Not many ponies know this, but Daring Do always leaves her most valuable treasure behind whenever she goes on an adventure. And that treasure is you, Anonymous, her adopted human child. She's never gone for too long anymore though; not with you in her life. Or, at least that's how it was.
Eight long years have passed since she last flew up into the sky and out of your life to go on another adventure; almost half of your whole life. And yes, you did spend a lot of that time worrying, and wondering about where she could be, or what could've happened to her, but you also spent it honing your own adventuring skills. And now you're all grown up, and you're going after her.
With the wisdom of six good friends, determination in your heart, and mom's lucky hat on your head, there's no way that you can lose.
