Hey there everybody! I'm back! Geez it's been like 10 months. Sorry for being gone so long. Well anyway, I'm going to finish this story (I promise) and begin working on other projects. I don't know how many chapters I plan on doing. I'll just keep writing and see where it goes. I actually already envisioned two paths for this story to go, but I don't know which one I should pick. The story is going to get more serious as it goes on (This is rated T for a reason) but I'll try to keep the Adventure Time humor going. This is supposed to become and epic adventure. Also I'm really bad at writing romance so…we'll see how that goes. Now, on to the story!

"So that thing is headed here PB?"

"I'm afraid so Finn..." She deeply hoped he'd grasped the severity of the situation.

"Hmm...then it sounds like it's," He raised his hands into the air, a goofy grin on his face. "ADVENTURE TIME! I'll grab Jake and we'll take care of it! Don't you worry princess!"

"Finn!" She was completely flabbergasted. "This isn't a joke! This is a huge threat! Bigger than anything you've ever had to face before! You have to be serious!" Had he even listened to a word she'd said? How could he treat this like another one of his little adventures with Jake?

"Finn," she exhaled, trying to stay calm. "The future of the Candy Kingdom, no, all of Ooo is at stake! You have to take this seriously. Think of all the lives that will be lost if you fail. You can't just go rushing into this. You have to be prepared."

"How, Peebles?"

He still looked like he wasn't even close to being concerned like Princess Bubblegum thought he should be. However, she hadn't thought of that. In fact she failed to even think of a plan of action yet. She was too busy being worried to think rationally.

"I'm going to have to do some more research on that," she mused. "In the meantime, tell Jake about the situation, and start getting prepared." She knew Finn wasn't strong enough to deal with the monster. Finn walked off, and with that she began to make her way to her personal library. She just hoped Finn wouldn't go and do anything…rash.

...

"That sounds pretty serious dude." Finn had arrived back at the tree house and relayed everything Princess Bubblegum told him to Jake.

"Aww, c'mon Jake! How tough can this guy be? So he's destroyed a few kingdoms. Psh, whatever! We've faced worse before right? Remember the nasty old Lich King?"

"Yeah I remember."

"Didn't we eventually kick his butt?"

"Yeah man."

"Remember when we went inside Beemo and beat that crazy hard game?"

"Yeah…"

"And not even to mention the dozens of times we kicked Ice King's creapy butt."

"I just don't know man," Jake looked fearful. "Barf. Maybe PB is right! Maybe we should just wait a while and make a plan."

Didn't Jake understand? "The longer we wait the more people are going to die Jake. If we're gonna fight this guy we need to hit him now and hard." If Finn was going to do this he knew he needed his right hand man with him.

Jake thought about it. "I guess you have a point brother. But we don't even know where this guy is at." Good point.

"PB told me she got the letter from Far Away Princess and that the monster was headed to the Candy Kingdom. That's to the northeast. We just need to go in that general direction right?"

"Sounds about right to me," agreed Jake. "Let's head out now. Like you said, the faster we take care of this guy the better."

Finn was confident in himself. Sure he'd faced some tough trials in Ooo, but he always triumphed in the end. He was sure this time would be the same. Princess Bubblegum had nothing to worry about. She'd see.

~Later – Night time~

Princess Bubblegum had spent the entire day pouring over the immense number of books in her library, desperately searching for anything that would help Finn in his quest.

"Why did he have to be so headstrong?" She wondered. She just knew in her heart one day his stubbornness would get him in trouble if he wasn't careful. She then imagined Finn dying at the hands of the monster. "No! I can't think like that." She pushed the negative thoughts out of her head and regained her composure. She was determined to find the information she so desperately needed. Finn was counting on her. All of Ooo was counting on her.

Hours into the night later she finally found was she was looking for.

"Long ago, after the 20 heroes sealed the great monster away, they pooled their power together, and locked it away in sword. They placed this sword in a secret cave somewhere in Ooo, so that in case the monster ever escaped its bonds, a new hero would arise and take the sword to slay the monster again."

"This is it!" she exclaimed. She called for Peppermint Butler.

"Yes, your majesty?"

"Send word to Finn and Jake at once! Tell them I have urgent news for the both of them."

"Right away your majesty."

"Finally," she thought. "Now we may actually stand a chance. But who knows where this cave could be? Ooo is incredibly vast…Only someone who's been alive an immense amount of time could possibly know its location..." She ruminated on the new information.

She begin to pace her study, waiting for Finn and Jake to make their much needed arrival.

...

Marceline was lying on her bed when she heard a knock at her door.

"Finn? At this hour? That's unusual…"

"Coming!" She yelled. As she made her way to the door she wondered what Finn could want from her in the middle of night. She opened the door and instead found Princess Bubblegum staring at her.

"Bonnibel…it's been a long time since you've come here like this," she said with an undertone of absolute loathing. "What do you want?"

"Marceline...I need your help. It's Finn."

Phew. Writer's block is a horrible thing. Well what did you think? Leave me a review and tell me how I'm doing. Sorry this chapter is a little short, but a lot of things happened and I needed to actually get the story moving. I hope I'm portraying the characters right. Keep in mind I haven't seen season 3 in its entirety so I'm going off of what I've seen. Criticism is welcome. Until next time!
