Equestria's Royalty in a group or alone. Twilight Sparkle is only included if it's in a group with the other royals, for she has her own folder already. Shining Armor is considered Royalty due to his marriage with Cadence. King Sombra and Queen Chrysalis, while royalty, are "Major Villains" first and foremost. Blueblood's lack of importance in the series sends him to "Minor Characters and Other Creatures".
