After a short life of 5 years in his birth settlement on a continent far into the west sea, he follows the natural call of his kind to explore the world. But he wanted to see further more than most of his people.
 
He meets a stranger from afar, called Jafar. He was a mage of the Crestbound Tower, and he saw in Yu the needed thirst of knowledge to make him a wizard and propose a formation, Yu, of course, accepted and learn the ways of magic at the Crestbound Tower for 20 years, after that the call of exploration became too strong to stay at the tower and went to the eastern continent.
 
His trip to the continent full him joy and amusement at the sight of all the new ways of living, but a displease also grow in him. The displease of seeing parents living with their children for such a long time. Why he and his kid couldn't get the joy of travelling with your family?
 
After this thought, Yu's travel became a pilgrimage to find the way he could change his entire kind to meet his wish.
 
Yu lived around 10 years in the city of Silverstream, where he room in the Marketplace Isle and the Academy Quarters, questioning everyone and reading everything he could to have a clue to accomplish his goal.
 
As soon as he discovered that the answer was not here, he went to the academy of Luminae in Brighthome and stay for around 3 years until he was sure that his answer was not in here either.
 
After the two cities and no clue or advancement to his goal, he understood that he needs to find or even create the answer and not wait for it.
 
For this purpose, he decided to stay at Harvestbrook, a little town almost at the center of the continent, not too far from everything a good place for his research base. Soon, his home became full of useless books for Yu, but not for the village. So he opens a library for the town.
