Soon after Pinkie left, he stayed in the control room for a while. He suddenly noticed a Pink light. As he looked up, the Pink Light was fading, shutting off completely while a faint purple glow was emanating from the center-most of the lights.

Looking to the Power Monitor, The Doctor saw that power transfer had been greatly Reduced… barely holding steady at Fourty-Two Percent.

“No….” The Doctor drew back, his eyes narrowing as these facts worked over in his mind.

Six Ponies… Six new Lights in the TARDIS.

“Nooooooo…..” His tone was incredulous but in spite of the negative, his mind reeled in a giddy surprise  that came as it started to fall into place.

Six Lights… Cyan, Orange, White, Purple, Pink, Yellow.

Six Ponies....Cyan, Orange, White, Purple, Pink, Yellow.

“NNNNooooOOOoo” The Time Lord’s expression turned into a grin.

‘That’s what we value…. More than anything… our Friends. There’s nothing more powerful in all of Equestria than that bond. ’ That was what Pinkie had said in the Memory Room.

The TARDIS had been out of fuel… and sought out a suitable replacement for a basic universal energy. Something that was constant, steady, and powerful.

And in this instance, it had latched onto the most potent fuel source it could find.

“YES! THAT’S IT! Oh, Clever Girl… A little frustrating, but OH So Clever.” He looked up at the TARDIS’ Console. “You girls are ganging up on me, is that it? What are you saying? That you like them? That You like it here? Is that it?

Almost as if to answer him, there was a whirling click from the other side of the Console that brought the Doctor’s attention around.

Popping out from the console, a newly designed Sonic Screwdriver was ejected from position, a bit larger and heavier than his previous model, with a rough, ribbed surface and no buttons at all. At the top, the main projection crystal swirled with alternating colors, shifting though a full spectrum of colors as it functioned.

As he pulled it free with his teeth, he found the extra heft helped him balance it as he practiced holding the device with his hooves. It was still clumsy, but the ribs gave him a better chance than the usually smooth metal feel,  And a psychic interface allowed him a much quicker set of options he realized as he felt the Screw-Driver’s database and systems settings brush against his mind.

It was a perfect design for this new form.  

“Okay, Okay…. you made your point. Please, feel free to keep Bribing me, of course, But I get it.” The Doctor smirked slightly, turning to look at the new power gauge  again. “Assuming this is a proximity detection unit…. That would mean…”

Twilight gathered her friends and I to her home as The Doctor had an announcement.

"My friends, I have an announcement."

"Yes?" Twilight asked.

"I'm staying in Ponyville." All of us smiled at once.

"YAY! PAR-TY TIME!" Pinkie brought out her Party Cannon.

"Yes, I know. First, though, I'd like you all to see my TARDIS after it's......renovations." We looked unconvinced. "I see. I'll let you have 5 minutes to decide." He went back in and closed the door.

And before the full five minutes was up, there was a rapping on the TARDIS door.

Although he couldn’t explain it, there was a certain degree of tightness in The Doctor’s chest as he moved to the door.. Holding for just a moment before pulling it open.

And to his amazement… Seven Ponies stood there in the doorway, looking at his stunned expression for a moment before filing past him one at a time.

“I think this is the beginning of something truly extraordinary, Doctor.”

“WHOOOO! The Pinkie is HERE, Doc!  Parties across TIME AND SPACE!”

“This is going to be…. SOOOOO AWESOME…”

“Oh, uh, permission to come aboard… please…if…you know…you don’t mind… Doctor.”

“Oh Doctor… before we go anywhere too far, could we perhaps make a stop by my Boutique? I mean, what should I pack? Should I pack for cold weather? Warm?”

“Alright, Ah’ll try it, but Ya’ll better not be yanking us around by the reigns…”

The Doctor stopped me from entering. "A little birdy told me you like Sonic Screwdrivers." He waved the 11th Doctor's Sonic to me and I happily levitated it, laughing as I entered the TARDIS.

While Twilight, Pinkie and I continued in without stopping, Rainbow Dash, Fluttershy, Rarity, and Applejack were stopped in their tracks a few scant steps inside, each running into one another as they realized their surroundings.

“It’s…”

“Bigger…”

“On…”

“Tha Inside…”

The Doctor couldn’t help but grin.

