This epoch starts with humanoid creation and goes to the end of the great war.
During this period, humanoids lived together in Eriu, and Ebru was the capital. There was a single king, Ceartas, who ruled over the mortals teaching them everything they needed to know to live in a society. There was no region, no dialect, and every member of every species lived together. The writing system was based on hieroglyph, and it was considered a sacred language (side note: hiero, from greek, means holy) because it was developed by the god itself, and used by every mortal.
It was a very peaceful period, until Ceartas died: there was a big concern about who should have been the new king, because it should have been chosen from a member of the 5 species, and every species wanted a member of their own kind as a king, except for uzats: they believed that the king could have only be a deity, so they wanted a new type of government, Since they could find an agreement, the land fell into disorder, and they started a war. Every species chose its own territory where to live, and they united against other members of other species, except for aislaan: they barely had any interest in this war, and so prefered to live alone in the desert, where they would have been more protected from any attack. Because of this "isolationism" every region slowly developed they own society, their own government, and they own dialect too, but the main language was the same. This war lasted almost 100 years, but it wasn't a everlasting fight: there were long periods of what we could call a "cold war", interrupted by great fights, mostly for occupation reasons: every species, in fact, every species slowly defined the borders of their territories, but (except for aislaans who only defended themselves) everyone tried to expand themselves.
Eryams retired themselves in the west part of the island, where they could attack their enemies in the woods, avoiding battles in large camps, in which uzats and orudels excelled. Icryses decided to settle in the northern island, to be more protected from enemies attacks. Aislaan, as we stated before, prefered to live peacefuly in the desert, and if anyone would have tried to attack them, they would have run in the midle of desert, letting the heat kill their enemies. Uzats and orudels kept fighting in the central area of Eriu, since they were both great warriors and excelled in open area fights: Orudels were physically stronger, and uzats had better military strategies, but none of them could prevail.
After almost one century of fightings, every race lost their interest in the idea of ruling over Eriu, and they prefered to divide the land into regions where everyone could live peacefuly. Almost everything stayed as before: Eryams stayed at ovest, icryses isolated at north, aislaan at east, in the desert, but uzats and orudels couldn't find an agreement: orudels and uzats couldn't get along too well, uzats didn't want to leave Ebru and the lands around it, because they were soul bounded to that city since the god lived there, and because they didn't want anyone to sit on his throne. In the end, orudels moved to the southern island: they could have used their physical strength to dig into the mountains, and uzats gained to live in the central area, as they didn't want to have a new king. After this terrible war, 5 regions were created, and every region subscribed a non belligerence pact, and if a region would have moved war to another, the others should have helped the one under attack.
The pre-dynastic period
This epoch starts with the end of the great war, and it's the current era of the world.
The writing system transformed into an alphabetical one for convenience reasons. Now that everyone found out their place in the world, every species started refining their own society, trades spread all around, and the isolationism of the previous period was over, though, obviously, some racism against members of other races was inevitable.
