Well, technically KKAT wrote the original work, Fallout: Equestria, with LittlePip as the main character of that one. Project Horizons just expands upon it, and this piece is just showing off THAT fic's author with their characters.



If it were Kkat in a piece like this you'd see Steelhooves, Velvet Remedy, Calamity, Pyrelight, Zenith and of course Littlepip. Maybe a few other's too, but those were the main characters.
