682 years
This period is characterized by the chaotic state of culture and society. Various rulers established nations by military might that quickly fell again. Through this chaos much of the previous technological and cultural heritage was lost. On Eldask this era was dominated by the rise of the Alran Empire and its conflict with the faresia.

5th age (current age): age of stability
so far: around seven hundred years
The philosophy of Darton of Osherin spread and lead to an increase in stability in existing governments. Due to their adaptability and relatively high birth rates, humans spread and created the largest nations that are currently around. Humans are the most populous race of Eludan and are found in all corners of the world
