**Sapphire Glow Prologue:
The Forgotten Third Princess**
Sapphire Glow the third sister of the celestial trio, has always kept them safe from harm. But only together have they every done anything amazing. Truly she has become the greatest commander of the royal guard ever. At the age of 15 she left for Crystal Empire, once Discord's rein had begun.
During those ten years she studied about the crystal heart as much as she could. At the end she found no result. After having, an artifact pierce her eye, she was hospitalized for 3 years, still continuing her studies. Since she found no avail, in her ten years of searching, she left to return to her tower.
But to only find out that, her sisters Celestia and Luna, have defeated Discord with the “Elements of Harmony.” After a year King Sombra had taken control over the crystal empire, since the relic in her eye, was connected to the empire she felt all the pain the crystal ponies were going through. Yet a month later on the day now commonly known as the summer sun celebration. Her sister Luna had transformed into Nightmare Moon. Sapphire being the type of pony she is, went off to fight her sister. After being imprisoned, sapphire was never seen again.
Yet a pony named Sapphire Shield, had appeared 995 years after those events. Now commander of the royal guard “he” will stop at nothing to protect, Celestia and her student Twilight Sparkle. Sapphire Shield has become good friends with Twilight’s older brother, Shining Armour. (Who is the current captain of the royal guard.) Since then not a single legend has ever come about Sapphire Glow, since her sister did not wish to say she had another sister that had vanished.
