Hello there everybody and thank you for reading. I shall tell you one thing and that is, that this is the first Unfinished Swan crossover fanfiction. After the trouble of asking to put Unfinished Swan on here, I've decided that now is a good time to write it. So sit back and enjoy.

Celestia's Castle

Celestia sat on her throne waiting for Princess Twilight to come. She kept on waiting until her sister broke the silence.

"Sister are you sure that she should be doing this." Princess Luna said.

"She's proven to me that she is ready. Besides she has completely one of Star Swirl the Bearded's spells." Princess Celestia said trying to calm Princess Luna down.

"But that was just a spell this is much more different and dangerous. But if you do want her to do this, then shouldn't we at least give her some backup."

Princess Celestia thought about it and came to a conclusion. "If, and only if we see that she needs it."

A royal guard came in through the door.

"Please excuse my intrusion your majesty."

"Yes, what is it?" Princess Celestia asked.

"The princess has arrived." The royal guard said.

"Good, bring her in please." Princess Celestia said.

"Yes your majesty." After that the royal guard left to get Twilight.

Princess Celestia looked over at Princess Luna. "You seem nervous."

"I'm just concerned about her doing this."

"Being concerned about another pony is important. It is to have faith in her is what you should also do."

"I do have faith in her, I'm glad that she is doing this for us. It's just that, I hope that she'll be alright."

"Do not worry little sister, she will be alright."

After their discussion Twilight came in through the door.

"I got your urgent message. What is it this time?" Twilight asked.

Princess Celestia wrapped her wing around Twilight motioning her to follow her. "Follow us the Star Swirl the Bearded wing and I'll explain the rest when we get there."

After that the three princesses left to the Star Swirl the Bearded wing.

Star Swirl the Bearded wing

"I know how you helped me with that unfinished spell from Star Swirl the Bearded and because of that you've proven to me that you were ready to take on the responsibility of a princess." Princess Celestia explained.

"What does that have to do with my new assignment?" Twilight asked.

"Star Swirl the Bearded was well known for many powerful magic's. But there are some things that he wanted to finish but he couldn't, like that spell for instance. But to top it all off, the one thing he really regrets not finishing…" Princess Celestia used a levitation spell on a book to bring it down to them. "…is this."

Twilight looked at it and then she got confused. "What's so unfinished about this? It looks fine."

"When you look at the pages it does look fine, it is what's deep inside the pages of the book that is incomplete." Princess Celestia said hoping that, that would answer her question.

"I still don't get, but if I do see something then I could just write it in." Twilight said.

"I'm afraid it isn't that simple Twilight."

"What do you mean?"

"She means that this book won't be finished just like that. The book itself is made of magic and the only way to finish this book is to go inside the book and finish it there." Princess Luna explained.

"Wait…I have to go inside the book. Isn't that dangerous?" Twilight said very worriedly.

"Not unless you're properly prepared. Now I will use my magic to send you into the book." Celestia used her magic to grab something. "You will need to take this with you."

"What is it?" Twilight asked.

"That is the key to completing your mission." Princess Celestia said.

Twilight tried to use the object Celestia gave her but nothing happened. "Nothing happened."

"I'm afraid it only works when you're inside the book and trust you'll know when you need to use it." Princess Luna said.

"One last thing Twilight, this book is very powerful. While you're there the nature in that book will be very hostile. So I urge you to use caution during you assignment." Princess Celestia said.

"Why, what's going to happen?" Twilight asked.

"You'll know when you see. We have faith in you Twilight." After that Princess Celestia used her magic on Twilight to send her inside the magic book.
