Author's Notes: Scooby Doo and all related characters and trademarks are copyright 2010 Hanna-Barbera Productions/Warner Brothers/Cartoon Network. I am not making any money writing this story, I am merely a fan. This story is based on the Hanna Barbera/Warner Brothers produced movie "Scooby-Doo and The Goblin King". This story will have similar dialogue, similar plot lines, and most of the same characters from the movie; this will also include spoilers, if you have not seen the movie. Also, thanks to kitsuneofthenight from Deviant Art for the idea of the sibling characters, basically he came up with the idea for them and I named them and decided to make them a warlock and witch.
Chapter 1
Scooby Doo and the rest of Mystery Inc. are involved in yet another hair raising experience, each member of the great detective agency screams in terror at the ghosts, monsters, werewolves and other supernatural creatures that they are seeing; Shaggy and Scooby would normally be scared stiff at all of this except for the fact that all of the ghosts and creatures in this case are made of cloth, phosphorus paint, mechanical items, holograms and other things that would make it seem like the beings were real.
This time Scooby Doo and friends are not in the midst of solving a terrifying supernatural mystery, they are actually riding a roller coaster at their hometown's annual Halloween Carnival; the great roller coaster clatters along the metal tracks until stopping at the end of its route, after the coaster came to a full stop Scooby and company exited the coaster ride and walked back into the main carnival area.
"Boy, what a wild ride!" Daphne said, although somewhat out of breath.
"I'll say, I'm still trying to catch my breath from screaming so much and make sure I'm still in one piece" Fred replied, albeit in the same way as Daphne.
"Jinkies I can sure agree to that, what about you Shaggy and Scooby?" Velma asked.
"L-like m-my teeth are still chattering from all those ghosts," Shaggy said with his hair still standing on end.
"Reah, ry rur's randing ron rend roo" Scooby added.
"Come on you guys it's Halloween" Daphne remarked.
"Yeah you two where's your Halloween spirit?" Fred asked.
"I think it's home where Scooby and I should be, besides you guys do know what happens on Halloween night don't you" Shaggy said, still quite jittery.
"What?" Fred, Daphne and Velma asked in unison.
"Halloween night is supposed to be when Monsters, Vampires, Werewolves, Witches, Ghosts and all sorts of creepy creatures come out to scare people like us" Shaggy replied with a gulp.
"Rand rogs roo" Scooby added.
"Like yeah and dogs too" Shaggy commented.
"Aw, come on you two; you don't really believe in all that stuff do you?" Velma asked.
"Of course we do, besides on Halloween there's a greater chance of all that creepy stuff coming true" Shaggy commented.
"Ruh-huh" Scooby agreed.
"Don't worry you two, all the ghosts and monsters you see are fake; on Halloween everybody's dressed in scary costumes and it's all make believe" Daphne explained.
"Like I guess that makes me feel better," Shaggy replied.
"There you go, that's the old Halloween spirit guys: now let's check out the rest of the carnival" Fred remarked.
With that Fred, Daphne, Velma, Shaggy and Scooby began exploring the rest of the event; all over the carnival grounds there were hundreds upon hundreds of rides, game booths as well as every kind of food concession that you could imagine, which made Shaggy and Scooby quite happy.
However, unknown to the five sleuths, two people were watching them from behind a nearby building; for now the gang didn't see the two people, but you could tell they were there, because as the late afternoon/early evening sun shone across the grounds of the Coolsville Halloween Carnival, for a brief moment the figures of the pair could also be seen to everyone in attendance, although most of the attendees of the event didn't seem to mind or even notice the pair, but whether the attendees of the carnival could see them or not, they were still there.
One of the pair is a dark brown haired young man in his mid twenties, he wears a simple blue t shirt, along with black jeans and black shoes; the other half of the pair is a light brown haired young woman in her mid twenties, who wears a simple navy blue dress and skirt with light green high heeled shoes; the young man and woman would look to be your average every ordinary young people, but in reality they were not your typical young adults; the truth was that the two of them were a brother and sister named William and Linda Christensen, the brother and sister lived in the majestic Pacific Northwest: Seattle, Washington to be exact and were taking a road trip to see the country before they finished their training.
