After the unicorn slept, Toothless went into Derpy's bedroom. Toothless crawled onto her bed and shake it violently, causing Derpy to wake up.
"Toothless, what going on? Do you have to wake me up at 2 am at night?" Derpy asked, confused at what is going on. Toothless eyes' pointed downwards and have a frown on his face, as if to say sorry.
Derpy smiled. "It's okay, I am just not used it. Is there any urgent matter that I have to deal with?" Toothless nodded. He grabbed some paper and a pen near the table and wrote down what had happened.
The changelings was taken away by the royal guards and was placed in an undisclosed facility. When Silver knew of this, she used me to fly to the location. Clover's forces was there to stage a rescue attempt too. While the royal guards was distracted in engaging clover's forces, Silver went into the facility and freed the prisoners. After freeing the prisoners, she went into the records section and took the document with her. Clover and her forces encountered her and she immediately left the place. The facility was latter destroyed by Clover's forces. Silver is currently sleeping in the bunker.
Toothless handed the paper to Derpy. after reading it thoroughly, Derpy's normal smile turned into a frown. Toothless saw it and went up to her. "Woroo?"
Derpy sighed. Derpy put on a cloak and went downstairs and into the underground bunker. Toothless followed her downstairs. As she entered, she saw a unicorn sleeping peacefully on her bed. She went up to her and kissed her on her cheek. "Your intentions are well, but you are just so hot-headed. Just like your father."
"Where is the document that she took?" Derpy asked. Toothless uses his mouth to pull a document that is underneath Silver's bed. Derpy took the document from Toothless's mouth and read the title. "Secret Unicorn project"
"Woowoo." Toothless commented. "Woroo." Derpy replied.
Derpy opened the document. Inside the document, there were details of how the secret unicorn was created and a range of operations it could take part in. There was also details on specific unicorn parts, like a longer and sharper horn from regular unicorns. The idea was to produce a equine that could do a multitude of tasks so there would be less manpower requirements. The project was eventually cancelled due to a change in high command. By the time the project was cancelled, one prototype was produced and is operational. The given name was Silver, due to the equine having a silver horn.
Derpy was involved in the project. But not in the way that a normal pony would expect. She was also a unicorn, and at the top of her head,there would have been a bright golden horn. These unicorns were very powerful, they have larger magical reserves as compared to an average unicorn. The amount of magical potential that each unicorn has is different and is represented by their horn colors. The main three colors are Gold, Silver and Bronze. Gold horns are usually reserved for royalty. This was why they were hunted down by military forces around Equestria and surrounding nations. Some secret unicorns would either be captured and drained of their magic, or commit suicide before capture. This lead to a rapid decline of the secret unicorn in Equestria. Most secret Unicorns flee the continent to the human world, where they set up a cloud city, called Acardia. Derpy had only discovered that she was one when she was under Clover's care and was involved in the project shortly after she became an officer of the Equestrian royal guard. No long after, the ponies found out about her secret and used her and a captured male unicorn to produce Silver. Even after the project was cancelled, several royal guard members continued to conduct extensive tests on Silver's capability. During a test near the border, gryphon raiders raided the place. A battle soon occurred. While it showcased the Silver's ability to fight, it also took the life of some pony dear to Derpy: her husband.
It was something that changed her life forever. After the battle, she adopted Silver and built an underground bunker, with Pinkie's assistance of course. Since both mares required items to be store/hidden underground, they worked together to build an extensive underground tunnel system. Pinkie's main rooms were more party-based , it consist of party supplies, party cannons and the documents of everypony's likes and dislikes. Derpy's main rooms were more defensively built, it consists of a underground bunker that could act as an air raid shelter if needed, an armory which stored muffin cannons and Toothless's tail variants and several historical documents. The historical documents was brought by her adopted Unicorn mother and was given to her to read it in her free time.
As these memories flowed back into Derpy, Toothless walked to her side and rubbed his head against Derpy's fur. Derpy responded patting Toothless's head. "Good Dragon."
"Maybe it's time to introduce them to her." Derpy said., thinking about whether to reveal it or not.
"Woroo?" Toothless asked.
"Yes. I am sure. I mean, it is what they need right now." Derpy explained. A smile stretched across Toothless's face.
"We shall do this tomorrow, after getting a good night's sleep." Derpy said, as they both head back upstairs and sunk their heads into their beds.
Next Morning
"Rise and Shine, my little muffin. It's time for school!" Derpy shouted.
"Five more minutes, mum."
Derpy entered the bunker, and paste a note on the table. Derpy proceed to remove a book from the shelves of a secret room and placed it on the table.
"Sparky and Thorax, wake up or you'll miss breakfast!" Derpy shouted from the ground floor.
A guardspony approached Derpy's house and knocked on the door three times. Derpy rushed to the door and open it. Once she saw the guardspony, she frowned.
"Commander, the Captain needs to speak to you."
Derpy groaned. She knew what was coming. "What is it this time?"
"One of our outpost has been attacked yesternight. The captain believed it was done with weapons far more advanced that we have seen. Since you are the artillery expert, the captain would like you to do an analysis of the damage done and do another task that will be given to you in private."
"If is a foreign item, why don't he consider asking Pinkie Pie? Why me?"
"I leave that to the captain to explain."
"Message received. I will be there as soon as I can."
The guardspony turned around, heading back to its original duties.
Dinky came running down the stairs. "Okay, Mum, I am ready for school." Derpy looked at her daughter, and forced a smile.
"That's great Dinks, come on let's get you to school." Derpy said, before carrying Dinky on her back.
Before leaving out the door, Derpy whispered "woroo, roowo" and took off.
Sparky and Thorax came down not soon after to have their breakfast. As they were eating their breakfast, Sparky could have sworn she saw a little fly carrying a golden coin fly out the main door. 'Probably my imagination' Sparky thought.
In the underground Bunker...
"Ahhh, what a nice rest." Silver said, while stretching her hooves. Silver noticed a note on the table and it reads,
Read the book with the changelings and their dragons while I am gone. I am sure you will find this story quite 'interesting'. Love, Derpy
The book that Derpy had placed on the table had no title. It only had a cover page with a large dinosaur-like creature in a house, with many smaller creatures around it. The creature was huge and it definitely towered over the ponies below. This creature looks kind of friendly though. It was smiling, though it did not conceal its horn-sharp teeth and had numerous spikes on her back. It also had a long tail, a horn on its head and wings on its back too.
"Wow. Thank you Princess, as if I need to learn more about other creatures. This better be a good story." Silver said sarcastically.
