Villanelle Lyric has been selected as the only pony in Canterlot to write a personal and in depth biography of Princess Luna and Celestia, and takes her duties very seriously. Her duty is to stay in the castle with the princesses for a year, interview them on their pasts, and detail everything they do daily. It's truly her dream. That is, until ghosts from Luna and Celestia's past reveal themselves in Villa's dreams. Each of them a victim of the sisters' recklessness, stubbornness, and pride. Now they have things to say. Things not even Villanelle should know.
