There are many things in the world of My Little Pony that we don't understand no matter what the show tells us.
Why are the Ponies responsible for how nature works?
Why Celstia and Luna control the sun and moon?
What is the Tree of Harmony?

I don't promise you answers to these questions. But there is one place where you can look for them.
When science fails go to legends, myths folklore. Those who came before us asked the same questions and made their own answers.

Tell Tale the Traveling Storyteller has come to Ponyville. A bard that has knowledge that books might omit. Join him and the Mane Six as he brings you the one thing I've myself been missing in the show.
Folklore.

Idea, concept, writing and (somewhat) edditing by me.
