"Once upon a time, in the magical land of Equestria, there were two regal sisters who ruled together, and created harmony for all the land. To do this, the eldest used her unicorn powers to raise the sun at dawn; the younger brought out the moon to begin the night. Thus, the two sisters maintained balance for their kingdom and their subjects, all the different types of ponies.

But as time went on, the younger sister became resentful. The ponies relished and played in the day her elder sister brought forth, but shunned and slept through her beautiful night. One fateful day, the younger unicorn refused to lower the moon to make way for the dawn. The elder sister tried to reason with her, but the bitterness in the young one's heart had transformed her into a wicked mare of darkness: Nightmare Moon.

She vowed that she would shroud the land in eternal night. Reluctantly, the elder sister harnessed the most powerful magic known to ponydom: the Elements of Harmony. Using the magic of the Elements of Harmony, she defeated her younger sister, and banished her permanently in the moon. The elder sister took on responsibility..."

"…for both sun and moon, and harmony has been maintained in Equestria for generations since. Doctor, where is this Equestria?" Donna Noble looked up from the book she was reading.

The Doctor was in the TARDIS with her. "Equestria? Oh, it's just a legend. You know how those My Little Pony toys got on the shelves way back in the 80's? Well, I helped. If I remember, I was with Peri and we were trying to stop Tirek at Midnight Castle, then after that, all those ponies turned on me. I swear, that Megan Williams still hates me 'cause she thinks that I kidnapped her 'distant cousin'. Hey, she walked into the TARDIS, she wanted to join, that was fine with me."

"So, you had a history with toys?" Donna asked the Doctor.

"Well, sort of. I remember back then, the ponies used to live in Ponyland. Must be a heck of a long time for them." The Doctor looked at the TARDIS scanner. "Wait a minute, that's not right!" Donna came over to where the Doctor was. "We're in the Equine Zone and there's two small planets down there, quite a distance away from each other. Well Donna, you wanted to know where Equestria is? Well then, allons-y!"
