Octavia is Equestia's well renown player of the cello. But, her history and family is remarkably unknown. Not even to her Marefriend of conflicting tastes, Vinyl Scratch. Octavia has long kept a powerful and horrendously dark secret from all, but Princess Celestia for some reason. Octavia has held the great secret, that she is Roxanne "Inky" Pie, lost sister of Pinkie Pie. Octavia would do a good job holding on to this secret, but as of late, a conbinsation with Vinyl has unintentionally unearthed this secret, and other things not meant to be heard. This is that story.
