Meanwhile, somewhere along the border...The sun was setting, when a mysterious object fell from the sky, seemingly trying to regain control of it's trajectory, but it went to fast for anypony to inspect it for sure.
The strange thing crashed on top of a cliff, revealing it to be a strange blue police box.
The doors swung open, a cloud of smoke and a strange coffee-coloured pony stepping out, wearing a green tie.
"cough, cough... bloody hay.... what just happened?"
He turned around, looking very surprised at the sight of the spacecraft he just stepped out of.
"AGH! The TARDIS!"
He ran around, not really knowing what to do. The box was fine, just slightly damaged by the fall.
When he realized he couldn't do anything, he inspected his sorroundings.
"Where the bloody hay am I?"
He saw a small guard post in the distance. He sighed.
If they were ponies, he was safe. Him and Celestia were good friends, and he really didn't make any enemies in the previous history of the species. Anything else, he might have been in trouble.
He started walking towards it, when he suddenly stopped.
"Oh, I nearly forgot!"
He jumped back in the box, and came out with a flashy metal stick behind his ear.
"Off we go, then!"
