Well, it took forever, but here it is. I made it extra long to make up for the long wait. Go ahead and message me if you have any suggestions.

Regrets

Fionna spread out her arms on her bed, her legs still in the sleeping bag. She looked over at Cake, who was sleeping in the wardrobe drawer.

She checked the clock again. 10:14 p.m.

When they had finished their lunch date at Pizza Sassy's, Marshall had said that he would come over later. Later... What did he mean? Tonight? Tomorrow? Ugh... The frusteration was really getting to her.

They had been together for almost a week now.

She heard a knocking at the door and shot up. She fell onto the floor trying to get out of bed, getting back up and getting down the ladders as fast as possible. When she opened the door, it was not Marshall she saw, but Prince Gumball was there instead.

"PG? What's going on?" She said, surprised.

"We need to talk." He started laughing and almost fell over. Fionna could smell the alcohol on his breath.

"PG, are you, are you drunk?" Fionna asked.

"No! You're drinked!" He slurred. "How could you do this to me?"

Fionna looked at him, disbelief on her face. "Why don't you come inside? We can you some coffee, and call Peppermint Maid," Fionna droned on as she led him up the ladder, surprised that he didn't fall off.

Fionna made some coffee and gave it to Gumball, moving over to the living room and finding the radio headset. She called Peppermint Maid, explaining the situation.

"I'm sorry about this Fionna. I'll be over as soon as I can."

"Thanks PM." Fionna set down the headset on the coffee table and went to the kitchen to check on Gumball.

"You doing alright?" Fionna asked, sitting next to him.

"Yea. Thanks."

"How much did you have to drink?"

"A shot of tequila." He said shamefully.

Fionna waited for an 'and', but it never came. "One?"

"Yea..."

"One? One shot? You got wasted from one shot of tequila?"

"Damn. Now that's just sad." A voice came from behind them.

"Marshall!" Fionna said.

"Hey, Fionna." He glided over to the table and kissed her on the cheek. "So what's with Gumwad?"

"He can't hold his liquor." Fionna could see Marshall's anger through small things. That blink away from her gaze, keeping his hand possessively on her shoulder, it all summed up to one thing: 'What the hell is Gumball doing here?'

Trying to brush it off, Fionna turned back to Gumball. "So you said you wanted to talk. What's that about?"

"Oh, that, um..." Gumball rambled off, trying to explain himself. "That, it's, it's nothing."

"It's not nothing. Spill it."

"It's nothing!" Gumball said forcefully.

"Listen, Gumwad!" Marshall was beyond angry. "You can't just come over here wasted and-"

A pounding on the door cut Marshall off.

"That'll be Peppermint Maid, no doubt." Gumball said relieved, happy with the excuse to leave.

"Gumball!" Fionna called after him angrily, causing him to look back. "We're going to talk about this."

"We just did." He said as he climbed down the ladder.

When they heard the door close, Marshall groaned in frustration. "What is his deal? Why does he have to be such a-"

"Gumwad?" Fionna finished for him. She thought back to what Gumball had said.

The last time she had talked to Gumball, he had seemed fine. When she confronted him before her first date with Marshall, he had seemed fine. Completely fine with Fionna halting any romantic relationship they would ever have. And yet, a shred of doubt wormed its way into her mind.

"Exactly." Marshall lowered himself to the floor in front of her, wrapping both arms around her waist. He kissed her and she felt the heat of his breath in her mouth. "But let's not let him ruin our evening. I wanted to show you something super banaynays."

Fionna took his hand and climbed onto him piggy-back style. He flew up through the open window, sailing over the grasslands. They flew for what must have been hours, finally arriving in the mountains. Landing on a ridge with a steep drop behind it, they made their way to a hole in the stone.

"Come on." Marshall said, siting at the entrance and sliding down. Fionna followed after him, and he caught her at the bottom.

"Wow." She breathed, looking around the cavern. The walls were made of what looked like crystals, pulsing energy flowing through them, never a single focused color. But what amazed Fionna the most was a large spectral portal at the back of the cave, a glowing green.

"What is it?" She asked in wonder.

"This is the last untainted portal to the Nightosphere. Before my mom can claim a portal, she has to find it. And they're invisible in the Nightosphere."

"Woah. That's deep shit." Fionna said.

"Yea." Marshall looked over ar her. "Would you like to come in there with me?"

"Is it safe?" She asked, a look of worry on her face.

"Yea. It'll take you anywhere in the Nightosphere you want to go. And there are some places that my mom can't even stand." Seeing Fionna's unceasing concern, he started to walk towards it, sticking his arm through. "Come on." He stretched out his other arm for her to take.

Taking a leap of faith, she grasped his hand and was pulled through the portal. She could feel the liquid of the dementional void around her. She held her breath, inhaling only when Marshall pulled her through to the other side, into the realm of darkness.

"Welcome to the Nightosphere, Fionna. My name is High Lord Marshall Lee, King of the Vampires and heir to the throne of the Demonic realms, and I will be your guide this evening."

Fionna looked around her. They were in a large Gothic-style mansion, a massive chandelier made of crystallized demon blood suspended over them. A grand staircase was in front of them, leading to hallways that no doubt had hundreds of rooms. Light filtered in through stain-glass windows that lined the tops of the high walls. "Where are we?"

"My wing of the palace. It's not much, but it's mine..." Marshall remarked nonchalantly.

"Not much? Marshall, this is amazing!"

"Would you like the grand tour?"

Fionna could only nod and Marshall picked her up again, flying through each room.

