So, after the Quest i went to Roselia and gave her the book. She talked with me about that i need a Bound of Friendship to tame a Dragon. I dont really understand that. I go out of that Petstore and i am attacked by this Lava Dragon. I think, that its the aime to tame this Dragon, but i dont know how. So i killed him first. But every time i come out of the Petstore comes a new Lava Dragon and attack me again! Please help
