It was a dark and terrible day for The Doctor. He had done what he had sworn to never do. He had gone to war, and he had killed. But that's not all. Te destruction of two great and powerful races, the end of both the Time Lords of Gallifrey and the Daleks. The last great Time War had come to a close, and after years of fighting, both sides had been destroyed at the hand of a man whose name meant healer. The Doctor had sworn never to do such a thing long before the time war. He knew it was necessary, but still it was wrong. He recalled his last words to the Shadow Architect as he sat in his TARDIS and watched as the ruins of his world smouldered below him.

"Under protocol nine two seven seven six of the Shadow Proclamation, I, The Doctor, TIme Lord of Gallifrey, do state to the best of my knowledge that the destruction of the Kasterborous Constellation, home of Gallifrey, a level nine planet, population eight trillion plus, must be destroyed entirely in order to protect the best interests of the universe at large,"

"Then you may proceed, Doctor. You will recieve no further assistance from the Shadow Proclamation. You will carry out the act yourself,"

And that's when he did it. All he had to do was flip a lever, and he would extinguish eight trillion lives in the blink of an eye, every one of them willing to die if it meant that the Daleks' insane conquest was ended. And so he did it. He killed every lest living Time Lord in existance. He flipped the lever. Circular Gallifreyan symbols flashed red in front of him, and he ran to the TARDIS to see his world burn from a brighter view. This time, the Doctor truly was alone. He had always hated alone. It was such a sad, sad word. It was horrible when you really think about it, being alone. Many of the Old High Gallifreyan scripts said that the void was so terrible because it was the loneliest place in all of time.

The Doctor was snapped back to reality as he was smashed against the TARDIS' contol unit by the pressure of a massive explosion. The entire TARDIS rocked. Alarms whizzed and whirred, and buttons flashed and Gallifreyan glyphs flared an angry red. The TARDIS wasn't in control anymore. The Doctor had flipped levers upon his falling, causing the TARDIS to enter the time vortex. He spun rapidly out of control, disoriented and slowly losing strength as the sadness ate into him. He stood, trying to put the TARDIS back into space rather than time. Suddenly, the jostling and jolting stopped. Alarms still screamed frantically, and symbols still jumped around and flashed red, but there was no movement. The Doctor opened the TARDIS doors, peering outside into nothing.

Absolutely nothing. No starlight, no planets, no gas clouds. Nothing.

"No... No, no NO!" It can't be, that can't have happened!" He shouted, smacking his hands onto the control unit. He began frantically flipping levers as the TARDIS doors closed on their own. He smacked buttons and flipped switches until eventually he felt turbulance once again. He opened the TARDIS doors once more and saw that he was back in the atmosphere of a familiar planet.

"That can't be... No, it's... It's Earth... But it can't be, that's impossible...," The Doctor thought carefully, scratching his chin as he came ever closer to the ground. Suddenly realizing what was happening, he shut the doors and grabbed hold of the nearest handrail. He hurtled toward a foreign earth at hundreds of miles per hour, finding himself in a new and strange universe. He slammed into the back wall of the TARDIS as the impact with the ground set the entire ship into lock-up. THe controls all froze up, the glyphs stopped flashing, and the alarms stopped screaming. Smoke filled the control room as the Doctor slammed into thick alloy wires, electricity shooting through his body and stopping his right heart. He screamed in pain, the shock overwhelming. He crawled for the control unit to assess the damage, but couldn't go any more than a few feet. He felt energy building up inside him, his body beginning to go numb. His vision darkened, and death began to embrace him.

"Please... he begged to nobody in particular, "Please, I... I don't want to go yet... There... There.. There's still so mu.. so much I need to fix... I need to-" He was cut off as golden light flowed from out of his pores, pain engulfing his body. He felt strange, horrifying mutations take place. Hair sprouted from every inch of his body, and he became shorter. His face extended slightly, and his bones changed shape. The agonizing process ended, leaving the Doctor feeling better than ever. Still two heartbeats, and all of his organs were there. He stood to look in a mirror, when he notice the peculier way he was walking. He couldn't put his finger on it, but he knew that something was very wrong. He looked into the mirror on his TARDIS's control unit, and stared in shock. His jaw dropped.

"What in the bloody hell am I!?" He shouted, jumping back from the mirror. Suddenly, from outside, he heard a high pitched and giggling voice respond through the open TARDIS doors.

"You're a pony, silly! What are you doing in there?"

"Ah! Who are you? Where am I? Isn't this Earth? Better yet, do you have any English muffins? I have a very, very sudden craving for some odd reason," The Doctor babbled on in a confused state until he realized what the voice was coming from.

"Er... Are you, uhm... Are you a horse?" he sputtered, becoming more and more baffled by the second.

"Well... Actually, I'm a pony. I thought pretty much everypony was, except for the tall ones from Saddle Arabia. I've heard people call them horses," She said, slightly taken aback by the Doctor's seeming stupidity.

"Everypony? Saddle Arabia? That's brilliant! I should say that more often... Brilliant, now, do you know where I can find an English Muffin?" The Doctor continued to babble on about English muffins as the oblivious pony stood outside the TARDIS, waiting politely for him to finish.
