Solve This Riddle: Twist And Turns my master plan, then find the elements back. Where Du began.

This is from MLPFIM and it means to return to Ponyville.
This was a great episode (The Return of Harmony Part 1)!

I don't get it and when I Googled it, it lead me to a “My little pony” roleplay

It leads them back to where they got the elements in the first place in the bibliothek which Twilight Sparkle runs in the elements of harmony book.
