Whooo, almost five pages! Hope you guys like~

The two friends dragged Danny into the nurse's office, telling her that he was burning up. The nurse frown in concern when she realized that they were right; his fever was high, even with him being normally under the regular. She called Maddie and told her to pick up her sick son. Afterward, much to Sam's and Tucker's disappointment, she sent them back to class. Danny was left lying on the cot until his mother came.

He felt horrible, and he felt worse knowing that his powers seemed to be offline. What if it had been Skulker or something else of the likes? Someone could have gotten really hurt! He rolled over, feeling both mentally and physically sick. If he had been able to go ghost, then he would know that he was just sick with a flu. However, he couldn't. Something was wrong and he couldn't go ghost. He rolled over, face into the pillow that smelled as if it had a date with sterile itself. Eventually, he fell asleep and didn't wake until his mother rubbed his shoulder. She took him home, where Danny continue to sleep until evening.

He woke up to his cell phone ringing on his nightstand. Still groggy from sleeping, he opened the cell phone to answer. "Hello?" he said, his voice husky.

"Man, you sound terrible. Anyways, Sam and I were thinking of checking out the ghost zone. You know, in case there's something going on? Cause sick or not, you should have gone ghost just fine . . . Hey, are you still there?" Tucker asked the last part after a period of silence.

"Yeah, sorry," Danny grumbled. "Sure, sounds good. I'll come with you."

"You sure? Cause you sound-"

"Yeah, I know. Dead. Yes, I'm sure."

Danny could practically hear the shrug that Tucker did afterward. "Fine, then, dude. Your call. We'll be there at ten tomorrow, okay?"

Danny made an affirmative noise before hanging up. He walked down stairs to find some food, however his stomach quickly complained. Grabbing a few crackers, he went back upstairs into his bed.

The next day, Sam and Tucker was at Danny's house at the designated time. They both cringed at how horrible Danny looked. He was almost paler than Phantom himself, and the dark, long sleeve shirt he was wearing didn't helped. However, they let it pass and instead walked to the basement. Opening the portal and getting into the handy machine that Jack Fenton had made, they started their journey through the Ghost Realm.

Danny tried again to go ghost, but nothing happened. He sighed heavily in annoyance, trying to ignore the worm of fear in the back of his mind. Sam and Tucker were full human and they were fine, so he should be, too. Right? He glanced around, outside of the windows. The Realm was always super creepy. It was as if it was a horror movie. And it seemed worse when you weren't a ghost. After a while, he squeezed his eyes closed, the fever causing him to get dizzy and nausea. There was nothing in the ship that he could be sick in, so he tried his best to keep it in.

He almost lost it when the whole ship lurched to the right. He groaned at his stomach that was doing flips. "What happened to smooth driving?" he muttered. He heard Sam curse under her breathe, so he decided to open his eyes and see what she was cursing at. Surely, she wasn't cursing at him. Looking around, he saw a huge ghost flying, crashing into the ship on purpose. For some reason, this ghost seemed more aggressive than any of what Danny had seen. It was purposely trying to destroy their ship.

"Hang on!" Sam shouted as she swerved around. Tucker was gripping the door, almost as pale as Danny, and Danny was keeping his eye closed. After a moment, she finally sighed and started driving more smoothly. Danny opened his eyes and looked around. It seemed like the ghost had gone away, probably looking for an easier prey. Tucker glanced back at it. "Note to self," he muttered to himself, "don't ever go through there again." The two other friends nodded in agreement.

The continue flying through the realm, looking for anything. For a sign, maybe. After about five minutes, they found a huge sign that read: LIBRARY. The three looked at each other before shrugging their shoulders and parking the ship. Who knows, maybe what they need is through there? They got out and floated to the door and through it after opening it. True to it's name, it was indeed a huge library, filled with books to the roof. Or, if it had one. The trio looked up at the shelves. It went way up to the point that they couldn't see where it ended. Danny's stomach lurched when he thought about if a book fell on them. He had no doubts that it'd hurt.

He looked at the books, trying to figure out what they were about. Some books were so old, the binders were worn thin and the words indecipherable. Some books were in an odd, old language that Danny has never seen before. And some, much to his amusement, was fictional books from Earth, such as The Ranger's Apprentice and Deltora's Quest. He wondered curiously if all of these books were fiction or if some had any truth in it.

The door slammed shut, scaring the trio. They turned around to looked at the closed door. Standing in front of the door was a ghost of a man, extremely old. If Danny had to guess, he'd say he was at least a hundred. He even had the classic, long, beard. He looked like one of those cartoon magician. The three looked at each other, not knowing what to do. The old man didn't say a word, he just stood there and watched them.

"Uhm, sir? Could you, maybe, help us?" Tucker asked, hesitantly, while trying to be in his best manners. They had no idea if this ghost was nice or not so they didn't want to anger it. Instead of answering them, the old ghost simply point his index finger to the space behind the three friends. They looked curiously, wondering if he was pointing to something. They watched in awe as a book, covered in a green aura, floated over to them. When Sam reached to it and grabbed it, the aura disappeared and the book fell into her hands. Unfortunately, she didn't realized just how heavy it was and almost dropped it. Danny glanced up at the ghost and thanked him. He just got a scoffed instead and the old ghost vanished.

