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"

Leonard answered: "The Unicorn told us to get the Essence of Fire from you, so we can save the forest from becoming a wasteland"
The Black Dragon raised his hand and a red firing stone appears.
"So the Unicorn sensed it too. Danger is coming to this forest. Thats why he sent the two of you to me"
