Ashina the Son of Winter

But when Aeryon hear the story of the four wolves, he is not sure whether the story is just myths or whether it is the truth

Because the world Aeryon is living in, is a world that once had magic. 

The evidence of that magic could be seen everywhere all over the Steppe. 

From the Empatarah river that defies rules and from the many large caves near the mountain of Yindu, from the many other unexplainable forbidden places in the world.

So, he could not be sure that the stories are just stories or it might that they might be true

The story goes that there was a child called Ashina. Ashina was the son of winter. And he was raised by wolves.

No one knows the parents of Ashina. Hence in many stories, he is called the Son of Winter, for his story began in a winter snow, when the wolves found him and adopt him. 

When he is a child he spoke with the wolves and when he could stand, he wrestles with wolves and bears.
