Valerian opened the box and found seven daggers laying inside it. His eyes were glued to them as if they were a treasure. The knives were shiny, with a gleaming edge. They all had different color corresponding to seven elements. On the blade a dragonhead was engraved. 

The boy was surprised, and asked, "Why a dragonhead?" 

Gellard replied, "This is my mark, if you are in need to have them repaired, then the other grandmasters will help you without any cost." 

Valerian raised his head in confusion and asked, "Why?" 

"This is a basic practice among grandmasters. Don't worry about it, we do this to inspect the craft used by the rivals.", explained Gellard. 

Valerian nodded, and gazed back at the daggers inside the box, he asked, "The cross guard is narrow than usual."
