For as long as Rainbow Dash could remember, her life was simple, straightforward, and planned out with one goal in mind: become the best flyer in all of Equestria. Simple. But when she unwittingly comes across a tool that allows her to relive the memories of her ancestors, that simplicity is challenged when she discovers dark secrets hidden in her family's past as well as Equestria's history that not only challenge her perceptions of reality, but threatens to alter her very psyche.

As she's thrust into the remnants of a centuries-long war, as she questions the morals of those around her, as she battles to separate reality from fantasy, will Rainbow be able to hold on to her own beliefs or will she embrace her family's blood-stained traditions and finish what they started?
