Cheyenne Mountain Complex, Earth

"Run that by me again, please?" Mitchell sighed, holding his hand on his face, "Time… changed? What are you talking about?" He was getting tired of this questioning. It seemed to him like they were losing information the longer they interrogated her, and it was giving him a headache.

"Sure. Time just changed. Teal'c here just gained a pound or two, Jackson's hair is shorter, and you lost a few pounds. Satisfied?" responded Ace. "And I already told you all I can tell you. The Cybermen are coming and I am here to stop them. We need to get ready for them to head here, befor-" but Ace was cut off by blaring alarms. General Landry's voice began to speak through the intercom, in a harsh and fast tone.

"This is General Landry. All personnel must report in now. The complex is compromised. I repeat, all personnel need to check in now. SG-1, get your backsides up to me now, got it? The rest of you check into your quarters. We will find the intruders."

Daniel, Mitchell, and Teal'c all looked at one another and stood up. As they left the room, Ace called after them, with a slight hint of worry in her voice, "This here is your typical military bunker. Whatever's in here knows how to get its way around, probably just as well as you to. Watch out."

The three of them strode to the conference room, arriving after Vala and Carter. General Landry turned and looked at the team. "Carter, would you like to explain your results to these men. And then let them know what the Sun Tzu picked up on its long range sensors."

"Yes sir," Carter said as she stood and walked to the screen, on which was displayed the results of some kind of computer program. "A few hours ago, our network's diagnostic program identified some kind of power drain, though where the drain was couldn't be pinpointed till a couple of minutes ago. The results suggested that something, unknown to our database, was draining power and building something in the sub-basement. Landry gave the order for check in as soon as I told him to, and that section of the base was locked down.

He was planning on sending us in, until Sgt. Harriman got word from the Sun Tzu that something massive, at least as large as Earth, is hurtling toward us in Hyperspace. We are scrambling all of our defenses, and Russia and China have already been alerted. The Sun Tzu, Daedalus, and Odyssey are all on their way to Earth to defend it, but we don't know what they can do against a planet sized missile."

A muffled explosion shook the room, knocking the occupants to the ground. "What the hell was that?" yelled Landry. "Get security down to wherever that came from, now!"

"Sir," called out Sgt. Harriman, "it came from the sub-basement. Whatever is down there is loose now."

"Mitchell, Teal'c," Landry shouted, spinning to face them, "get a team together and down there now! I want whatever that was contained and out of the way."

Another blast was heard, and Harriman called to the team and Landry: "Gas attack, sir. Whoever it is just gassed the gate room, and they're on their way up to this level."

"Pull back to the secondary control room, now!" Landry hollered, "Mitchell, Teal'c, forget my previous instructions. Just get the scientists and staff out of this level now!" Mitchell and Teal'c shot out of the room, grabbing weapons from two waiting soldiers and training them on the stairs that descended into the gate room. Through the gas, that was drifting up from below, Mitchell could just make out five shambling figures. Mitchell waited to fire until he could make out the figures more clearly; when he finely got sight of them, he was shocked. 3 of them wore janitor outfits, but the other two were in air force uniforms. The real shock was seeing their faces, or rather, the lack thereof. Metallic Cybermen heads adorned each persons body, though each person's former features stood out through the mask. Their hands were also metallic, crackling slightly with electricity.

"Open fire!" Mitchell commanded, unleashing a salvo of bullets on the nearest two, and the bodies were shredded like ragdolls. However, the twitching remains began to crawl towards the soldiers, and several soldiers were hit with blasts of electrical energy, collapsing onto the floor.

"Colonel Mitchell, I suggest pulling back. These things are still moving and able to kill, even when we have emptied entire magazines into them," Teal'c said, in between salvos. "We need to pull back and seal these doors. Sgt. Harriman has already locked down the Iris override controls, so they will not be able to escape."

"Alright Teal'c, tell the men to fall back," responded Mitchell as he emptied another magazine into a fourth Cyber-person that shambled up the stairs, "I'll cover for you. Go, go!" Teal'c turned and gave the retreat order to the men, and they sprinted for the stairs. Mitchell grabbed one of the guns off a dead soldier, trained both of his weapons on the stairs that unloaded as he sprinted backwards, dodging to blasts of electrical energy. He managed to jump through the doors of the elevator just in time, colliding with the legs of the other soldiers. "Alright, does anyone know what the heck just happened," Mitchell asked, voice hoarse from shouting. "How the heck did those Cyber-things get into the SGC?"

"I do not know Colonel Mitchell, but perhaps Daniel Jackson or Colonel Carter will know the answer when we find them."

"I sure hope so, Teal'c, cause we still have that giant planet moving through hyperspace directly toward us," Mitchell retorted, then continued under his breath as he got off the elevator, "Could this day get any worse?"

