The enlightenment era
0>400
During the Enlightenment era man and god walked side by side in the material world of Neveria. During this great time of piece gods shared with all species the way of the arcane and many great technologies to allow the world to develop. Magic was also very abundant with almost everyone being able to cast magic or create many magically imbued items.
War between man and the under dark
400 > 500
Hadar sensing the concentration of magic in the world sorted it out to feed on and replenish his power. After making some deals with Devils he raged a mighty war against Neveria and the Gods that inhabit it.
The Great Divide
500 and beyond
After many years of war the Gods band together and decided to imprison all the Devils invading Neveria and Hadar. Some have been trapped in large crystals you can still find to this day and others to be trapped in helpless bodies to roam the world indefinitely with no way to rule it. The Gods knew that this will happen again and decided to split apart and go to their own realms. Ever since the Gods stopped living on Neveria magic has not been as strong, but you can still find magical pieces of the forgotten era with immense strengths hidden in the world.
