The next day, the mane six and Nathan were helping Twilight bring in some of her recovered stuff from the ruins of Golden Oaks Library and new equipment into the new castle. Fluttershy and Applejack pushed a large crate as Nathan opened another with a strange looking tool.

Just then a tall thin stallion with a grey coat and black mane walked in with a cart full of books. "Greetings Princess, where do you want these books from Princess Celestia?"

"In the library."

"Even this one that's glowin and vibrating?" Just then Nathan coughed.

Twilight looked to the top of the pile to see the book in question, she brought it down with her magic and the stallion walked off to put the books in the castle library.

Twilight opened the book and started to read as the others gathered around her, Nathan kneeling down to hear what they were saying clearer.

"What is it Twilight?" Asked Fluttershy.

"It looks like a message to Princess Celestia from my friends at Canterlot High."

"How is that even possible?" Asked Rarity.

Phone Book... Thought Nathan as he returned to carrying more crates into the castle.

"I have no idea but, it sounds like they need my help."

Here we go...

After a brief explanation as to Sunset Shimmers message, Twilight began to tell them all about the sirens as Nathan organised some of the bookshelves. "The sirens were three beautiful but dangerous creatures, who had the power to charm ponies with their magic. But to maintain this ability, they had to feed of the negativity and distrust of others. The more of this negative energy they consumed the stronger their voices became, and the farther they could spread their dark magic."

"I don't think I like this story very much..."

"If the sirens had their way, they could have divided and conquered Equestria. But a certain Starswirl the Bearded wasn't having it. Rumour has it, that with the help of a metal giant, he was able to banish them to another world, where he believed their magic power would be lost." They all looked to Nathan who just whistled as he stacked some books. "You fought the sirens alongside Starswirl?"

"Hmm?" Nathan turned his head to look at them disinterested. "Oh right that. Yeah, I knew Starswirl, pretty cool guy actually. The sirens weren't much of a challenge since their magic wasn't combat based." Twilight just looked at him with disbelief. "What?"

"You're acting like this isn't a big deal!"

"It really isn't, I doubt the sirens would risk returning to Equestria as long as Phoenix and I are here, and if they are staying in the other world then you can just build some device that opens the portal early and go sort things out." She just looked at him with a blank expression.

"You put that rather bluntly...but you are right, I do have the necessary equipment to build something like that." The group watched as bits and pieces of machinery floated over to Twilight and she began to, as Rainbow had put it, 'speak egghead.'

After that was done, Twilight placed the magic book in the machine and the portal activated. "Alright, Spike, let's go." The girls looked expectedly at Twilight. "No girls, everyone would be suspicious as to why there was two of each of you walking around, it would attract too much attention." The girls frowned and then looked towards Nathan.

"What?"

"You can still go with Twilight, you've faced the sirens before and you aren't from this world." Rarity stated.

"How exactly am I going to fit into the portal?" He gestured to his height. "I'm at my smallest size right now."

"I can temporarily shrink you down to fit." Stated Twilight proudly,

"Fine, it would be fun to mess with the sirens again."

Twilight nodded and her horn glowed, sending a purple aura over the ranger. He gradually shrank down to only slightly taller than the ponies. Twilight walked through the portal and was followed by Spike. Nathan took a look at his arm cannon and sighed. "I better not end up as some kinda toy robot." With that he stepped through the portal.

The human five and Sunset Shimmer sat around the statue awaiting Twilights return. Just the she came tumbling out of the portal.

"Twilight!"

"I'm back..." Sunset reached to help her up but she hesitated, she eventually accepted the help. "...but I have some bad news about those new girls." The group frowned. "Although, I brought a little help this time. Someone who fought the sirens in the past." They all looked towards the portal and someone else came out of it. He didn't tumble but slid across the ground on his knees and hands.

He got up and dusted himself off. He was a tall boy with an above average build, white skin and spiky purple hair. He wore a white coat that split into two points at the bottom, purple jeans and white boots. "Ah, feels good to be a human again." Nathan wriggled his left fingers a bit. "Been awhile since I had this arm, that's gonna take some getting used to."

"Nathan?" He turned to see Twilight looking him over.

"See something you like?" He asked teasingly. She blushed and tried to form words but ended up stuttering. "Relax, I was just teasing."

"Twilight...who is this...beautiful man?" Asked Rarity flustered. Nathan decided to play about with this. He took hold of Raritys hand and kissed it.

"My name is Nathan Phoenix, second in command of the Phoenix military group at your service malady." Rarity fanned herself with her free hand. Rainbow and Applejack struggled to suppress their laughter, Pinkie just raised an eyebrow and Fluttershy cowered at the new arrival.

"That's enough Nathan, stop playing with the poor girls feelings." Nathan groaned and let go of Raritys hand.

"You're no fun Twi."

"Nathan, is that you?" He turned a little to see Sunset looking at him with wide eyes.

"Well, if it isn't little Sunny. I trust you are no longer like the selfish brat I used to know?" Twilight just looked at them confused.

"Yes...thanks to Twilight I was able to turn over a new leaf." The two hugged and separated. "So this is what you look like as a human, I'll admit that I'm impressed."

"And like that we're done." Nathan pushed Sunset off and walked beside Twilight.
