Sunset Shimmer flew through the portal rather quickly which resulted in her belly landing on the cold hard floor, and upon coming to, she shook her head and turned around to stare at her reflection. No longer was she a human,  but a pony... her true self which she abandoned long ago.She sighed 
as she looked around the familiar castle which had not changed at all despite it having been a long time.

"I can't believe i'm home," she said to herself ."
"Neither  do I." Sunset jumped as she saw the face of her mentor ... the one she betrayed... the one who took care of her as a filly... the one who gave her warmth like a mother would fas if she was her own child
when no one took her in after her parents abandoned her when she was young. 

"Princess Celiestia!" Sunset screamed with joy. A smile spread across her face as she ran towards the princess for a hug, and princess Celiestia wrapped a wing around her former student. The two just hugged 
and cried for awhile the Princess Celiestia stopped because she had something important to say. The warmth of her ex mentor slowly faded as Sunset stopped crying she looked up and saw the princess with a look she was excepting. Sunset gulped and bowed her head.

"I know I did wrong before but Princess Twilight showed me the true meaning of friendship, I am learning a lot from my new friends , but I know I deserve punishment for what I have done in the past." Sunset kept bowing as she waited for her punishment but as time slowly passed she glanced back up , and noticed she was ...smiling?  

"I know... Princess Twilight told me all about your adventures in the mirror world, and how you helped defeat the sirens as well as learning friendship in another world for the past few years; but now Sunset Shimmer I do believe you are here for another reason, You aren't punished in fact I was waiting for you to return someday and now you have." Princess Celiestia said chocking up a little. Sunset sighed with relief but then got serious. 

"I came here to get things back to the way they were. Rainbow Dash  has been acting weird like she's being controlled by something ... or someone. The sirens came back and  apologize then told us something 
rather interesting." Sunset pauses as she took a deep breath and then continued.

"The sirens said that their master was Starswirl the bearded but how is that possible if he was the one who banished them to the mirror world in the first place; not to mention he's the unicorn who practically wrote every spell and enchantments that pony was legendary!" 

Sunset said with frustration  in her voice.It was then the princess frowned.

"It is time every pony knows the truth about Starswirl the bearded it is true he was a genius but yet he was sinister. You're not the only one who has been sining."

Sunset Shimmer was shocked, at the princesses words what is she talking about?

"Do you mind waiting on the others while I go and make us some tea? This will take awhile to explain. I'm going to write to Twilight and tell her to bring the others.  We 
might have a new enemy in the near future and it could be Starswirled the bearded himself."
