The last race, that had its history described, were the Nerivans. They reproduced in big numbers and came into conflict with the Anomi (the 'nonhumans') pretty fast. But contrary to what every other race has done, they started a dialogue with them. During this dialogue they sorted out their conflicts.
That way the nerivan continent was divided between the different Anomi races and the nerivans. The nerivan provinces developed from this division.

Besides a description of this process, I also described how the nerivans got their laws and came up with their rules of marriage. Also, due to work on nerivan history, we came up with another major change for the rest of the world.

Yes, you've read that right! Before, the weather was controlled by some kind of deity, named Nimbur, and there was no reason for seasons to exist on Lygea. The planets rotation axis is perfectly perpendicular to the suns - yes, both of them!
But now we've found a reason for this deity to split up into 6 parts, which became the seasons. They were sitting on static locations all over the world, until they started moving in circulation after an event caused by the nerivans.
Besides Spring, Summer, Autumn, and Winter we got Silem and Wilder. Wilder brings dry storms and strong updrafts while Silem brings lulls, fogs and general gray weather.
