"So why are we going to go back to the castle again?" Vinyl asked the Assassins.
"Oh Vinyl dear. We need some answers, that's all. You think that we will kill all the inhabitants in the castle. Of course no." Octavia replied.
"Well that suppose answers my question." Vinyl said.
"Ah Vinyl, don't get your nervousness have you. You will soon learn what your capable of." Rainbow Dash said.
"And what's that?"
"You will know soon." Scootaloo with a smirk. The four ponies finally got to the point wherein they are now in the Royal Canterlot Gardens undetected by the Royal Guards.
"I suppose you know this place, did you dear?" Octavia asked.
"Well yes. This is the place wherein we first met, without your names being known though." Vinyl replied.
"Exactly Vinyl. However, you should this place also contains a lot of secrets." Pinkie said. Vinyl didn't get why the Canterlot Gardens were special.
"Why is it special anyways?" Vinyl asked.
"It will be known soon. However, we must find it." Rainbow Dash said.
"Find what exactly?"
"Try to find something odd in this gardens. Your senses will come in handy." Scootaloo replied. The Assassins got to work, with Vinyl also doing the same, but it was odd for her working with Assassins, let alone her friend is also like them. She shrugged the feeling of doom with these Assassins and continued her search.
'Let see....Something odd. How am I suppose to see something odd here?' Vinyl thought in her head as she continued. However, her senses kicked in, and her eyes began zooming out as far away as it can.
'W...What the?! How did I see such things immediately?' Vinyl asked herself confusingly, but then her eyes come up with something. It was a bush, but it was attached to something. Her instincts told her just to go near the bush, and her hoof suddenly pulled it. Out of the blue, a large door opened up, with a stairwell leading towards the deep earth.
"Hey guys! I found something!" Vinyl shouted as the Assassins got to her location. When the Assassins got to her spot, they have their faces with satisfaction. They descended the stairs without any question, and when they got to the bottom part of the stairs, it was totally dark.
"Hey! Why is it so dark here?" Vinyl asked.
"Why ask? Your a unicorn right? Use your magic." Scootaloo said. Vinyl just facehoofed herself. She focused her magic and her horn began to glow, almost lighting the place up. In an instant, they could two pathways leading in opposite directions, one in the left and one in the right.
"This pathways seems odd. Why two of them?" Vinyl asked her Assassin companions.
"I don't know why they are hear Vinyl darling. Regardless, we need to split up." Octavia suggested.
"I agree. Okay here's the plan. Me and Octavia will go to the left, while Pinkie and Scootaloo will go to the right. You Vinyl will got to our searching party. Got that?" Rainbow Dash ordered her comrades, while asking Vinyl at the same time.
"I guess..." Vinyl said with some nervousness. And without any other sayings, the parties got to their work.
-Left Searching Party-
The Left Party got to the left corner of the underground mystery, wherein Vinyl was now getting extremely nervous.
'I don't know what we will encounter. Regardless, although I'm nervous, I need to get moving.' Vinyl thought as she and her Assassin companions kept moving. When they got to the end of this left corridor, the Assassins gave it a stoic expression.
"What's with the expression?" Vinyl asked.
"See it for yourself." Rainbow Dash replied. Vinyl stepped in forward, and what she saw was surprising for her, but not for the Assassins. In the room was lots and lots of books, and in the center was a cross with a sun on it's center.
"Just as I thought." Rainbow Dash said.
"Why? What's the matter?" Vinyl asked.
"This contains lots of evidence that our ruler, Princess Celestia, is a Templar herself. We are suspicious of her, but we shrugged it like it was just a theory. But now, it's now true." Rainbow Dash replied. Vinyl got stuck in her mind: How does Celestia becomes a power-hungry Templar? What was her deal with them, and what was her business?
"Why? Why does Celestia became a Templar in the first place?" Vinyl asked.
"That we do not know of Vinyl darling. Regardless, we must keep searching." Octavia replied.
-Right Searching Party-
Pinkie and Scootaloo is now walking in the right corner of the underground mystery. They are wondering what mysteries will await them as they approached the end of the tunnel. When they got there, however, was far more interesting.
'What the....'Scootaloo almost cursed as she and her mentor saw it. It was a very large library, and in the middle, was the Assassin's symbol, with Luna's cutie mark in it's center.
"How did Luna's cutie mark got their?" Scootaloo asked her mentor.
"I don't know my student. Regardless, we must search the entire place. I'm sure that the others in the opposite direction is also searching." Pinkie replied with a smile. And with that, the Assassins got to work, to search the entire place up for something deep is hidden beneath this underground complex.
