Buffy-1 year after S7 Angel-right after S5 ended Harry Potter-right after HBP battle Charmed-right after S8 ended Alias-right after S4 Mists of Avalon-before Mordrid left Morgause's house.
All of a sudden Buffy found herself standing on a beach with small waves crashing at her feet. As she looked around she saw that she was not the only one there or the only one that looked measurably confused. In fact there seemed to be near a hundred people all crowded on a small beach. As she started to examine the faces she recognized about a score of them. Just moments ago she was in the Louvre and now she was surrounded by people she hadn't seen in years.
"Buffy," the British accent was hard to miss, Giles was approaching her with Willow and Xander at his sides.
"Giles, what happened, where are we?" Buffy wanted to know.
"Well, I don't know honestly, all I do know is that I was in my study going over an ancient text and then suddenly I was here."
"I was at the movies, and believe me, we aren't missing much. It looks like the old Scooby Gang's back together," as far as Xander could see there was Giles, Willow, Buffy, himself, Dawn, Faith, Kennedy, Oz and Riley along with some that were supposed to be dead. Jenny, Kendra, and Tara were coming down the beach when he saw her, there was Anya.

"What the bloody hell was that?" Spike looked around at Angel, Gunn, Illyria, Connor and Wesley and they were in the same state of shock as him. They were all prepared to go to their deaths when BAM, they were on a beach. Not only were they all there but he also saw Lorne, Cordelia, Doyle, and Fred, some that were no where near them a few minutes ago and some that were dead and supposedly gone. It was as Spike regained his composure that he realized; he and Angel were out in the sun, without the Gem of Amarra, and were not burning.

"Oh, no, no, no, no. THIS IS NOT HAPPENING!" Piper was livid. They had just finished vanquishing Christy and the Angel of fate had returned Leo. Things were supposed to have let up, at least for a while, but this was most definitely not the normal life she had in mind.
"Where are we?" Paige was dumbfounded.
"I would wager we're not in Kansas anymore Aunt Paige, or San Francisco either."
"Chris, Wyatt, you're here too?" This time it was Phoebe's turn to speak.
"Not just us. Look, there's Grams, Great Grams, Dad, Uncle Coop, our white-lighter Kyle, the girls, Cole and, wait a minute, is that---"
"Prue?"

"What in the names of Hecate, Zeus and Poseidon happened?" This time it was a bushy-haired Hermione who spoke, getting up from the ground and brushing off sand from her robes. "Ron, Harry, are you two okay?"
"I think I'm fine." Ron blurted out.
"Me too," Harry chimed in, "It seems that we have been taken away from Hogwarts."
"Thank you for that rewarding insight, Harry, but I think I'd already realized that," Hermione was a little on edge, "was it a portkey, who are all these people."
"Well, I'd venture to say that it was not a portkey and that everyone here is extremely confused." The Golden Trio turned around to see Albus Dumbledore, who mind you was supposed to be dead, and were in utter shock. "Yes, I know. I died but a strange occurrence befell me and I felt myself moving through time at a rapid rate, surely you recognized the sensation from the time-turner Miss Granger. I do believe that we are in the past, although when I do not know. Oh, do stop standing there so immobile, I am here now and to my knowledge am fully alive and in the flesh."
Lupin, Dedalus Diggle, Elphias Doge, Aberforth Dumbledore, Mundungus Fletcher, Hagrid, Hestia Jones, Minerva McGonagall, Moody, Sturgis Podmore, Kinsley Shacklebolt, Tonks, Arthur, Bill, Charlie, Molly, Poppy Pomfrey, Seamus, Madam Sybill Patricia Trelawney, Ted Tonks, Viktor Krum, Ginny, George, Fred, Fleur, Dennis, Dean, Colin, Cho, Andromeda, Luna, Neville, Percy and Penelope all appeared just at the bottom of the beach.
The Order members saw Dumbledore and were approaching when Remus saw something that made him confused and ecstatic at the same time. Alice, Frank, Edgar Bones, Caradoc Dearborn, Benjy Fenwick, Marle McKinnon, Dorcas Meadowes, Gideon and Fabian Prewett and James and Lily were hugging and greeting each other.
"James, Lily." Remus ran to his old friends.
The whole scene was of shock and amazement. Neville was being approached by quite sane parents as was Harry and Molly was near fainting over her older brothers whom she had not seen in over twenty-five years.

"Sydney, are you alright?"
Everything was a haze as Sydney awoke. She was lying in a fur covered bed and Vaughn was looking down on her. "What happened?"
"What's the last thing you remember?"
"We were in the car going to Santa Barbara, and you said you had something to tell me, you said that you aren't Michael Vaughn: What's going on?" Sydney was beginning to panic.
"I told you the truth. My name is not Michael Vaughn and I planned to meet you very long before you walked into the CIA."
"Wha-"
"The year is 470 A.D. and we are on the Isle of Avalon in Britannia. A great evil is coming, no it is here now and we need your help. Rambaldi wasn't just talking about the future, you are needed here." He was trying to be sensitive but also convey the urgency that they needed.
"What are you talking about, if you're name isn't Michael Vaughn then what is it?"
"You should know that Jack and Nadia are also here and that I am the son of Viviane, Lady of the Lake, my real name is Lancelot."
