Okay the six ponies were shocked at what they saw because,they told Flutter shy what they seen.
Pinky pie," I walked pass that
Rarity," Thank GOD you didn't see it
Rainbow dash," We would have been caught for sure."
That's when the six ponies started getting nauseated and five of them passed out except rarity
Rarity,"What are you?!?"
As they were getting drug back to the castle the long skinny thing and the guards were talking but not with there heads but with there minds. since the tall thing well (it) didn't have a mouth.
The six ponies were laying on a long flat aluminum table. As they awoke the creature was talking to them with his mind
creature,"My name is, I am the Slenderman, world legend."
Rainbow,"What do you want from us?"
Slenderman,"Your lives our your services.
That's when Rainbow Dash noticed a symbol they saw in the woods. She realized what was going on The Slenderman was controlling Cellestia's guards and making them do what he commands.
Slenderman,"That's right."
Rainbow dash,"what,how did- oh yeah."
Rarity," Please don't hurt us."
Flutter shy,"Meep."
The guards walked up to torture the ponies when they let them out to bring them somewhere else but Rainbow dash kicked the guard. Flutter shy went to hide under the table while the other ponies tried to fight the guards. Twilight with her computer skills and smarts knocked 3 of them out by a plan she hatched in her head while Rainbow dash and the others killed the others with brute force.
When they were done the Slenderman was gone and they were confused why this slenderman was doing this and why he was trying to kill us or make him our servant.
Rainbow dash," What the hell has been going on!"
Flutter shy whimpering,"I'm sooo scared!"
Rarity,''We should tell the others in the town!''
There faces went blank and they all just stared at each other and dashed out the door like the rest of them to the town of Equestria and there that creature was giving them that symbol and then they bow down pledging their allegiance. once they looked at the six ponies they charged at them.
