Who is Dusk Chaser?

A few months after the marriage of Rose Heart and Night Frisk, King Moonlight and Queen Sunshine gave birth to a young alicorn filly. She had a white coat and a pink cotton candy-like mane and tail, which flowed with the wind. They named the young filly Princess Celestia, named after her parents, with them controlling celestial bodies. The whole kingdom was overjoyed for their new princess.

The headlines that day were: "A NEW PRINCESS WAS BORN! EARTH, PEGASUS, UNICORN? NO SHE'S AN ALICORN!"

Rose Heart helped take care of Princess Celestia, cleaning her, feeding her, and generally helping out. Night Frisk guarded the room, being the head of the Night Royal guards, he added extra security in the palace by up to a thousand more guards in both day and night shifts. There were now millions of guards on guard that even a speck of dust couldn't make it into the palace.

After a year or so, the king and queen were told that they would have another child. Everyone in the kingdom was overjoyed by the news they received. However, this was not the only news the king and queen received, Night Frisk and Rose Heart were to have a child as well. The couple were so happy that they were finally going to have a child. They congratulated each other on the happy news.

The headlines read: "KING AND QUEEN ARE HAVING ANOTHER CHILD!' and on some other part of the paper: "King and Queen's Best Friend are Having a Child."

After a few months, the two couples gave birth AT THE SAME TIME. Born to King Moonlight and Queen Sunshine was another alicorn filly. She had a light navy blue coat and a sky blue mane and tail. This filly's mane covered one side of her face, enhancing her cuteness. They named this cute little filly Luna, named after her father, King Moonlight.

The headlines that day were: "ANOTHER ALICORN PRINCESS IS IN OUR KINGDOM!"

Luna was smaller than a regular newborn filly. The doctors said that this may sometimes happens. The doctors also said to make sure that Luna will always be taken care of. They said that her size will not affect her health but may leave her weaker than a normal filly. They also mentioned that she could make up for her small size with her enhanced abilities. They said that if a pony's size was smaller at birth, their magic gets compressed into the small space. This makes ponies' magic stronger and harder to control (Think of it like a bottle full of Coke, If you add a Mentos to it, the pressure builds up and if the bottle cannot contain it, it bursts, however, if the bottle is half full, and you add a Mentos to it, it won't burst since there is extra space for the pressure).

After a few moments later another foal was born into Equestria. Rose Heart and Night Frisk's child was born.

Born of Rose Heart and Night Frisk was a colt. His coat was a spotted navy blue with spots of darker blue. His mane was three different shades of blue, and his tail had blue, purple, and green shades. They named him after the newborn princess, since he was similarly colored, and since she was so adorable. They named him Dusk Chaser. They wanted Dusk Chaser to protect the royal princess sisters, especially Luna, since they were born at the same time. They wanted him to become a royal guard just like his father. They wanted him to be the best royal guard ever.

But there was something different about this colt. He was a pony with bat wings. This was shocking since no one knew any bat ponies. The doctors'research showed that in every 1,000,000,000,000 (trillion) pegasi, one of them may be a bat pony. Bat ponies were a rare specie of pony. They are rarely heard about. But that was not the only thing different about this colt, unfortunately, one of his wings was smaller than the other. The doctor said that this may cause difficulty or pain in flying.

Suddenly, for no reason, Princess Luna started to cry. No one knew how to stop her crying. No matter what anypony did, the newborn princess wouldn't stop crying. Suddenly, Dusk tried his best to fly over to Luna despite his wing problem. since being a newborn colt means not being used to flying, this was a little difficult to do. As soon as he made his way to Princess Luna, he laid down beside the newborn princess and stretched his wing over her to comfort and protect her. Feeling safer, Princess Luna finally stopped crying. This made everypony in the room smile.

There was a law that if a pony does a deed that would protect the royal family, that pony may be granted membership to the royal guards. This may include saving somepony, accepting a task, or anything deemed worthy by anyone from the royal family. What Dusk did was so touching, they considered turning him into a royal guard. They realized that Dusk did protect Luna. The way Dusk flew, even though it was really terrible flying, over to Luna as quickly as he heard her cry, and the way he protected her with his wing was the best deed they ever saw. Both King Moonlight and Queen Sunshine agreed that Dusk would become a royal guard just like his father as soon as he is of age.

Rose Heart and Night Frisk were so proud of their newborn son. They took care of him just as they took care of Princess Celestia and Princess Luna. Since King Moonlight and Queen Sunshine were always busy with royal duties, Rose Heart took care of the three foals every day. She would always feed them, wash them and play with them. The three foals were inseparable, they would eat, sleep, wash, and play together all the time.  Night Frisk made sure to guard them extra carefully. He added even more guards to the palace. Now there were trillions of guards around the palace.