“IS it? I hadn’t Noticed.” He shut the door behind them, moving past the mares at a quick gallop, excited as he reached the controls and started pressing his hooves into the large panels, biting and pulling down on a lever, then kicking  on lever slightly with the large grin apparently plastered on his snout.

“Alright Girls. Welcome aboard the TARDIS. One Quick Trip to get the hang of things and go over ground rules. Pinkie, I believe I have a promise to keep, so here we go! OH! And one more thing.... You MIGHT want to find something to Hang Onto!”

He reached over and spun a wheel with one hoof as the TARDIS shifted suddenly, rocking a bit  while the Doctor Frantically moved around the circular console.

“HI-HO TARDIS! AWAAAYYY!!!”

Twilight, having experienced this before, had already moved up against the guard railing and pressed herself too it, one hoof over to stabilize herself as the TARDIS rocked… Pinkie, being her usual bouncy self, seemed almost unaffected by the shaking, laughing all the while.

“OOhhh My Mane… EEP! Does it ALWAYS do this Doctor?!” Rarity called out, her legs shuffling to try and keep herself upright while Rainbow remained air-born, managing to ride out the shock-waves of the TARDIS’ flight.

Applejack kept a firm grip on Fluttershy’s tail as the yellow Pegasus had gone ridged with the sudden shocking movements, sliding this way and that along the transparent floor. In spite of the fearful expression in her eyes, there was a certain, contagious excitement to it that the farm pony couldn’t quite ignore.

Then as suddenly as it had started, the tremors had stopped.

“Not always.” The Doctor replied to Rarity at last, pulling himself up, slightly out of breath from having rushed around the console as he had. “But Usually. Yeah.”

“A little more WARNING Next time… Really, I thought you knew how to fly this thing?” Rainbow came down from her flight with an sour look on her face.

The Doctor waited a moment, taking the comment on his driving in stride and waiting for the important question to be asked.

“W…wh…where…are we?” Fluttershy stammered slightly, looking around.

“Well, we can’t have gone far… we were only riding along for a few seconds.” Applejack assured her, looking to the Doctor.

In Response, the Doctor merely pointed a hoof towards the door.

Twilight took the invitation first as the others found their hooves again… moving over…and opening the door.

What she saw nearly made her faint.

“Dear Luna….”

One by one, her friends moved to the doorway, each standing in mute silence as the impossible scene before them played out, The Doctor standing behind them as they gasped in wonder.

High above their heads, a glowing orb of a world of blue and green pastels, wisping white clouds dotting areas that rain had been scheduled or in areas where wild weather took over. Before them, an endless plane of gray stone and soft looking soil stretched to the edge of a horizon, dotted by small imperfections and craters while the starry black night lined the horizon.

Tears formed in Twilight’s eyes as she came to the Conclusion that Pinkie now blurted out.

“We’re on the Moon…. “

“Dear Celestia… he weren’t making it up…” Applejack stammered slightly.

Rainbow looked back to the Doctor, who seemed himself to be far more appreciative of the six mares that stood in awe of the scene before them, bathing in the light of Equestria.

“Can…can we go out there?”

The Doctor Nodded.

“I’ve extended the air bubble by a diameter of about Fifty Yards… but stay CLOSE to the TARDIS.” He warned. “If you get too close to the edge, you’ll see a blue energy distortion. Now beyond that point there is no air and no pressure… it is VERY Dangerous…so BE Careful.”

And one by one, the ponies journeyed out, their hoof prints leaving impressions on the soft surface.

“Wow… flying is so much easier here… I bet I could pull off all KINDS of tricks.”

“AHAAHAHA! LOOK! MOONWALK! DUN-DUN-DUNN!!” Pinkie bounced a bit higher than normal, gliding a bit along the surface as she ran her hooves in a backwards motion while moving forward on her hind legs, a position that would have been nearly impossible for another pony.

“It’s so…beautiful. Is that Equestria up there? I wonder where Ponyville is….” Fluttershy asked meekly, straining her eyes as she looked upward.

“Oh my… So dusty… You would think that Princess Luna would take better care of this place, she was certainly here long enough. Maybe a bit of a cobbled sidewalk or something.”

“Seriously, Rarity? Ya’ll for real? Lookit where we are… An’ ya’ll be worrying about dust?”

