HUGE SHOUT OUT TO PHANTOM1 FOR HIS WORK AS A BETA, GREAT JOB!!

Susan Ivonova was standing at her normal post in C&C enjoying a quiet day for once. Well as quiet as can be expected after the murder of President Santiago by Vice President Clark. It was widely known but was proven true by Clark's actions and his new xenophobic and totalitarian shift in government policy. President Clark used a military incident to declare martial law an Earth and all of her colonies. This had triggered a war of independence on Mars that had been brewing for decades.

In response, President Clark ordered the bombing of the domed cities on Mars to try to bring them back under his control. All that it did was cause other outlying colonies to declare their independence as well, including Babylon Five. That was yesterday. Now they had to be prepared for when Clark would send ships to try and retake Babylon 5, they all know he would, they just don't know when.

She was about to tell a Drazi cargo ship that they have clearance to dock when all of a sudden, in a flash of blue light, the most incredible thing she has ever seen appeared.

"Mr. Corwin, tell me I'm not seeing things! Tell me a HUGE city just appeared in front of us out of nowhere!" He responds by just shaking his head yes with his mouth hanging open. Snapping out of it she starts barking orders to her shocked staff. "Hail that ship err…cit…Close the blast doors! Launch zeta flight and have them target it. Activate defense grid and will someone PLEASE get the commander up here! Let's move people. Sensors, what type of readings are you getting from that thing?"

"Ma'am the only thing that we can read is that it is there, it's huge, and its power readings are off the charts!! We also ca…"

The sensor operator was cut of as all of a sudden the lights started flickering on and off and all the consoles started to flash on and off.

"What the hell is happening people!?!? Are they attacking us?" Just then Captain Sheridan stumbled out of the lift due to the station's systems fluctuating.

The sensor operator decided to make his report. "Sirs, the ship is heavily scanning us. Their scanners are of a type that I have never seen or heard of. It's causing signal interruptions on everything except the heavily shielded systems. Most of them will be ok but some systems will need to be replaced."

A technician from the other side of C&C shots out his report. "Sir, all targeting scanners are offline!"

The first words to be heard were from Sheridan, "Great, just what we needed."

A Few Minutes Earlier – Onboard Camelot

Harry felt a slight shudder as Camelot reappeared into normal space. From his seat in the control chair, he could see that he reappeared right in front of a huge, spinning space station. "Must not have artificial gravity…" he said to himself. Using his mental connection to the city and her systems, Harry began to scan the station.

After a minute of detailed scanning Harry stopped it. His scans told him several interesting things. The most shocking was the lack of any type of shielding technology. He second was that there are several dozen different species on board, and the third was that their limited weapons would be so ineffectual against him that he wouldn't even need shields if they were to fight, not that he wouldn't use them.

Another interesting discovery was the lack of any subspace communications of any type. It just wasn't like they weren't using them it was like subspace technology just didn't exist in this dimension. All of a sudden he noticed twelve small craft approaching Camelot. His sensors designate them as small single pilot fighters. Harry also picked up on the directed tachyon emissions that are being directed at him from the space station. These emissions seem to have a digital modulation to them and the city recognizes it as a type of communication frequency. With just a mental command, one of the backup subspace antenna's was configured to send and receive using tachyons.

"…is B…on 5 to u…ied vessel, d…ou read. Your scans ar…ferring with our system……ease stop…"

Harry frowned at this garbled message. He mentally kicks himself for not realizing earlier. Due to the nature of subspace technology, components not properly shielded from them will cease to function properly. Harry immediately stopped all his scans of the station except for the passive ones. He wasn't worried about a sneak attack since his shields were up. Harry opened a communications channel, audio only to the space station.

"This is Harry Potter on the City ship Camelot, I would like to apologize for the disruption of your systems, it was not intentional, please respond."

After a few moments a man's voice could be heard responding. "This is Captain John Sheridan, Harry is a human name, are you from earth?" Surprise could be heard in his voice.

"You could say that I am from Earth just not yours. I come from a different dimension in search of new technology and allies. As you can tell my technology is radically different from your own and that should lend credence to my claims. Did my scans damage your systems in any way? If so I would like to offer my assistance in repairing them and I would like to come over so we can talk face to face."

"Your scans did damage some of our systems; most noteworthy is our targeting scanners so we are left defenseless except for our fighters, we call them Star Furies. You are more than welcome to come on board; we just ask that you move your ship to orbit over the planet closest to us. Over."

"I will move my ship to the planet as requested and will also offer to put you under my protection till repairs can be completed to your scanners. Will one hour be acceptable to you?"

"Tentatively, your offer for protection is acceptable. We will be awaiting your arrival in one hour, Babylon 5 out."

"Camelot Out."

Harry closed the channel and thought of the conversation that just transpired. 'So the station's name is Babylon 5 and the commander is human. They are left defenseless so I'll just have to protect them for the time being. If everyone's technology is along the same line as there's that shouldn't be a problem. Ok first things first, lets get into orbit of the planet.'

OUTSIDE B5

All civilian traffic had stopped and marveled at the City Ship as it had suddenly appeared without any warning. Everyone was shocked at the beauty, size, and implications of such a feat of ship construction. It spoke of technology way beyond anything any of them have ever seen. All the ships representing different governments sent a message back to their respective worlds with the results of the scans that they were able to achieve, which wasn't much. Within hours, every government would know of the magnificent city ship with its tall spires and domed sections in the shape of a snowflake with the golden colored shield protecting it.

All of a sudden, to the shock of everyone watching the massive City Ship accelerated faster than any fighter anyone had ever seen and went into orbit around the Epsilon 3. Once in orbit, the ship slowed down and looked to be barely moving above the dark planet. Everyone is awed by the agility of such a massive construct.

Though there were many questions regarding the appearance of this new ship, one thing was certain: A new power had arrived and no one knew what to expect from the people that could build something of that magnitude.
