The following day...

25th of April, 2:00

In a convenience store near Royal Marines Base Poole, Poole

A man walked into the convenience store, but he was left disappointed after finding out that almost every single shelves were empty. He sighed and grabbed whatever is left on the shelves. Yesterday was certainly a bad day, not only for him but also for the others.

???: "Is this all that's left?"

Cashier: "This is all that's left, mate. You can try your luck elsewhere but it's probably going to be the same."

???: "Okay..."

Just as the man was about to hand his money to the cashier, his phone rang. He immediately picked up the phone before placing the money in the cashier's hands.

???: "...Got it, see you in ten minutes."

The man hung up on the phone before walking out of the restaurant with the snacks he has just bought in a hurry.

At the same time...

In the garden of 10 Downing Street, London

On a bench in the garden of the residence of the Prime Minister of the Franco-British Union is an old man, trying to finish a stack of papers regarding the "Teleportation Crisis" as it's now called by the public and the media.

Beside him were several cups of coffee, the old man was determined to read every single report before tomorrow morning.

That was until he was approached by a man with an unmistakable face. It was the Chief of the Defence Staff, Sir John Campbell. The old man on the bench was none other than Josué Garreau, the current prime minister of the Franco-British Union.

Campbell: "You should've been sleeping, Josué."

Josué: "Not until I finish reading all these reports, John."

Campbell sighed before sitting down beside his friend and colleague who was still focused on reading the reports.

Campbell: "How's Milena doing?"

Josué: "She's fine, John. Although it took me quite some time to calm her down yesterday."

Campbell: "I see."

Josué: "So what are you doing here, John?"

Campbell: "I figured out you would still be working around the clock like you often did when you were still in the army, so I stopped by, just to check on you."

Josué: "Understandable."

Campbell: "I guess, that's it then."

Josué: "Are you sure that's all?"

Campbell, after a short pause: "No. We've just regained communications with the Royal Gibraltar Regiment and 2nd Battalion, Royal Gurkha Rifles stationed at Gibraltar and the news is rather worrying."

Josué: "What's it, John?"

Campbell: "Our troops have engaged combatants of an unknown nation in a village just north of the Gibraltar-Spain border."

Josué: "What do you mean? Isn't that where the Spanish town of La Línea de la Concepción is?"

Campbell: "We won't be sure until the satellites' launch today and more importantly, Josué, don't forget that everything outside of the borders is no longer the same."

Josué: "...Right."

Campbell: "Anyways, I will see you again in eight hours. By then, those satellites should already be in space and I'm expecting that you'll receive a complete briefing on all that happened."

Josué: "Alright, John. Take care."

Eight hours later...

25th of April, 11:30

A hundred kilometres to the north of Gibraltar, the Quistadoria Empire's Southern Imperial Army

Covering the land as far as one's eye could see, stood the mighty Southern Imperial Army, consisting of hundreds of thousands of knights, foot soldiers and archers, known to be one of the largest and most experienced armies at the Empire's disposal.

Flying directly above the Southern Imperial Army were several wyverns from the 1st Imperial Wyvern Squadron.

At the head of the columns was the Duke of Nethiolor, Rictiovarus Geberic. A renowned Captain General and a privy council member, he was experienced and wary compared to other Quistadorian generals.

Besides him was his Lieutenant General, Gaiseric Himnerith, an over-confident and, often, reckless commander, he is normally the second-in-command of Rictiovarus, although he was rather worried about Gaiseric's recklessness.

(Author Note: The ranks "Captain General" and "Lieutenant General" were used when armies evolved to formally organised and permanent military forces.)

As the columns continued marching towards Tariq, the Sergeant Major General, Sigmund Retemeris, rushed towards the front in a hurry, trying to reach both Rictiovarus and Gaiseric as fast as he could.

Sigmund: [C] "Lord Nethiolor!"

Rictiovarus: [C] "What's it, Sigmund? Did our knights already come back?"

Sigmund: [C] "Yes, my liege. But..."

Rictiovarus: [C] "But what?"

Sigmund: [C] "Only thirteen managed to come back, my liege. The rest, they said, were annihilated-"

Gaiseric: [C] "That's absurd! All those 350 knights are all veteran knights, there's no way they could've been annihilated by mere peasants!"

Gaiseric interrupted Sigmund before he could finish his words, the news simply didn't make any sense to him. That was until Rictiovarus glared at Gaiseric that Sigmund continued.

