You've grown up all your life being told that when you turn 18, you will have a dragon come to you that is connected to you by fate as your partner. You wake up on your 18th birthday, heading out into the forest. As you relax underneath a tree, taking in the nature, you see a bright flash of light in the sky. Out of the light comes a huge, muscular but slim blue dragonman wearing blue baggy pants with a red belt tied around his waist. He lands in front of you, looking down at you with a gentle smile.
"Hello there. I'm guessing you're my human partner?"
