A/N: This is my first OC story, so I wanted to get some reviews on what people thought about it. I put a view summaries of some of the chapters I'm writing, let me know what you guys think about the plot so far.

Chapter 1 – "Fool's Errand"

Concerned by the possibility to losing her sister again, Princess Celestia sends Twilight Sparkle to request the aid of Chester, an eccentric clown known for his talent of helping ponies with troubled hearts. The wacky unicorn convinces Twilight, Luna and the rest of the gang to perform in his circus to lighten Luna's heart, but plans quickly spiral out of control when a band of rogue changelings decide to crash the show.

Chapter 2 – "Fool's Errand Part Two"

Ashamed by her rampage as Nightmare Moon, Luna runs away, unknowingly followed by Chester still intent on helping her. Meanwhile, Twilight and the gang try to deal with the pesky changelings still terrorizing the circus.

Chapter 3 –"A Promise Part One"

Able to convince Luna to return home, Chester prepares for a secret show meant to show Luna the good she brings. However, Twilight and her friends notice a strange change occurring to the ring-master.

Chapter 4 – "A Promise Part Two"

Having discovered the magic spell cast on Chester, the group rush to help Chester convince Luna to return for his show before the Clown King loses himself. Meanwhile, Celestia recounts the story of Jest to Luna; a depressed performer that Luna helped to become a performer again and becoming Chest the Clown King.