Sigmund: [C] "Those knights said they encountered soldiers with strange attires and magic equipment, none of which was anything like they've recognised. The magic equipment released a flash followed by a loud noise and then suddenly, the knights around them fell from their horses, dead."

Sigmund: [C] "Other than that, my liege, the knights said those soldiers were all speaking the "ancient" language."

Rictiovarus: [C] "The ancient language? That should've been impossible nowadays. Sigmund, send a messenger to the capital and inform our Emperor of this immediately."

Sigmund: [C] "Yes, my liege."

Gaiseric: [C] "But how about Tariq?"

Rictiovarus: [C] "Either way, we've come too far to turn back now. We will continue towards Tariq."

Gaiseric: [C] "I was expecting that."

Rictiovarus: [C] "Mind your language, Gaiseric."

Gaiseric: [C] "...My apologies, my liege."

Unbeknownst to both of them and their entire army, their movements were being closely monitored by a single Protector RG Mk 1 MALE UAV and a Recce section from the Royal Gibraltar Regiment...

(Author Note: "MALE UAV" stands for medium-altitude long-endurance unmanned aerial vehicle and "Recce" is the term used by the British Armed Forces for reconnaissance.)

At the same time...

In the conference room, the Pindar, London

Inside the room were senior members of the cabinet as well as senior military officers who are part of the Defence Council of the Franco-British Union.

On one half of the screen were images taken of the new world they found themselves in by the satellites recently launched today. On the other half were live footages sent from the Protector drone that is flying over the Quistadorian Empire's Southern Imperial Army.

(The satellite image of the New World: https://drive.google.com/file/d/1-iQlofbgtM_hJCi4sPHHedHz3PRPk6P3/view?usp=sharing)

(Author Note: Those marked in purple represents the Franco-British Union and its overseas territories which were teleported into the new world, as you can see, the overseas territories are now all around the British Isles and well, that's 1/3 of the whole map, for now.)

Josué: "So other than the fact that there's an army marching towards Gibraltar, we also know almost nothing outside of our borders."

Campbell: "What a strange world we've found ourselves in."

Brian: "Sir, if I may."

The Foreign Secretary, Brian Fallone stood up and walked over to the screen before pointing at the peninsula that resembles the Iberian Peninsula back on Earth and the island that replaced Ireland to the south of Northern Ireland.

Brian: "As far as I am concerned, our priorities should be establishing diplomatic relations with nations outside our borders, sir, as such, I would suggest dispatching one of our carrier strike groups from the Home Fleet, accompanied by officials from the MOD and the FCDO, south to this new peninsula, sir."

(Author Note: "MOD" is the abbreviation for the Ministry of Defence and "FCDO" is the abbreviation for the Foreign, Commonwealth & Development Office).

Josué: "Speaking of that, John, is it true that the entire Pacific Fleet suddenly found themselves outside of Scapa Flow?"

Campbell: "The rumours turned out to be true, Josué. They're now stationed at Scapa Flow for the time being."

Josué: "I see. What do you think about Brian's suggestions, McCarthy?"

McCarthy: "We can dispatch HMS Ark Royal and her carrier strike group immediately, Prime Minister. Although we will have to arrange preparations for the MOD and FCDO officials too."

(Author Note: In this timeline, because of the FBU's status as a superpower, they have six Queen Elizabeth-class aircraft carriers, the HMS Queen Elizabeth, HMS Prince of Wales, HMS Charles de Gaulle, HMS Richelieu, HMS Ark Royal and lastly, HMS Foch.)

The First Sea Lord Admiral Thomas McCarthy nodded in agreement to the Foreign Secretary and the Prime Minister.

Josué: "Very well then, we'll dispatch HMS Ark Royal and her CSG from Brest. The rest is up to you, McCarthy."

McCarthy: "Understood, Prime Minister."

Josué: "Campbell, place the Home Fleet, the Mediterranean Fleet, the 3 Commando Brigade, the 16 Air Assault Brigade and the units stationed at Gibraltar at AMBER state. I will handle the press myself."

(Author Note: Similar to the five DEFCON levels, the UK also have a similar system called the BIKINI state which is RED, AMBER, BLACK SPECIAL, BLACK and WHITE. AMBER in this case mean "high alert" which could transition to war, similar to DEFCON 2 and 3.)

Campbell: "Very well-"

Before the admiral could finish his words, however, the prime minister's advisors rushed into the room with reports of an unknown creature in the North Sea sighted by HMS Queen Elizabeth and her carrier strike group. And suddenly, the room was thrown into chaos once again...
