Long before Twilight Sparkle unwittingly mediated the reunion of the two sisters, there was one who kept the sisters on good terms with each other. As she works to bring him up to speed with modern society like she did with princess Luna, she learns some lost history of Equestria and, more importantly, she learns a lot about her new place among these three beings from the old legends.

This story has the ponies as humans. Everything that has transpired in the series through season 2 happened all the same.