“Well, a LADY must maintain her dignity under any circumstances, mustn’t she?”

The Doctor followed them out, watching them go about the landscape in their own way as he approached the quiet purple unicorn.

“Not bad for a crazy pony with a box that crashes about?”

“It’s… amazing. I mean… I’ve read about it. I’ve looked up here so many times though a telescope. But… to think. I am the FIRST mortal pony…. To stand here… To…” She bounced up and down slightly, feeling the lessened gravity. “To see it up close… to FEELLLL what it’s like… to .. Whooaa.. That’s soo weird. Wow… do you think.. I might be able to take a sample back? Just for…”

The Doctor’s smile faltered for a moment, causing Twilight to hesitate

“That’s… a natural question…and I suppose it means that it’s time to go over the next part of this…” The Doctor shook his head with a sigh. “Girls! Everypony! Over here!” The Doctor shouted a bit to get their attention, striding in the light gravity with ease. “Yes, I know it’s an absolutely BRILLIANT view…but please, your attention. Something important I need to go over with all of you.”

He took a breath as he looked over the group of them, Rarity trying daintily to avoid getting filthy while Rainbow Dash grudgingly joined them.

“I’m not used to addressing so many at once so bear with me, Alright. So before we start galloping off all over the place, I have some things I need to tell you. Firstly, I’m more than happy to travel with all of you, but not all at once like this. I’m not quite used to so many to keep track of at once, so at least for now, we won’t all be traveling together like this. I can’t keep an eye on all of you and while this place is safe, there is no telling what we might encounter as we travel. So after we leave here, I’ll take you back to Ponyville and you can all decide where you would like to go for starters in groups of two or three. Any Questions.”

Almost as if this was a class and the Doctor was acting as a field trip chaperon, Fluttershy raised her hoof.

“Ummm, So, we can go ‘anywhere’ we want?” Fluttershy asked timidly, her mind obviously cast in a certain place.

“Yes.. But there are a few ground rules you all need to understand.

Rule Number One: No Average, Ordinary, Boring Days! This is a Time Machine, Anywhere and Everywhere is open to us. Every Planet that will ever be, Every Star that Ever Was. All of it New, ALL of it waiting for us. But right NOW, You have to promise Not to exploit or use it to your advantage, not to make money or pick up futuristic souvenirs to make life at home easier. This is The Experience and Adventure of a Lifetime. No One Else can do the things that we can do here and now. PLEASE… Don’t cheapen that.”

We looked at one another as Twilight bit her lip, looking around at where they were.

It was the Moon. And they were here.

The Scientist and Scholar in her wanted so much to collect samples and bring back proof of this amazing experience.

But as much as she wished to do so, she realized, in order to explain how she got them, she would have to betray what the Princess had asked them all to do, to keep the Secret about the TARDIS from becoming public knowledge.

“Rule Number Two:” The Doctor continued. “Interfering with Established Events is STRICTLY forbidden. Now, most of time is in flux, we can act here and there and it won’t impact history ‘too’ much. Contrary to popular philosophy moving a stone does not change the course of a river and a butterfly’s wings don’t usually create storms a world away BUT, There are Fixed Points, both past and future, that have, will and MUST always happen exactly as they are supposed to. We can try to avoid those, but keep in mind that this extends to your own personal time-lines, because they are what happened in YOUR lives.

That means we can’t go back to when you were a filly and tell yourself about what will happen in the future. No going back and leaving notes to avoid something that happened that you now regret. Those sorts of things gets Very Complicated, Very Dangerous,  VERY Quickly.”

As Twilight nodded, the others did the same, accepting that when the Doctor put it that way, it made sense. Twilight could see the concern in his eyes though.

These weren’t rules that he was making up on the hoof. These were things that were important to him, things that had been taught by hard experience.

And the thought of what the consequences of these things might have been made her both worried and more than slightly curious.

Then she considered how easy it would be to abuse that power.

The repercussions of such a thing sent a shiver down her spine.

“And Rule Number 3: And this is by far the Most Important. No Matter what happens. No matter how frightening or dangerous things may become. No matter what we find out there or what situation you need to remember Rule Number 3…. Remember it because one day, your life may well depend on it”

The Six Mares leaned in slightly, hanging on every word as the Impossible Stallion took a breath,

“Trust Me… I’m The Doctor.”