Now you may be asking yourself: if William and Linda are in the mid twenties, they would be done with high school and college by now; while it was true that they completed their mortal schooling, in a few weeks they would begin their education at the Salem Institute of Magic, where most young witches and warlocks would go to learn how to use their powers properly and to never abuse them; although so far Linda and William had been very good at using their magic, their parents insisted that they go to the school for more training, just in case.
However, Linda and William's final leg of the trip happened to occur on Halloween and as a result they both wanted to be extra careful in case something happened to them or to the city of Coolsville, which they drove into early that day; before they left on their journey they had done some research on Coolsville and had found out not only that they had one of the largest Halloween celebrations in the country, but they also found out that it was the home to Fred, Daphne, Velma, Shaggy and Scooby Doo, collectively known as Mystery Inc., who were celebrities even in the world of magic and the supernatural which the brother and sister sorcerer and sorceress were involved in and were experts in.
While they were looking forward to their time at the Salem Institute of Magic, the brother and sister had always loved Halloween, ever since they were little and ever since that time they would use their magic to create the most perfect Halloween costumes anyone had ever seen, which would always make people in their High School or at various parties they attended very jealous, because it always seemed like no one could ever top their costume ideas.
As the brother and sister watched Scooby Doo and his fellow mystery solvers walk through the Coolsville Halloween Carnival, the sibling sorcerer and sorceress began discussing what they were going to see at the event before they left for New England and also what they were going to say to Scooby Doo and his friends when they met them, because after all they were as big fans of the gang as anyone could be, much less a witch and warlock.
"William?" Linda asked.
"What's up sis?" William responded.
"This is sure fun huh? I mean getting to see the Coolsville Halloween Carnival" Linda replied.
"Sure is Linda, I mean I've always wanted to visit here, and not to mention Scooby Doo and his friends" William remarked.
"Yeah, that was sure a stroke of luck that Mystery Inc. is at the carnival at the same time that we're here; I wonder, I wonder what they're like" Linda replied.
"What do you mean Linda?" William inquired.
"Well, I mean I've always wanted to meet them, and I've always wondered what their personalities are like, what their likes are, what their dislikes are; and maybe what they like the guys of the group like in a girl" Linda explained, brushing her light brown hair aside as she spoke.
"Linda, Linda, Linda; do you really think either of the guys in the group are really going to be interested in you? Because according to what I've read Fred's dating Daphne, and Shaggy's dating Velma, although…." William replied.
"Although what?" Linda asked.
"You know, I would mind knowing what the girls of the group like in a guy myself; to tell the truth I always had a little crush on Velma myself, maybe she'll consider going out on a date with me" William replied.
"William, if Fred or Shaggy won't consider dating me, then what chance do you have with Daphne or Velma?" Linda inquired.
"Well, it's nice to dream isn't it?" William responded.
"Good point William, good point; so what should we do now?" Linda asked.
"Simple my dear sister, we take a look around and have some fun, right?" William remarked.
"Sounds good to me" Linda responded.
So with that Linda and William proceeded to move from behind the small building where they were hiding and walked out onto the carnival grounds to continue their time at the popular Halloween night event.
Now Halloween, or All Hallows Eve if you prefer had always been a night of danger, mystery and fun for the group of sleuths known as Mystery Inc., but on this Halloween night, unbeknownst to them at the moment Scooby Doo and his friends were not only about to meet a sister and brother pair of sorcerers, but they were also about to get themselves involved in a mystery unlike anything they had ever encountered in their entire detective careers, one that if left unsolved could result in untold horrors plaguing the world as we know it.
Author's Notes: Sorry if this chapter is really, really short; although there might be a few other chapters in this story that are short as well, most of them will be pretty long; hopefully everybody likes this story and will enjoy the rest of it, also hopefully everybody reads and reviews my stories as always.
