Twilight was confused by the stallion that had just disappeared in a blue box and even more so that he had given her what appeared to be an invitation with a seal she didn't recognize. "Spike take a letter" she said, "Dear Princess Celestia, I have just had an encounter with a weird pony who gave me an invitation to something called a 'millenniual immortality conference'. I am even more perplexed by the fact that Spike was also given one. I am suspicious of this considering that it is supposed to take place at the third castle of the royal pony sisters. Considering you're living in your second castle I am inclined to believe that this is a trap of some kind.

She looked out a window, "you got that Spike?"

"Yup" the dragon responded and rolled up the parchment he'd be writing on and blew fire onto it. They waited a few moments for a reply. When it came back Spike read it aloud for Twilight and her friends to hear.

Dear Princess Twilight Sparkle,

First let me assure you that the conference isn't a trap and I encourage you to come. The strange pony you met is my good friend, the Doctor. As per why Spike was given one I do not know, the Doctor knows many things and refuses to tell them to most ponies.

Sincerely,

Princess Celestia

"Sooo..." Rainbow Dash started, "it's for real."

"The invitations allow us to take a plus one" Spike pointed out.

"So who you going to take?" Rarity asked.

"I don't know." Twilight answered.

"I do!" Came a familiar voice, and in a flash Discord appeared, "now my dear Fluttershy, I honestly can't think of a better pony to bring with me to the conference." He said picking her up.

"You were invited to this thing to?!" Apple Jack asked with a shocked look.

"Of course I was, it is a conference for immortals after all." He said, "now Fluttershy I'll pick you up at eleven a.m. the day after nightmare night, don't worry about getting dressed it's nonformal, like always. Now I must be off, I need to prepare myself." He said then opened a door that had not been there before and walked through it.

There was an explosion behind him, "get to the T.A.R.D.I.S.!" He shouted as he ran for the blue box grabbing his companions hoof. He pushed open the door and yanked her in then slammed the door shut as the explosion engulfed the T.A.R.D.I.S. "That wasn't so bad" he remarked.

"I was almost killed!" She shouted at him.

"Ah yes, well, it could be worse, no pony died at least. Only the automated crew." He retorted with a smile.

She gave him a look of annoyance, "you didn't have to blow up the ship though."

"Of course I did they had grown sentient and ponies aren't supposed to figure that little bit of tech out for at least four hundred years. Just imagine if they had figured it it out early, the consequences could be disastrous."

"Just get us back to Equestria so I can see my kids." She said walking away from him.

"As you..." He began but was interrupted by a alarm sound coming from the consul he rushed over to it, and his companion's eyes went wide in horror.

"What is it? Are we under attack?" she asked hunkering down.

"It's worse." He said grimly, "it's time for the conference." He said as he pulled up a list on the screen. "Ok this one happens at the third castle of the pony sister. Derpy prepare to meet some of the most important beings in your timeline."

"But I thought that I already had, what with the Beast, Rassolon, Chronos, and..."

He interrupted "No those are beings you met with me, I'm talking about beings that exist at the same time you do."

"But I already met the Princesses"

"True, but that was several years after this event" He said as he imputed the coordinates into the consul.

Celestia had ordered for a large round table to be made for the event when Shining Armor entered the room, "Princess, Cadence sent me a message saying that there was a odd pony that gave her an invitation to something called a 'millenniual immortality conference' and she asked me to ask you about it, with me being in town for the Equestrian Defense Summit."

"Tell her that the pony was a friend of mine and the conference is in fact going to happen here at the castle, and I encourage her to come."

Shining Armor smiled and saluted then dismissed himself.

Author's Note

Please don't get mad at this "filler" chapter, I only wanted to give some reactions to the Doctor's odd appearance.
