Bad Memories

Finn opened his eyes looking around. He was in the same void as where he had met the silhouette in his last dream. There was no smoke this time, but there was a silhouette. It stood before him, eyes glowing red, blood running out of them and down its dark face, dripping to whatever they were standing on.

"Who are you?" Finn demanded, trying to fight back the fear gripping his heart.

"It would seem my servant disobeyed me," the silhouette said. "No matter. So long as he's not dumb enough to kill you, I'm still able to use you."

"What do you want with me?" Finn growled.

"I will be using you to find the half-blood bitch," the silhouette said. "She is the key. And you, are a useful tool for gaining her blood."

"I'm not letting you hurt Marceline," Finn growled, sprinting forward, forming the Grass Sword and slashing at the silhouette.

He caught Finn by the forearm, grinning and revealing his pointed teeth. Then, he spun, hurling Finn. Finn flipped, crashing into the ground and sending crack spiderwebbing across it. Finn groaned. He was strong. But he hadn't allowed Finn to pass through him. Which meant he could be harmed this time.

Finn stood, sprinting at the silhouette. The silhouette caught his arm again, flipping Finn over his head then slamming him down, cracking the ground still further before kicking Finn, launching him. Finn rolled to a stop and pushed himself up as blood began to bubble up from the cracks.

"So he's begun has he?" the silhouette mused. "Very well. I'll see you soon, Human."

Then, the ground below Finn shattered and Finn fell, instantly being sucked into the blood. He tried to swim back to the surface just as a giant black tentacle wrapped around him. His eyes widened and he looked down, seeing Marceline in her massive tentacle form.

"Marcy?" Finn asked, before covering his mouth, only to realize he could still breathe.

More tentacles wrapped around him, binding his arms and legs to his sides, beginning to squeeze, slowly crushing him. Still more wrapped around him. Around his throat, his eyes, finally his mouth and nose. He couldn't breathe. He couldn't see. Panic gripped him. He began to jerk and kick, trying desperately to get free.

Marcy please stop! Finn thought.

His right arm transformed into a grass whip, pushing the tentacles off and freeing him before turning back into his arm. He looked down at her, seeing her glowing red eyes watching him, the blood around him coming from her mouth.

"Marcy, stop!" Finn pleaded as her tentacles reached for him again and he extended his Grass Sword. "I said stop!"

He slashed, and for a split second, he wasn't there. He was in the Candy Kingdom, staring at a man in a red cloak with transparent red clouds of magic extending from his sleeves to Finn. Finn's Grass Sword was mid-swing, tearing through his cloak. Then, Finn was back, Marceline's tentacles around him again.

"This is a dream," Finn breathed. "The Nightmare Wizard. I have to stop him.

He tried to move but the tentacles held him tight.

"Give up Hero," Marceline's voice taunted. "I'm going to enjoy drinking your blood."

"No," Finn growled. "You won't."

Finn's arm turned into a whip again, freeing Finn just before he was in the Candy Castle. The princesses were closing in on him, blood pouring down their faces from their empty eye sockets. Finn extended his Grass Sword, slashing them, killing them all. Blood poured out of their wounds. Finn ignored it, looking around. He was in control. He had to be in control. He closed his eyes, focusing, and stabbed. He was in the Candy Kingdom, blood was running down his blade. He was at Marceline's house. Marceline was handing upside down from a large wooden cross, screaming in agony, a wooden stake through each hand and foot and the sun slowly rising, the light hitting her feet and slowly moving up, burning her.

"Marcy!" Finn shrieked, trying to run to her aid.

But he couldn't move. He looked down. Hands made of blood were sticking out of the ground, grabbing his legs, keeping him trapped. The sun had reached Marceline's waist. She stared at him, screaming as tears flooded out of her eyes.

"Finn!" Marceline shrieked. "Please! Help me!"

Finn slashed at the hands. Something hit his back. He looked back but there was nothing there. He blinked, slashing them again. Nothing. He looked up. The cross was there, but Marceline was gone. He closed his eyes. When he opened them again, he was lying on his back in the candy kingdom. The Ice King was beside him and the clouds overhead was blood red. Blood was raining from the sky. Finn stood. He pinched himself. It was real. He could see the Nightmare Wizard on a hill in the distance. He sprinted out of the gate and after him. The two banana guards were asleep as well now. As he neared the Nightmare Wizard, the wizard turned back toward him, narrowing his eyes.

"You woke up sooner than I thought," the Nightmare Wizard growled.

Blood was pouring out of a stab wound in his shoulder and a cut on his side. Finn's vision blurred, his heart rate and breathing both quickening. He was terrified, and the Nightmare Wizard knew it. He snorted in amusement, beginning forward, a sword forming in his hand out of blood mixed with his magic.

"What's wrong Finn?" the Nightmare Wizard asked. "Scared?"

He chuckled, tentacles reaching out of his sleeves, a wolf's snout out of his hood, blood dripping from his teeth. Finn stepped backward and fell, beginning to scramble away. His vision blurred further.

"Too easy," the Nightmare Wizard stated. "I'll leave you on the brink of death, and let the Master deal with you."

He raised his sword. Finn's right arm exploded into a massive grass spike, impaling the Nightmare Wizard through the chest. The Nightmare Wizard froze, sword fading and his tentacles and snout disappearing. As they did, Finn's fear evaporated, leaving him mostly calm.

"What...are...you?" the Nightmare Wizard growled.

"My arm kind of has a mind of its own," Finn stated, smiling at it. "Guess it likes having me around."

The Nightmare Wizard leaned forward, then began to cackle.

"What's so funny?" Finn asked.

"You're too late," the Wizard laughed. "You can't stop the summoning now. He's already here."

"He?" Finn asked, the silhouette flashing through his head. "Oh no."

The Nightmare Wizard laughed again but it was cut short as he coughed, blood splattering on the ground before the Grass Spike retracted, turning back into Finn's arm with the Grass Sword. The Nightmare Wizard collapsed just as a massive geyser of blood shot into the sky and fear once again gripped Finn as the voice reached his ears.

"Ah at last. Shall we begin?"