"Here we have the dining room, the game room, the library, the kitchen, war strategy room, treasury room, aviary, combat room, pool, this hallway is entirely full of guest bedrooms, and here," he said, finally raking a breath and stopping to set Fionna down. "Is the master bedroom."

Fionna pushed open the double doors, gasping at the impressive room, easily the size of the tree house. There was a gigantic four-post bed with red and gold blankets, dark wood furniture lining the walls. "Beautiful…" she said in amazement. She moved to the center of the room, looking all around her.

"I agree wholeheartedly." Marshall said, staring at Fionna, who blushed, wrapping her arms around his neck. She kissed him softly, interrupted only by a slow clapping from the edge of the room.

The doors slammed closed behind them the workings of two sinister looking demons, and Hannah Aberdeer strolled across the room. "Bravo, bravo." A gruesome grin was plastered across her face. "Now, that was much too easy."

"Mom!" Marshall yelled, teeth bared. Fionna reached behind her, pulling out her sword made of demon blood.

"Oh, not very friendly, I see." She sat down in an elegant red chair. She snapped her fingers, and the two demons grabbed Fionna and Marshall from behind. A clawed hand clamped over Fionna's mouth, muffling her angry screams.

"Now Marshall, I wish to have a pleasant conversation with my son about his future. Is that really so much to ask?" Hannah said, examining her nails.

"It is when it involves you forcing me to give up my soul!" Marshall tried to scream, the demon's hold tightening around his chest.

"Oh that silly thing? I must tell you, everything's much better without it. Now stop squirming, I'd hate for anything to happen to your little friend." The demon holding Fionna pressed a claw into her neck, burning her skin and making her scream in agony.

"Stop!" Marshall yelled in protest.

"More than a friend?" Hannah guessed, seeing the pain in her son's eyes. His thrashing confirmed her theory. "Ah, well, I think I may have overlooked one of the inheritance laws. Because you are giving up your soul, and you have found yourself a," Hannah paused, casting a long glance at Fionna. "Mate, you are able to retain your soul until you produce a living heir." She smiled cruelly. Hannah snapped her fingers, and the demons released the young couple.

"You sicken me." Marshall said in disgust, examing the burn and bruises on Fionna's neck.

Hannah chuckled. "Of course, no law says I can't keep you here until such an heir is produced. And I would get started. Even humans can't survive long here without food."

"You're a monster." Marshall said, hugging Fionna to him, the demonic burn sapping away at her strength and leaving her barely conscious.

"And you're a monster's son." Hannah called, leaving the room.

Marshall and Fionna spent almost a week in the room. Marshall had managed to get his point across that if Fionna didn't get food, she would die. He also convinced his mother to give Fionna time to heal.

"How are you feeling?" Marshall asked one morning, stroking the hair on her forehead.

"Better." She replied weakly. The burn on her neck now took on a welt-like form, bright red and hot to the touch.

"Well enough to try to escape?" He whispered softly in her ear. She looked into his eyes and nodded. "Great. Now all we need is a plan."

Jeff, the demon posted outside the door, wasn't the brightest demon at Hannah's disposal, but she needed everyone else for her plans. His job was simple. Stand outside the door, don't let anyone in, and don't take down the energy barrier that blocked Prince Marshall Lee and the human girl inside. Everything was fine for Jeff until the skeleton man showed up.

The skeleton didn't say anything, just handed Jeff a scroll of paper. It took Jeff a moment, but he read it through.

"Release the prisoners? Why?" The skeleton just shrugged, and his body merely melted into the floor.

Jeff didn't want to anger Ms. Aberdeer, because he knew from personal experience what happened. Jeff touched the energy field, wadding it into a tight ball. He opened the door, peeking in.

"Ms. Aberdeer says that you're supposed to be released." Jeff said, Marshall going through the door and helping Fionna walk.

"Thank you Jeff, now keep guarding the door. I have a feeling that you might have a promotion coming." Marshall said.

Jeff smiled and resumed his post in front of the door, not suspicious at all.

Marshall helped Fionna down the hallway, glancing into the main hall. "Okay, we just have to get through the portal and back to Aaa without being seen." He looked around, trying to find a guard, an alarm, something. Helping Fionna down the stairs, Marshall looked around constantly, waiting for something. Something was off.

The two of then tot right next to the portal, ready to leave. But with a flash of red and a fleshy rip, their hope was cut short. Marshall heard Fionna gasp, and he turned back to her. A long shard of demon blood, well over a foot long, was sticking out of her chest.

She looked to Marshall, who was frozen with shock and fear. A horrible laughter came from above them, nestled in the chandelier. Fionna coughed, blood covering her shaking hand. Marshall tried to pull out the spike before the damage could be done, but Hannah landed between them, pushing Marshall to the ground. Hannah grabbed the blade, twisting it. Blood began to pour out of Fionna's chest. Fionna began to scream as the demon blood liquefied in her body, searing all the flesh around the wound with a sharp sizzle.

Marshall tried to reach for his lover, to try to save her, but Hannah grabbed him by the neck. "You had your chance. Now she's mine. She's your mate, and she can take the throne if you won't." Hannah threw Marshall through the portal, sealing it. She turned back to Fionna, the girl bent over, hiding herself. Hannah rested her hand on the girl's shoulder, smiling at her. Fionna looked back at Hannah, and knelt before her.

"Rise, my child." Hannah said. "You are whole without a soul, and you will rule our people well."

Fionna looked at her with red eyes. "Yes, mother."

Don't be mad at me! I'm going to make a sequel, and if you review or message me, I'll only be able to make it better.
