Dragon Roar.

Valerian heard this roar, but he did not stop killing the people in front of him. The people from the Lunake clan picked up their spirits and then all began to put up a protest. Valerian noticed this and said to the leader of the Lunakes, "So this is your trump card? This beast that you think will be your guardian. You are willing to trust this thing with your life and the life of your entire clan? How brave of you." 

The leader of the Lunake clan snorted and said, "You were just now questioning whether I am a man or not. I will question you now, I dare you to wait and face our guardian." 

Valerian smiled and said, "I thought that you will never ask me to fight. I thought that roar is the best that your guardian beast can do."
