Author's note: This story is set during the Warehouse 13 episode "When and Where" (2.10) and between The X-Files episodes "All Souls" and "The Pine Bluff Variant" (5.17 and 5.18), and assumes knowledge of both series up to those points.

Through the fog of his (incredibly pleasant, salaciously naughty) dream, Mulder heard a faint, insistent ringing noise. With near-Herculean effort, he shook himself awake, fumbled his cell phone off the coffee table, and quickly glanced at the caller id before answering. He hoisted himself up until he was in a position that could have generously been described as sitting, and muttered blearily into the phone, "Frohike? It's three o'clock in the morning. What do you want?"

"Mulder, we're sorry, but we have something we need you to look at," Frohike said before he paused, not quite sure how to describe what the Gunmen had picked up while surfing their satellite feeds and exactly why they were waking Mulder up at three am.

Luckily for Frohike, Langly quickly interjected. "Yeah, there's some weeeiiird electrical energy bleeping in and out in the middle-of-nowhere South Dakota. It's packing some serious punch, man."

"Mulder, whatever is causing this electrical disturbance is huge. We have no way of knowing what's causing it, but whatever it is, it seems to be located inside a giant abandoned warehouse. This warehouse is located at K39ZZZ on the North American Grid, in the middle of South Dakota, but we can't find any records of it ever existing. And trust me, we've looked everywhere."

Byers gave Mulder a few seconds to absorb what he had said, and when he didn't respond, Byers continued.

"Mulder? This isn't your average hum from a power plant. This is coming in short, random, and extremely powerful bursts. We've been monitoring it for about fifteen hours. The first surge was at 9:15am Mountain Standard Time, and they've been coming pretty steadily since then. A few hours ago the readings were off the charts, but the pulses seem to have normalized for the time being."

"Something super gnarly is going on out there, Mulder, and I don't think this is a job for your friendly South Dakota power company," Langly cracked, trying to add a little levity and hoping Mulder didn't kill them for waking him.

Mulder had finally woken up enough to process what the Lone Gunmen were telling him, and his mind began to rifle through previous X-Files, trying to come up with possible causes for what the Gunmen were telling him. He didn't find much.

"Have there been any reported UFO sightings in the area?" he asked hopefully, if a bit groggily.

"None that we've found," Byers supplied, as he, Langly, and Frohike breathed a collective sigh of relief. They'd only woken Mulder up this early a few times before, and each time they'd known more about what was going on than they could even begin to guess about this situation in South Dakota.

"We've checked all the databases, both local and national, but not many people live out there. The closest town to this old warehouse is Univille, and there hasn't been a single reported UFO sighting there since the fifties," Byers finished. In situations like this it was better to let Byers do most of the talking. Frohike had a habit of mumbling, and Langly tended to ramble, both things that were not too wise when dealing with a prematurely awoken Agent Mulder.

Mulder reached up, ran his hand through his hair, and blinked, trying to clear the sleep from his brain. "Alright guys. I'll be there in an hour to look at what you've got."

Warehouse 13
Near Univille, South Dakota

Claudia jogged back to the H.G. Wells section where Pete and Myka were strapped into Helena's time machine. "Alright, I hooked up the machine to the main power grid," she told Helena. "That's definitely enough juice for it to run the whole day."

I hope, she thought grimly. She wasn't quite sure how much strain Helena's time machine would place on the Warehouse's power supply or what exactly would happen if the circuits failed.

Artie's gonna end us in a serious way if he finds out about any of this. But it's obviously safe because Helena's used it before… right? Quickly shaking herself from that disturbing train of thought, Claudia stepped off of the platform and over to the time machine's control module to prepare to send Myka and Pete back to 1961 to gather intel on the "Glass Girl" artifact.

"So… is there a big countdown?" Pete asked uneasily.

Helena grasped the lever that would activate the machine, looked at Pete, and simply replied, "No," before pushing it down. Myka had her eyes locked on Helena's, silently praying that the inventor would keep her safe on their journey into the past. She didn't have long to pray, or to look at Helena, however, because the platform began to hum and crackle with electricity, spinning and slowly picking up speed. Suddenly there was a blinding flash of lightening above the machine and Pete and Myka found themselves in Jack and Rebecca's bodies in 1961, in the smoky, bustling past of what would one day become Artie's office.

Scully couldn't even begin to count the number of times she had been jolted awake in the middle of the night by a loud, insistent knock on her front door. Still, every time it happened she bolted up in bed with her hand half-way to the nightstand, scrabbling for her weapon, panicked that someone, or something, was breaking into her apartment. But every time (almost every time), all she found upon standing on tiptoe to look through the peephole was Mulder's goofily excited face staring back at her expectantly. Her first thought was always, I should really get him a key, followed by, That would be a terrible idea. Then he would just barge in and scare the shit out of me before I was properly awake. Wouldn't want to accidentally shoot him.

She sighed and pulled her robe more closely around her body as she slid the chain off the door and twisted the deadbolt. It was five forty-five in the morning; she still had a good half hour of sleep left before her alarm went off, telling her she needed to stumble out of bed and drag herself into the shower to get ready for work. Hoping against hope that Mulder was at the door of her apartment for some innocent, completely benign reason, she only pulled the door open wide enough to lean against the frame while giving Mulder her best "What the fuck are you doing here?" expression.

After almost five years of being Scully's partner, Mulder should have been immune to that withering look. And he was. Almost. So he took a moment to look utterly sheepish for waking her up and then launched right in, outlining everything the Lone Gunman had told him about the mysterious electrical surges, the warehouse that didn't officially exist, and finally ending with, "I booked us two tickets out of Dulles to Rapid City Regional at seven thirty. We have to get there soon, because the Gunmen said that the electrical energy keeps escalating."

"Alright, Mulder." Scully motioned him inside, walked back into her bedroom, and began to change into a suit, calling to Mulder from beyond the closed door. "But what do you think it is? What would cause the type of electrical disturbances you're describing?" Scully asked him, puzzled. She'd worked with Mulder long enough on the X-Files that she was reasonably confident of her knowledge of paranormal phenomena, but she'd never heard Mulder mention anything similar in scale or frequency.

As she walked out of her bedroom with her overnight bag, Scully could feel Mulder's brain revving into high gear as he began to rattle off the possibilities, ticking them off on his fingers as he went. "It could be any number of things, Scully. It could be a testing site of some kind, it could be a downed UFO, it could be a sight that's overrun with ghosts, it could be a storage facility for alien technology, it could be…"

"You don't have any idea what it is, do you?" Scully's remark was more of a statement than a question.

"Well… I've never seen anything like it, no. But I have a feeling it isn't something you'd find in Science Weekly."

"Then let's go out to South Dakota and figure out what it is."

Mulder grinned at her and ushered her out the door of her apartment with his hand resting on the small of her back.
