Part I
Setting: Canterlot castle’s throne room, with Princesses Celestia and Luna facing Moonghost who has just entered the throne room through a portal, leading King Sombra and Queen Chrysalis, with Dr. Hooves in tow.
"Time isn’t an issue is it Celestia?" Moonghost said, “Although, I prefer night myself. I shall return at sunset."
Moonghost then turned, handed the folder to Dr. Hooves and then he, Sombra and Chrysalis all disappeared simultaneously, melting into shadows, then fading into nothing, leaving Dr. Hooves behind with the folder.
Dr. Hooves then took up the folder, walked over to Princesses Celestia and Luna, handed them the folder with a smile and said, “Well, I am going home to take a nap. I’ll be back at sunset. I don’t want to miss this.”
With that he pulled out some car keys, he pressed a button on the key fob. As soon as he had pressed the button on the fob, out of nowhere a dark blue telephone box appeared several paces in front of him. He then walked over to the telephone box, opened the door walked inside, and turning as the door closed said, “Well, see you at sunset.”
As the door on the telephone box closed and Dr. Hooves’ smile faded from sight, Celestia and Luna both exclaim in confusion, “What don’t you want to miss tonight?”
The door on the box closed tight and the telephone box disappeared in the same way it arrived, fading into nothingness.
As this happened, Luna turned to Celestia and said, “What in the world is going on?”
Celestia blinked looking at where the telephone box disappeared and then at Luna and said, “I don’t know, but I think we better read what’s in that folder.”

Part II
Setting: In a cave in the Everfree Forest Moonghost, Sombra and Chrysalis all appear, each from a small pool of shadow. They stay in the dark as they talk about what to do next.
“I think that went well” said Moonghost.
“That went well?! What exactly did we do?” said Chrysalis, “That was a waste of time!”
“We did what I said we would do, we addressed Celestia and Luna, and we set an appointment. When we return, expect them to have back up” said Moonghost.
“Expect them to have back up?! We are the ones that should have back up! Better yet, we should attack somewhere that will be weak because they have gathered everypony to be their back up” said Sombra.
“If you two are afraid to go to an appointment with these ponies, that you seem to consider as weaker than you,” said Moonghost with a smirk, “you do not have to come. I am quite capable of doing this on my own.”
Chrysalis stuttered, “W..we..wee didn’t mean that we were afraid.”
“Yeah, we are certainly able to go, but we do not know why or for what purpose we are doing this” said Sombra.
Moonghost, looked at them each in the dark of the cave, with an expression of irritation and patience, as though he were dealing with well-intentioned but uninformed children. He sighed and said, as he drew his hoof across his face in exasperation, “I will tell you what it is all about after this meeting. However, for now, I do not want you to come. Please make your way to the former lair of the Arimaspi. Unless I am mistaken it is abandoned. I will meet you there in a day or two. I expect this meeting could take quite some time.”
