The Doctor took a piece of charcoal and marked his foreleg. Then he turned around and saw Sparkler. He heard a thud behind him and he turned around to see his fob watch rattling and a piece of paper on the floor. He walked over to it and picked up the watch and paper, he read the note aloud, "return yourself to this forum and we will ensure your safety." The Doctor got a puzzled expression. He turned the paper over and saw "237 B.C.R."

"What's B.C.R.?” He asked Sparkler.

“It stands for Before Celestia’s Reign” Sparkler told him

“So it’s a date, 237 years Before Celestia’s Reign. Do you happen to know what happened that year?” He asked turning towards Sparkler.

Sparkler thought for a second “The only thing I can think of is that it was the second year of King Sombra’s rule over the Crystal Empire”.

“Hello!” Derpy’s cheery voice rang out as she landed.

“Where’s Derpy!” the Doctor demanded.

“What do you mean?”

“Please, Changeling, you aren’t fooling me, release her or I will be forced to take action against your hive.”

“What? Where? I don’t see any Changelings” Derpy said looking around.

“You aren’t fooling me! You got the hair off, and the ears are the wrong shape...”

The Changeling dropped Derpy’s voice and said “Who are you to think you can defeat a hive of Changelings?”

“Well, let’s see if this works. I’m The Doctor and…” The Changeling instantly flew off with a wild look in its eyes.

“I don’t get it, why’d it fly away like that?”

“Well I’d wager at some point in their timeline I had to deal with them.”

There was a sound as the trashcan in between the two houses fell over and Derpy stumbled forward. She would have fallen if Sparkler didn’t use her magic to catch her. The Doctor ran over to her and pulled out his sonic screwdriver and scanned her, she’s just a little tired. The Changeling must have drained her before he took her shape.”

“What happened?” Derpy asked, her right eye focusing on The Doctor.

“You were abducted by a Changeling on a food gathering mission.” the Doctor explained to her. “Don’t worry we scared it off.”

The two of them took her inside. The entire time The Doctor was wondering about the date that had been written on the back of the paper. The hoofwriting wasn't the best, could Lazarus have written this. He shook the thought from his head and just in time for Derpy to bolt upright and turn to him.

"The Changeling told me to tell you something..." She began, then turned to the aroma of muffins coming from the kitchen. "Who's making muffins?" She asked.

"What did the Changeling tell you to tell me?" The Doctor asked.

"Oh...Umm...She told me to tell you 'The Hive never forgets'."

"So want to go back in time with me?"

"Only if we bring Sparkler and Dinky."

"Why!" He asked then looked around to make sure that the kids didn't hear him.

"Because you left them here alone for three weeks!" She yelled sternly.

"Fine, but they stay in the T.A.R.D.I.S."

"Agreed! I don't want them to get hurt."

After coaxing the kids back into the Tardis the Doctor went and set the date. The Tardis started to shake violently and after some dangerous jerks they came to rest.

"Nice flying Turner" Sparkler said sarcastically.

"Well This particular model was meant to have six pilots, besides I've had worst trips." He said as he walked out the door.

"So what are we doing" Dinky asked.

"Some pony wants us here so we're going to wait for them. It helps that we landed in a market. Here's a few bits, go buy something nice." He said looking around.

Of all the places for her to be, why here? The grey blue pegasus stallion thought to himself as he walked through the market. He suddenly got blindsided by a little purplish blond unicorn that ran by, he tripped over her and fell on his face. His eye patch falling off his eye, he got up and walked over to it, there was an inscription on the inside, Stormy Horizon put me on. And he did just that, immediately all the memories came back to him in a flash.

"Sorry Mister" a young light purple mare said to him.

"Pardon?" He asked.

"For my sister, she was the one that tripped you and I'm apologizing for her."

"Oh well that's fine. Actually you could pay me back by telling me if you have seen a grey pegasus mare with a blond mane" he said his voice full of hope.

"The only one I can think of is my mom..."

"Do her eye's look in different directions."

"How did you know that!?" Sparkler yelled in surprise.

"My employer sent me to fetch her and her companion." He said.

"Well... Fine..." Sparkler hesitated.

"Great! You saved me a day of searching" He said walking after her.

She led him to Derpy "Hey mom! Where's Turner?" She asked.

"Oh he's over there looking at watches, who's your friend?"

"Allow me" Stormy said Bowing his head taking her hoof and kissing it. "My name is Stormy Horizon, former aid to the Empress of the Crystal Empire, before...before...", He was shivering now "Sombra took it."

"Oh.”

"Derpy who's your friend?" an overly cheerful voice rang from behind Stormy.

Immediately Stormy turned around and sneered, "You! Why is it wherever I go I can't escape you!?!?" He shouted even more agitated. Suddenly he fell to the ground as though he was hit he got up and shook his head. "You could have told me who it was I was supposed to fetch for you!!!" He shouted out to nopony in particular.

"Your eye patch, it's really an eye drive isn't it?" The Doctor asked grimly.

"They told me that you would know what it is." Stormy said sneering.

"So then. What do your Masters want?"

"There is an enemy that threatens all of Equestria and the Silence wants you to deal with it."

"So the great and powerful Silence needs my help to beat a greater enemy? Well then, who is it?"

"It must be Sombra" Sparkler guested.

"No, he is of my Masters' doing, he is there way of weakening the enemy. Doctor the enemy you face are known as the Cybermen."

"You mean Cyberponies?" The Doctor corrected.

"No I mean 'Cybermen' they resemble weird bipedal creatures in armor..."

"So why haven't the Silence dealt with them..." He rubbed the underside of his chin, "that's right the Silence use electricity as a weapon. Guess all your Masters could do is ensure that the batteries are charged."

"You speak the truth and I fear that my former home isn't the going to survive the ordeal..."

Sparkler interjected, "you said that Sombra was 'of your Masters' doing' what did you mean by that?"

My Masters know that the Cybermen have one major weakness. That is if they feel any emotions at all they will self-destruct. So they manipulated the Crystal Empire into generating a lot of love. It didn't work, and now they are tying depression, by the means of Sombra. The only problem is that Sombra has become too powerful for them to control him anymore, sure he still forgets they exist, but he is immune to hypnotic suggestion."

"So they ran out of options and are turning to me?"

"Yes Doctor, they cannot fight the Cybermen and it doesn't help that the Cybermen know they're at war with the Silence."

"So now I have to beat the Cybermen while I look like a pony."

"Yes and I am to guide you to their last known location, then I will take my leave of you.”

“Then lead on” The Doctor insisted.

“We’re in luck that you appeared here, they have been hiding in the forest to the East.” He Stormy said pointing eastward.

“Allons-y!!!” The Doctor shouted as he ran off, away from them all towards the forest.

"I did what you asked; now allow me to return to my encampment.” Stormy said not directing the question to anypony.

“That wasn’t our agreement” Stormy raged.

“No! I am at the end of my servitude!! I was promised freedom after I sent him on his way.” He yelled and then there was a smacking sound and he disappeared.

“Where did he go?” Sparkler asked looking around.

“I don’t know.” Derpy said looking with her.

“There he is!” Dinky said pointing to a freshly made hole in a brick wall.

The Doctor was already there. He pulled out his sonic only to have Stormy knock it away, “I’ll be fine. Don’t bother doing that again!” he sneered getting up.

“What happened?” Derpy asked lighting down.

“My Masters happened.” He said, lifting a brick off his wing, “No Let’s deal with the real threat.” he said getting up and heading towards the forest.
