What happens when you create a story?
Years ago, Luna Umbra was a young artist and writer who created a story and universe all of her own. However, as life continued she was unable to continue her work on the story and settled into a normal, rather boring life with her adopted sister and wound up working at an advertising firm.
But one day, everything goes wrong when creatures she created appear in Canterlot with the intention of going after her. A mysterious woman who resembles the hero of the story appears and gives her the ability to fight back.
Now, Luna must stop her own creations from hurting her and the city. But what is really going on here? And why are they appearing now?
