Rainbow Dash had to admit, for all the hype Celestia had given this room, it...really wasn't anything special. As she walked around, all she saw was random junk scattered around everywhere. Vases were placed everywhere they could be without getting in anyone's way. Which was obviously very easy to do, considering how large this room was. Glass tables were spread out inside the room, and wooden furniture was apparently the dominant species on this strange new planet she had walked into.
And yet, as she looked up to the ceiling, her opinion of the room dropped even further. What use was all this space if it was used to hold nothing but junk?
She looked around some more, flying around the objects in the room and looking them over one by one. Then, as she saw the thing on the far right wall, she had had enough.
Rainbow Dash pouted. What had Celesia expected her to do in here? What were perfectly usable weapons doing in a room full of nothing but trash?
She left the room and made her case to the royal alicorn. Celestia simply smiled.
"Why don't you try it out?" She said.
What? How was she supposed to do that? What exactly was she supposed to try out?
"Go on. Pick a weapon and get breaking."
Breaking? What was she supposed to break? It was only when she looked back at the room that she understood what the princess had meant. She took note of the smile Princess Luna now wore. She had joined her sister in the journey to this room some time before, but apparently Rainbow Dash never noticed.
She reentered the room, grabbing a hammer from the weapon rack and moving towards a vase. She put it in her teeth and brought it down hard on the ceramic surface, smashing it to bits.
She still didn't understand it. She looked back to Celestia, who simply smiled wider.
She broke another vase, and another, and another, until, at long last she finally stopped. She didn't get why, but as she kept smashing these objects, her anger slowly faded away. She felt just fine now compared to how she had felt only moments before. It was as if these objects had some sort of magic spell placed on them to give some sort of calming effect. She asked Celestia.
"There is no magic involved in this process, Rainbow Dash. It is simply you releasing your pent up frustrations."
That's what this was about? Rainbow Dash smiled.
What followed after was nothing but the sound of breaking objects as she spent hours upon hours of time smashing things and tearing them apart.
She soon left the room, a wide smile on her face as she did so.
Luna sat on her haunches outside of the room, apparently waiting on her.
"Hi Princess Luna! Where's Princess Celestia."
"My dear sister has retired for the night. As it is my duty to raise the moon, I must remain awake. Did you enjoy the room, multicolored one?"
"It was alright. I think i'll come here again sometime."
Luna smiled, and with those words, watched silently as Rainbow Dash left the castle, doing so quietly as to not awaken the sleeping princess Celestia.
When she returned to her friends, Rarity was the one to voice the group's worry.
"Where have you been, Rainbow?! We were worried sick about you!"
"Just out."
"Oh, this is all because I said all those horrible things to you isn't it?"
"Don't worry about it Rarity. It's all water under the bridge now."
"Oh thank heavens! I was so worried you would hate me for what I said. But then, what were you doing, Rainbow Dash?"
"Oh nothing. Just....letting off some steam."
