Hey, guys. I am back, with the first chapter of my Flash-Dr. Strange fanfic. I am very excited to get started on this. This story will also finally explain how Harry, and Gypsy, really know about Earth-99, and why they're scared of it.

Alright! Let's get to it!

Chapter 1- Dr. Strange

Barry stares at this new arrival, just shocked. "Dr. Strange?" he asks cautiously.

"That sounds like a bad nickname," Cisco says.

Strange looks at Cisco. "Well, it's my real name. So, don't poke fun," he says.

"Okay. Who are you, really? And what the h*** are you doing in my house?" Joe demands.

Dr. Strange looks right at Barry. "You spent a year on another Earth about a year ago, didn't you, Barry Allen?" he asks.

Barry looks at him, stunned. Not only because he knows his name, and that he's the Flash, but also that he knows he was on Earth-99.

"Yes, I did," he says slowly, before asking, "How did you know that? And how do you know who I am?"

Strange smiles a bit. "Because. Flash. I'm from Earth-99 too," he says.

Barry stares at him in shock. "You're from Earth-99?"

Strange nods. "Yes. As I said. My name is Dr. Stephen Strange. On my Earth, I was a world famous surgeon. But, I was involved in car accident that led to me being unable to use my hands."

"My path to try and fix my hands led me to Nepal. There, I met a secret society. The Masters of the Mystic Arts. By your definition, they would be called wizards or sorcerors. They harness energy from the multiverse to make magic. I trained under a woman known as the Ancient One, and ended up taking her place when she died. I heard of you, Flash, while you were still on my Earth, and I did my research," Strange says.

Barry looks curiously at Strange. "Okay. That explains who you are. But, why are you here?" he asks.

"To help you save your world," Strange replies.

"From what?" Barry asks.

"On my Earth, one of the Ancient One's old pupils, named Kaecilius, turned to the dark side, as you might say. He swayed a number of the other students to his side. They called themselves the Zealots. They felt the Ancient One had not showed them all the truths she had promised, and that they had found a way to immortality," Strange says, before pausing.

"And what was that?" Cisco asks.

"There is another dimension, which exists beyond the multiverse. It is called the Dark Dimension. And it is ruled by a being known as Dormammu. The Cosmic Conqueror. His goal is to merge worlds with the Dark Dimension, devouring them and boosting his power with them. The Zealots raided the great library of the Masters of the Mystic Arts, and stole pages from a book. Those pages contained the instructions on how to contact Dormammu and draw power from the Dark Dimension," Strange says.

"Why the h*** would they do that?" Clint demands.

"They believed that when he conquered Earth, that Dormammu would grant them immortality and far greater power than they ever could gain otherwise, for the Dark Dimension exists beyond space and time. But, an obstacle stood in their way. The Masters of the Mystic Arts have long been aware of Dormammu. They built three Sanctums on Earth to generate a barrier around Earth which would keep Dormammu at bay. From what I understand, the ancient Masters also travelled to as many known worlds of the multiverse as they could, erecting Sanctums to protect those Earths."

"When you arrived on Earth-99, you drew the attention of Dormammu. And when you returned to this Earth, he was able to figure out where you came from. He sensed the power this world offered, and became determined to devour this world."

"When Kaecilius and the Zealots rose, I had just begun my studies with the Ancient One. I assisted them in defeating Kaecilius, and got Dormammu to make a deal with me in that he would leave Earth-99 alone. As part of the deal, Dormammu brought Kaecilius and his Zealots into the Dark Dimension, making them his slaves for all eternity."

"However, one of the Zealots escaped from Earth-99 prior to the rest of the them being sucked into the Dark Dimension. And he came to Earth-1. He's been here for several months, recruiting followers and training them in the ways of the Mystic Arts. Once they are strong enough, he intends to lead them to destroy the Sanctums here on Earth-1, and bring Dormammu to this Earth," Strange finishes.

Barry stares at him, stunned. Finally, he says, "This Zealot is now training more just like him to try and unleash Dormammu on this Earth?!"

Strange nods. Then, Caitlin asks, "What about the Sanctums? Who's protecting them? Are there sorcerors like you on this Earth?"

"No. There used to be, but there were never very many of them, and they died out. So far as I've read, an organization known as the League of Assassins took over the duty of watching out for the Sanctums after the Masters on this Earth died out," Strange says.

Everyone looks around at each other. Finally, Barry looks back at Strange and says, "Then, that's a problem. The League of Assassins was disbanded about two years ago. Some of the members may be protecting the Sanctums, but not as many as before. We're in a lot of trouble here."

Strange looks concerned. "If the Sanctums are not protected, then we need to get to work finding the remaining Zealot and his followers, and protecting the Sanctums ourselves," he says.

Barry looks at Strange for a moment. Then, he smiles. "Well, I'm not about to let some extra-dimensional monster destroy the Earth. What about you guys?" he says, turning to the rest of the team.

Cisco grins. "Definitely not. And if I get to see magic in action...even better!"

Clint grins. "Yeah. I'm down," he says.

"I'm gonna help too," Caitlin says.

"Count me in," Wally says with a grin.

Barry turns back to Dr. Strange. "Well, Dr. Strange. You've got Team Flash on your side for this round," he says with a grin.

I'll end there. I know. Probably not the best chapter, but I hope it was a good starting chapter. Let me know of any ideas you have that may make it better.

I had always planned for Dormammu to be the villain. I thought Sanctums built on this Earth by the Masters were the best explanation for Dormammu not finding Earth-1 for this long. And since I wasn't sure about having Masters of the Mystic Arts on this Earth, I decided to make the League of Assassins take the role of guarding the Sanctums, and explain why Dr. Strange had to turn to Team Flash for help.

I hope you're as excited for this story as I am. I may be a little slow on the updates, since I'm still working on what the whole plot is gonna be. But, I'll try and update as soon as possible.

I'm also working on the Thor-Arrow story. The first chapter will be up soon. Until then, keep an eye on this one, and go check out my new Harry Potter story I'm working on.

Please review and stay tuned.
