Surging Current.

Valerian had no idea that Bloomkin had met the queen of dragons. His mind was occupied with thoughts of the battlefield, and at first he was in pain over what happened. However, when he thought it over, he arrived at the question, why did he do what he did?

He wanted to find the reason behind this, but he could not arrive at a conclusion. The boy was lost so deeply in his thoughts that he didn't even notice when he got to the Lumen Imperial Palace. Linea was tired from the journey, it was the first time that his master did not tell him to rest, and sensing the turbulent emotions of the master, he did not ask him anything. 

Only when they landed in the western garden did the beast say, "Master, we have arrived." 

Valerian woke up from his daze. He looked around and realized his location. Then he got off of Linea's back and said, "Take rest and eat well."
