Event: The First Children and the Gift (After the creation of the gods)
The gods had created the world. Io created an enormous sphere of rocks, and put it in space. This place was simply called Home. Ae then encircled this sphere with air, preventing what was inside from leaving the sphere, and protecting the sphere from the void beyond it. Finally Uy gave birth to the seas, oceans, lakes and rivers, creating the conditions for life to appear.
Plants and animals appeared all over Home, but Uy thought the world needed more. She talked about this with Io, and they decided to create a new life that could understand the things around them.
Uy took some mud from the shore of a river and casted it into humanoid form. This way she created an statue of a what would be later known as a human. The statue was of great height, and when Uy infused it with life, it broke into twenty-two pieces that became the first humans, fishermen that prayed to Uy for help and to give thanks for the new births.
Meanwhile, Io had gone to the forests and volcanoes. He took obsidian, and created a number of statues with it. He then bathed the statues with the blood of several beasts that wandered the woods and prairies. This way he created the black skinned orcs by creating the first seven of them. Three females, three males and a shaman, who would be instructed by Io to guide his people.
After a while, Ae finally noticed the new mortals. He was envious of these people who worshipped his brother and sister, and he created his own worshippers. He took the lightest leaves from the forests and the winds that blew in the world and created a fairy like race of winged humanoids, the Shidhe. However he was afraid that his new creations would not be able to compete with those of his siblings, so he gave them a part of his power. He gave them the Gift of Magic.
When the races met each other, this created conflict, as the Shidhe reagarded both orcs and humans as inferior to them. A war would have started, and the Shidhe would have enslaved the other two races, but Uy and Io told their brother that he had gave too much power to the Shidhe. He saw this, and they used their combined powers for the first time since the creation of the world.
They took the Shidhe's power, and then reallocated it, putting it inside the world, making it move inside all species. This way each race would have a small part of this Gift, with a small percentage of their populations having it. The Shidhe had the greater number of Gifted, but the war would had been impossible to win, and a treaty was made.
This way the first races came to be, and the Gift was created.
