I am He as You are She as You are Me and We are all Rule 63'd
Prologue: A Spell
Twilight was anxious, no two ways about it. Princess Celestia had told her to return to Canterlot, and had only said that it was time. Time for what? No explanation had been given, which wasn't all that surprising, considering that she was Celestia. Twilight was outside of the door to the palace's Grand Hall, and was almost hesitant to enter.

Before you ask me why you've never heard of it, let's just say that I hid it away. Now, in order to avoid having to teach this lesson twice.,," Celestia's horn began to glow, and a bright, swirling vortex appeared. Out of this vortex came a lavender stallion with a choppy dark purple (striped with lighter purples) mane and tail, purple eyes, and… My Cutie Mark… I'm not bad looking, if I say so myself. thought Twilight (and probably this stallion as well, being the same pony and all).
"Twilight Sparkle, meet Dusk Shine…" said Celestia.
"And Dusk Shine, meet Twilight Sparkle," said Solaris.
