Author's Note: Hey there everyone. This is my first ever fanfic, so I hope y'all like it.

Disclaimer: I do not own TMNT or most of the story lines. The only I own is my OC Terentia.

Warning: As the story goes on, there will be blood, so a heads-up for readers who hate that kind of stuff.

Prologue

The nights were getting longer. Pearl white snow fluttered down to the streets of New York. The sky turned gray. Winter was on it's way.

A gray rat the size of human, strolled down the sewer tunnels carrying four slightly wore-down blankets. The blankets were for his sons. Because the weather topside was getting colder, his sons would need them. He didn't like leaving his sons at home, especially since they were all only four years olds. He never knew what they would do without him there. But he did trust them enough to at least stay at home.

He turned the corner and a few steps later, he was home. The rat walked through the doorway, and saw four, children sized turtles gathered something on the floor. They looked scared. This worried the rat.

What have my sons done now? He thought.

One of the turtles, his skin was the color of an olive, looked up and called to the rat, "Master Splinter! Come quick!" Master Splinter dropped the blankets and ran over to the turtles. He looked down into their circle and, in the very middle, was something round and green, like the color of a leaf in summer, and it was shaking.

"It's Raph's fault!" blurted out a jade green turtle, standing up and pointing at the emerald green turtle next to him. "He found the ball and said we should play with it." The other turtles each let out a yelp and crawled further away. Splinter and his son looked down and saw something sticking out of the ball. Something pale green, like a green pearl. Another yelp was heard and Splinter felt something tugging his robe. His hiding son let out a quiet whimper. Like a fast growing plant, something else popped out. Soon enough, the entire thing crumbled away. From there the orb stood, a pale green turtle, the size of an average human baby, laid there. With a thin layer of strawberry-blonde hair, three fingers and two toes. It was a baby turtle girl.

The four other turtles were confused. They weren't frightened anymore, but they had no idea what happened. The three turtles crawled forward to the crying baby. The last one moved away from his father and joined his brothers. Splinter smiled. He knew this day would come.

One of the turtles, a leaf green color, slowly moved his hand towards the baby. The baby suddenly grabbed his finger with both hands, without even opening her eyes. This surprised him, but that moment lasted a few seconds for two reasons. One; the shock turned into happiness. And two; Splinter picked up the baby in one of the blankets he brought. Also, for the first time, she stopped crying and opened her eyes as soon as she noticed she grabbed something. Deep violet eyes stared at the young turtle, turning his heart to mush.

Splinter cradled the small baby turtle, who looked straight at into Splinter's black eyes.

"Masta Splinta, what just happened?" the emerald green turtle asked.

Splinter sighed, "I guess you all should know. When I found you as infants, you were not alone. Along with you, was a small turtle egg. That too was mutated, turning it's shell green and slowly growing in size over the years. Once I found this place, I kept the egg in, what I then thought was a safe place. I was not sure if it ever would hatch. Until now."

The four turtles became silent for a good minute.

"I was wondering why it moved around," said the olive green turtle.

"Wow," the jade green turtle said. "Now we have a little sister?" Splinter nodded.

"Wow!" All four turtles exclaimed.

"I am glad," Splinter said. "But now it is time for bed." The four turtles whined. They wanted to stay awake with their new sister. Splinter's sons reluctantly stood up and headed to their bedroom. Splinter followed them, tucked them in, said good night to them, turned off the light and left the room with the newborn.

Suddenly, the baby rested her head against her father's chest. Splinter looked down and saw that his daughter was falling asleep. If he was prepared ahead of time, he probably would have set up a crib or something. Then, he found a laundry basket filled with more blankets and sheets. It would do for now. He walked across the room, placed his sleeping baby girl inside, and walked away.

Before he turned off and headed to his room for some sleep, he turned around, and whispered, "Good night, my daughter."

Author's Notes: And that wraps up the the prologue. I know my OC's name isn't Italian. For those who don't know, Terentia is a Latin name. But Latin did originally come from Rome, which is the capitol of Italy, so it kinda counts. Plus, I like the name and I don't really know any female Italian Renanssice names, other than Mona Lisa(but that was used in the 80's series), and Andrea (but other writers have used that name in their fanfics). So yeah...Oh, if you didn't catch on, the olive green turtle was Donnie, the jade green one was Mikey, and the leaf green was Leo. You probably knew which one was Raph.

For though readers who have been here since the beginning, you'll see that I made a lot of edits. You see, I'm doing my editing as I write and make changes if I have to. I know it sounds lazy, but that's how I write.

Well, I hope you enjoyed the prologue. I'm planning on writing the whole 2003 series, along with Turtles Forever, a sequel to it, and maybe even an epilogue series. That's all for now.

P.S. I know this chapter was short, but future chapters will be longer.
