Deep within the woods the small town of Gravity falls, stood a cove untouched by man. Outside the entrance stood a white hair child with green eyes. The child took out an old book, with a symbol on it, out looked in it before descending into the cave. The cave was pitch black, the only light available was from the other worldly glow emitting from the child's hand scatter throughout the cave were technology far more advance far beyond any intelligence species imagination, all warped and stretched and some were even split in half.

As the child was progressing deeper into the cave, the child couldn't help but stare at the warped technology in both awe and curiosity. When the child entered the final chamber of the cave, the child noticed how the chamber was shaped like the inside of a sphere and that there were four metal bridges intersecting at the center of the chamber and connects at the four corners of the chamber. The child also noticed that where the bridges intersect, stood a cylinder shaped machine with same symbol the book the child has. The child then flew straight toward the machine. When the child reached the machine the child noticed that the machine was glowing lightly and there was only one switch connected to the device. The child being curious, flipped the switch, as soon as the child did, the machine then glowed incredibly bright and hummed to life. A voice is then heard. The child could not make out most of the words being said, but by what the child could hear, the child can conclude that whatever the machine is, it is able to combine different worlds together. The next thing the child knew, the chamber was flooded by insanely bright light. The light then expanded from the chamber to the outside of the cave entranced, then covered the entire universe.

When the light faded, the child's eyes open and laid outside of the cave the child was in. The child also noticed that the environment was slightly differently than what the child remembered. Certain tree's leaves were a different color from before, boulders that the child didn't see were now everywhere in the woods, even the cave the child was in disappeared, as if it was never there.

The child then heard the sound of shattering stone coming from behind one of then began approaching the boulder turning invisible in the process, in case the source of the noise was an attacker. When the child was near the boulder, the child then heard groaning. Cautiously, the child looked around the boulder, only to see a black dragon wearing dark grey armor, laying his back against the boulder and was holding his hand to his head. The still invisible child look at the dragon, but accidently kicked a piece of stone the child failed to notice. The noise caught the attention of dragon the black dragon opened his eye lids, revealing blood red iris, and looked in the general direction the disturbance came from, and where the still invisible child stood. The child did not move a single muscle, worried that doing so would reveal the child's location to the dragon. The dragon stood up on it's two hind leg, and began standing in a fighting position, still looking in the general area the invisible child stood. After a short while the dragon then closed it's eyes' the dragon poster then relaxed and began standing straight. The dragon then open it's eyes, and to the child surprise, the dragon was looking directly at the child. "Don't be scared, I'm not going to hurt you. You can stop hiding." Said the dragon with both a caring and gentle tone. At first, the child did not believe the dragon, but after a moment, the child ceased being invisible. The dragon's first expression when he saw the child was mild shock. The child raised an eyebrow and said" What? You knew I was invisible." "Sorry, but…what are you?" the dragon asked. "I'm a ghost, hello." The child state as if it were the most obvious thing in the world. The dragon deadpanned at the child and said "ok, but of what, or in your case what is your living half specie?" The child was shock. 'how does he know I'm only half-ghost!' The child thought. The child was then more suspicious about the black dragon, but then realized he doesn't know what the child's human-half is, which made the child confuse. "My other half is human. But how do you know I'm only half-ghost?" the child asked. "I saw that about half your own personal energy was ectoplasm." The child just looked at the dragon with a bored looked. "I know that look, that's the same look people give me whenever I say something like that to them. So you before you ask, I have this…unique ability to…see a person's energy, but the only known way for someone with that type of ability, is to not look their own eyes." The dragon explained. "Ok…but why didn't you attacked me if you knew I here?" asked the child. "Well said ability allows the user to be able to see the basic nature of people, you know to see if their good or evil. Your energy showed me that you are not a malevolent child. So there no reason why I should attack you." Said the dragon. The child was amazed by the ability the dragon process, and then started to trust said dragon. "Um…I hope you don't mind me asking you this, but what's your name?" the child asked. "Oh I don't mind you asking me that, my name is Brad, Brad Saber, but people named me Darkwing. Don't let the name villagers call me make you jump to conclusion, I really am nice person." The Drag…I mean…Brad said. "That name, no offence I not calling you a liar, sounds more like a human's name than a dragon's." the child pointed out. "Really? Huh. Small universe." "Anyway, my name is Dani Phantom." The chi…I mean…Dani said. (N/A ok one is an accident, two is just silly)"I presume with I?" Brad asked but more in the form of a comment than a question. "hehe, yeah with an I. You know you are the first person I did not have to explain that to" Dani said. "Hey Dani, you know where we are?" Brad asked. "I think we're near the town of gravity falls," Dani answered. Brad his eye brow (not that he has hair) not really sure what gravity falls is. "but the land doesn't look the same as it did before, so I'm not really sure." Dani explained. "Well, only one way to find out." Brad said. "Can you fly Dani?" Brad asked. Dani only smirked and asked "Can you keep up?" with that she shot herself into the sky. Brad smirked, then opened up his wings, and like Dani, shot himself into air, instantly catching up to Dani. "Can you?" Brad asked as he was passing by the ghost-girl, then he began flying circles around Dani, making her dizzy. When the dragon stopped, Dani looked a bit green. Brad then began to laugh. Dani then glared daggers at Brad, then she smirked. Charging her ice beams that she learned how to control while on her travels. She then blasted her ice beam at Brad's mouth, freezing it. Dani then began to laugh hard, as Brad use his fire to melt the ice from his mouth. After he finish melting the ice from his mouth, he heard Dani gasped. He looked her to see that her face was full of fear. "Dani, what wrong?!" Brad asked. Dani simply pointed behind the Dragon. Brad looked behind himself, only to a meteor coming straight at them. "Ah, crud" Brad said.

Well that chapter one of this story. The next chapter is going introduce both Dani and Brad to the mystery twins of gravity falls and a two tailed fox, and will also introduce the protagonist. Again the only characters that belongs to me are my OCs all the other belong to their respected oweners
