A week before the events.

It was strong storm in the Land of Ooo. It was raining hard, lightnings flashed and the roaring thunder could be heard. It was the worst time to go outside warm houses.

Suddenly red lighting flashed, leaving a small crater where it hit. When dust disappeared, it revealed a man inside crater. He was tall, thin, he had very short black hair and grey skin. He wore black cargo pants with two holsters with pistols inside, dark-gray T-shirt and long black leather coat, which reached his combat boots.

The man slowly stood up, revealing his demonic-looking, fully red, sick eyes. The man coughs, leaving some blood on the ground.

"Well, now I am here", - the man said in dark, emotionless voice. "But before I will do my deals, I must find myself some... allies."

He has raised his hand, and a red lighting came from it, hit the sky and turned some of it's area in red color.

Nowadays.

It was already morning, so Finn, Jake and Marceline were in the truck, driving to Bad Lands. They were near it, the red sky was directly above them. Each and every one of the three were on guard. They are ready to shoot, if necessary. But they hope nothing will happen.

Suddenly the truck has stopped. "Final destination reached. Awaiting further commands." inscription appeared on screen. Marceline turned the engine off and went outside, along with the others.

They stepped on a dark, lifeless earth. It is all in cracks, as if it is dry.

—Guys, look at this place... Ready your guns, I feel something evil.

—We're ready, Marceline! - Finn and Jake responded.

They were slowly making their way to the centre of this lifeless place. There were no sounds, except for their footsteps. Everyone were feeling nervous, ready to open fire at any second. Suddenly a red lightning flashed and thunder came. Everyone winced, then noticed a man on top of a small hill.

He has nothing in his hands, which were crossed on his chest. But all guns of our heroes were aiming right at the man.

Man: "Well, hello there. Welcome to my residence."

M: "Who are you? What are you doing here? Have you done it with the sky?"

Man: "I am someone you've never heard about. I do not recall my name, so you can simply call me Red-Eyed, I think you understand why."

F: "You will pay for turning sky into red and for scaring people!"

R-E: "You all better leave, or it will be worse."

J: "No way man, it will be worse for you, if you don't give up and go with us, weirdo!"

R-E: "Well, you've chosen the bad way."

As he spoke it, he raised both of his hands and formed a red flame out of it, which formed a circle around three heroes. The circle disappeared five seconds later, revealing lots of skeletons with spears and swords, which are ready to attack Finn, Jake and Marceline.

Skeletons started rushing towards the three, who have already opened fire. Marceline were shooting in short burst, about three-four shots to one skeleton. Finn turned fully-automatic mode on and shoots at everything he sees running. Jake was firing in semi-automatic mode, one shot - one deadly dead skeleton.

First wave of skeletons were shot in a matter of seconds, but there were no cartridges in the clips of our heroes by then. Finn pulled out his Finn-sword, Jake made himself big, and Marceline grabbed branch, which were lying alone on the dry ground.

Finn showed his excellent swordmanship, cutting most skeletons in two and more pieces, stabbing through their weak bones and cutting their heads off. Jake was punching skeletons with no mercy, and Marceline swung her branch left and right, hitting almost every skeleton in her reach.

Second wave of skeletons were ended in a minute, so everybody was panting and sweating. Red-Eyed just stood upon a hill, looking at the three.

F: "As Jake has said...*Pant*...Give up!...*Pant*"

R-E: "*ignoring Finn's demand* I challenge you to a duel! As I can see you have excellent swordmanship. So, these are the rules of my duel: first, no one else interrupts. Second - there is no other rules."

Red-Eyed formed a red-bladed sword in his left hand and stood in a fighting position. Finn stood in a fighting position too. The fight has begun.

Swing - dodje. Another swing - block. Thrust - dodje. Multiple swings - all blocked.

R-E: "*dark laugh*"

Swing - block. Another swing - block. Yet another swing - dodje. Two thrusts- blocked.

Suddenly Marceline threw a stone in the man, who easily deflected it with his sword, sending it flying towards Finn's head. Finn screamed and fell, loosing his sword. The man has pointed the sharp end of his sword at the Finn's neck.

R-E: "Rule breaking from your friend will not be tolerated."

He raised his sword over Finn, ready to strike. So he did, but missed - Finn rolled, then kicked the man. He has fell, while Finn obtained his sword back and was ready to strike down the man, when suddenly a red light came from man's hand and pushed Finn, making him fly some meters before reaching the ground with his back.

R-E: "Ego interfici non possunt."

Suddenly Red-Eyed appeared in front of Marceline and pushed his sword through her chest. Jake and Finn were screaming "NOOOOOOOOOOOOOO!" as she fell down on her knees.

Finn rushed to the man, kicked him, sending him flying, grabbed man's sword, ran to the fallen man and stabbed his chest, while he almost stood up. The man put his hands on the hilt of his own sword, trying to take it out of his chest, but he died. His eyes changed to the black, he fell on the ground, letting go the hilt of sword, still with his own sword in the chest.

Finn ran to Marceline and picked her up.

F: "Marceline, are you okay? Can you hear me? Please don't die, Marcy!"

M: "*coughs, weak voice* Just let's get out of here..."

F: "Jake, get the truck ready!"

J: "I'll do it!"

Finn carefully took Marceline to a truck and put her down on the floor, putting some cloth on the floor before. Jake turned on the engine and ordered truck to go to next destination - Candy Kingdom, Candy Hospital.
