Where am I? Who am I?

John and Spike left Canterlot. They arrived to the forbidden place of Equestria. It was near on the Ever Free Forest. There were some figures about old cultures. Nothing special. It was dark and cold.

"Here we are John." Spike said.

"What is this place?" John asked.

"The place where the ghost talks." Spike answered.

They moved in the small cave. There were some old bookshelves and in the middle of the room was a box which looks like a ... computer? Suddenly something strange happened.

"Hello and welcome to VOX-System. How can I help you sir?" asked a man.

Spike moved back. He was scared.

"It´s ok Spike, it´s ok I know what he is." John answered.

"What are you?" Spike asked. "You are the "ghost" right?"

"I am the 4th generation of holographic artificially intelligent system. How can I help you sir." said the system again.

"Photons right?" John said.

"Or rather what remained of it!" said the ghost.

"Do you know what happened here." John asked.

"No I haven't got longer access on my databank but what I know is that ponies rule the world now. A very clever species. said the Ghost.

"Yea ok but what happened to the mankind?" John asked him again. The ghosts looked at him.

"Excuse me Sir but these information's get lost." said the ghost and went his sight to Spike.

"Look at him." the VOX-System showed to Spike.

"Do you know how it is to remember about everything? I can remember a 10 years old girl who asked me about rabbits for 16.000 years ago." said the system and looked to Spike again.

"See they have no knowledge about the past no idea what happened ... the lucky." the system said.

"I have nightmares about my past. I ... I seen a dark pony who follow me on my dreams and try to..." John got abort.

"I know." the ghost said.

"But how could you know all about that if you can´t leave this place?" asked John the VOX-System.

"Now for a few hundred years a Pegasus pony come every day to me and told me everything about his life and their kind. We spent years together, just talking, he had the same nightmares about his past. The conversation is incomplete but I remember he killed themselves." said the system.

"You have spoken with a pony. Can you help us to find that pony, so we may find Rainbow Dash too." John said.

"I remember the pony told something about a cave in the "Ever Free Forest" its on the east. But be careful, the Ever Free Forest is the most dangerous place in whole Equestria."

"But I have to find her!" said John and got abort again.

"But what the truth is so horrible and hunt your dreams all the time?" asked the ghost.

"I am used to this." enclosed John.

"Can you describe the way to the pony?" John asked

"I haven't to. Follow the voice in your head." said the system and powered down.

"I still haven't got an answer what happened but maybe we know where Rainbow Dash is. LETS GO SPIKE." John said.

"I come with you my friend." Spike said and they left the cave.