The first thing Mitchell saw when he got off the elevator was Carter's face, worry creasing her features. "Mitchell, we have more problems. The Cyber-things were able to access the gate, and they've sent off some kind of subspace pulse in the direction of the planetoid object that we were tracking."

"Oh, this day keeps getting better and better," Mitchell grumbled under his breath. "Let's get to work on locking down the lower levels. We can deal with those things after we've saved ourselves from the certain death of the planet collision that's about to happen."

Telos, planetary command room

"Cyber-Controller," began CL-3, "We have just received word from the Cybermat on Earth. It has successfully used Cyberslaves to capture the Stargate of the human military complex. However, it has discovered something troubling."

"Continue, Cyber-Leader, what could the humans possess that could defeat us? They would have used it by now if they were able to."

"Controller, it is not a weapon. It is… a … companion… of the… Doctor…"

"WHAT?!" the Cyber-Controller exploded, but quickly collected himself. "A companion of the Doctor, how is this possible? We have taken every precaution. The Doctor could not have followed us."

"Nevertheless, Controller, it is a companion of the Doctor, designated 'Ace.' We have encountered her multiple times, most notably during the events on Earth referred as 'World War II,' and during the attempted acquisition of the Validium."

"We will have to act quickly. Instruct the Cyberslaves to destroy the Doctor on sight, and instruct all Cybermen the same. We will not let him foil our plans again. The Cybermen will survive. We will rule. We shall turn Earth into the new Mondas."

"I shall obey, Controller. We will not allow anything to come between us and our goals." The screen shut off, and CL-3 was left alone in the control, mentally directing Telos toward its ultimate destination. Within Telos, the creature that was the Pilot languished in pain, disconnected from all outside stimuli, its only joy being the knowing of what was coming.

Secondary Control Room, Cheyenne Mountain Complex, Earth

After the evacuation, SG-1 had gone with Sgt. Harriman and General Landry to the secondary control room, so that they would be able to monitor both the incoming planetoid and the now sealed lower levels. The data coming in was glum. Thirty soldiers had vanished in the hasty retreat, and another 10 had been killed. To top that off, computer firewalls began to fall as the Cyber-things hacked into the SGC mainframe like a hot knife through butter.

"This is weird," Carter mumbled, and she began to type. "The Cyber-things down there are searching our database, and the Asgard database, for the term, 'the Doctor.'"

"What, like a doctor? Why would they search for a doctor?" Daniel asked, curiosity evident in his features.

"No, like a name, or a title. Wait, they found something." Carter began to furiously type, and on one of the large monitors, a file appeared. Carter scrolled slowly through it as she spoke: "They chose one of our Atlantis files; one about dimensional transcendence and a blue… box?" Carter furiously began to type again, but she didn't put anything else on screen. "That's, that's it… They aren't looking for anymore files. And they just sent out another subspace pulse from the Stargate, again in the direction of the planetoid. "

"Hold on, hold on, what 'blue box' thing are we talking about?" Mitchell asked, gears almost audibly turning in his head. "What's so special about this thing that Atlantis would send the file to us?"

Before Carter could speak, Jackson cut in, "It's some kind of discovery the Ancients made. The most we could get from the data was stuff about engineering pocket dimensions, and something about a 'tempore Dominus,' but we could never make sense of it. 'Lord of Time' made little sense, even though now we know that the Ancients experimented with time travel."

"Lord of Time? That sounds, mysterious…" Vala smiled, the familiar gleam coming back to her eyes.

"Not that this isn't interesting or anything," cut in Mitchell, "but we still have hostiles in the lower levels, a prisoner in the cells, and a load of futuristic tech lying in Sam's lab. Let's get moving people."

Telos

The view screen clicked on again, and the Controller's helmeted head filled it. "What has occurred that you would open communication with me yet again?"

"Controller, we have obtained all knowledge that the humans possess of the Doctor," CL-3 responded.

"What have the Cyberslaves discovered?"

"The humans know nothing of the Doctor, and his only reported sighting was several millennia ago. He will not trouble us."

"Excellent. Prepare to move Telos a safe distance from Earrth once it arrives. We need to human population alive for conversion. Prepare the power draining equipment, our soldiers will need the extra power."

"I obey, Controller." A flash of light lit of the monitors within seconds of CL-3's response to the Controller. Telos had arrived in the Sol System, just outside of the orbit of Pluto. The sublight drives kicked on, and the planet began to move through the system, slowly avoiding close proximity with any of the other planets, Earth in its sights. If the Cyberslaves had been paying attention, they would have noticed a whirring, wheezing noise within the sealed off buffer zone of SGC level 26. A blue box materialized in the stairwell, and the door creaked open.