They opened the book to reveal many pages in the old language that Danny had seen earlier. They stared blankly at it, flipping pages to find some sort of sign that told them what it said. After a few moments of flipping, Danny saw something that caught his eye. "Wait!" he called out, shoving his hand between pages. They flipped back to that spot. One of the pages was an old painting of a ghost, the exact type that Danny had tried to fight the other day ago. For some odd reason, this page was in English.

"It's called a Lillerian," Sam read. "An uncommon ghost that appears in what seems to be every other hundred of years. It's a ghost of poison-"

What does that mean?" Tucker ask, interrupting Sam. She glared at him.

"I could tell you if you let me read," she snapped back at him.

"Sorry," he replied, sheepishly.

"Now where was I? Right. It's a ghost of poison, meaning that it's poison to anything and everything around it. That is how this creature gets it's strength: it sucks the life out of anything around it. It affects ghosts more than humans, often causing the ghosts to disappear."

Danny did not like the feeling of that. Neither did he like the feeling of his stomach flopping.

"With humans, they often appear as to be getting sick and dying from that rather than ghost itself. As of yet, there are no cures except to get rid of the ghost. It has a cage that it is kept locked in," she finished reading. She continued scanning the pages some more before sitting it down.

"So, what does that mean?" Tucker asked, hoping he was wrong. Sam looked at Danny, concern and worry evident in her purple eyes.

"It means Danny's dying."

Danny shuddered. He didn't felt like he was dying. He just felt miserably sick. He had suffered through half-dying, and that itself was painful. But this felt nothing like it. Maybe it's because this isn't a natural death, he thought to himself. He shivered, not liking where his thoughts were going. Ending the thought train, he looked back to Sam. "So it must have escape from this cage. We catch it, turn it back, I'll be better?"

Sam shook her head. "I have no idea, but let's hope so."

Tucker laughed nervously. "Okay, then. Let's do this. Team Phantom again?"

Danny frowned. "Not team Phantom, team Fenton. I can't change into Phantom. I think that Liller-something did something to it."

"Lillerian," Sam piped in, helpfully.

"Whatever. Anyways, it's all I got right now, so let's hope we can do this with Dad's tools," Danny finished, looking wryly at Sam's and Tucker's ghost stuff that managed to sneak from Jack. Danny hasn't had the chance to use it as much as them so he wasn't all that sure. He wondered absently if it would still shock him or not now that Phantom's out of commission.

The group left the Library and got into the Fenton machine and started their journey back home. At one point, Danny had looked back to see if the entrance was still there. He got the creeps when it wasn't, and he turned around to look away. The whole ride, Danny kept his eyes closed. He wanted to keep the nausea at bay, but he also wanted to get some shut eye during the ride; he felt exhausted.

However, it seemed as if the universe did not want poor Danny to get some shut eye. The same huge ghost was back again and was bashing itself against the ship. This time, Tucker started pressing buttons in hopes that something will happened, hopefully something that would help them. A laser gun came out and shot the ghost. It let out a huge roar in pain, lashing out again at the ship, Danny groaning at the movement. After a few more shots, though, the ghost finally retreated and left them alone. They exit back into the Fenton' basement, the portal closing behind them. Danny quickly climbed over them and out, running to the nearest trash, and empty what little there was in his stomach. Sam made a sympathetic noise while Tucker himself tried not to be sick while watching Danny. Sam walked over to him and kindly rubbed his back as he heaved, nothing but acid in his stomach.

"I feel awful," Danny managed to speak between heaves.

"You look awful," Tucker shot out, however Sam's glare shut him up before he continued on that thought.

Finally Danny's stomach calmed down enough for him to separate from the trashcan. The three crept upstairs, sneaking past the Fenton's. They were not in the mood to explain where they had gone through the Ghost Portal. They gathered in Danny's room, shutting the door behind them. Danny laid down on his bed, sighing in relief, while Tucker sat on the floor. Sam took his computer seat, planning on doing some research.

"I looked at the page about the Lillerian and it talked about where it likes to gather. And typically to every monster there are, it likes to hide in dirty places."

"Like Tucker's socks?" Danny teased, a hey following from an offended Tucker.

"No, worse. The dumpster."

"Aw, man! Does that mean we have to go through a freakin' dumpster to find this Lillerian thing?" Tucker asked, a horrified expression on his face.

"Yep," Sam replied, popping the P. She turned around to Danny's computer and started looking up where dumps were in the town. After a few minutes, she turned around back to the boys. "Looks like there's three in total. We should look at them and see if we can find it. Danny can't defend himself as good, so we all three have to work together. It means that it'll take longer, but will be safer."

"Uh, Sam?"

"What, Tucker?"

"Danny's asleep," Tucker informed, pointing to the silently snoring form of Danny. He had fallen asleep as they talked. She sighed and shook her head. They silently agreed to let Danny sleep and crept out of his room. They didn't needed to ask twice; Danny looked terrible. He almost seemed worse than he did yesterday.

Sam walked to the living room where Jazz was sitting, drinking some milk while reading one of her colleges books. She looked up at Sam, raising an eyebrow at her curiously. "Where's Danny?"

"Sleeping. Let him know that we'll be here at eleven tomorrow, okay?" Sam asked while putting her coat on to leave.

Jazz watch them leave, her eyebrow still raised. "Okay?" she said, wondering what on Earth was her little brother up to now.
