Regen

The movements become faster and larger, when suddenly a Black Dragon emerged from the lava lake!
The dragon roared and shouted "Who dares disturb my sleep?"
Whats going to happen to Leonard and Regen?

In front the Black Dragon, Regen's body shrunk because he was very afraid.
Leonard said: "O mighty Black Dragon, we come here before you bearing a message from the Crystal Lake's Unicorn"
The Black Dragon responded: "Hoo.. That old friend of mine sent you? No wonder I sensed his aura on both of you"

Will they be okay?
