The Tears of Gaia. An artifact of unmeasurable magical power from the Ancient Days, when the Others ruled the land. If found, they would be the discovery of the century!
At least, those are Twilight Sparkle's thoughts. But something is stirring in lands to the south. Soon she will find that she and her friends are not the only ones who are after the legendary Tears. And so what starts as a simple research trip is soon to escalate into the greatest journey of the young ponies' lives, filled with new friends and foes, incredible danger and great adventure!

NOTE: While I do appreciate all comments I get on this story, I would personally prefer if they could say a little more than the typical "Awesome chapter, I love it!" or whatever. What do you love about it? What struck you in this chapter? What would you like to see explored or expanded? Are there things you don't think are working and if so, how could they improve?? I have a pretty determined vision for this story, but it wouldn't hurt to know for the future!

Now with a TVTropes page!

A strange blue box crash lands in the middle of the Everfree Forest to be discovered by Twilight and Spike. The Doctor stumbles out of it and makes the shocking discovery that he's accidentally traversed to another universe entirely! Ready to test his new four legs in this universe, the Doctor does what comes naturally to the renegade Time Lord; jumps cutie mark first into danger.

With Twilight Sparkle and the other Elements there to make sure he doesn't do anything too stupid, the Doctor with his TARDIS goes off to explore everything this new universe has to offer. New adventures and historical ponies await the crew as they continue to go onwards and upwards.
