The three Slytherin demigods are Jackson, Malfoy and Nico by the way, I know Nico technically isn't a Slytherin but he likes sitting over there. And Percy's, Neville's, and Luna's cups were poisoned too, they just hadn't drank yet. And Leo's cup wasn't because he was a wild card. They didn't know he would come. Sorry for not updating for a while...

LEO POV

I shrieked and fell off my chair, startled, when the Slytherin demigods collapsed. Then I popped up and raced across the Great Hall to the three. Luna, Percy, and Neville were right behind me. I chanced a look around as I got to Malfoy's side. The Great Hall looked scared, frightened, confused, or a mixture of the three.

Dumbledore stood up. "Students, to your rooms!" He bellowed. "Everyone leave!"

I have to say, he was pretty scary for an old dude. As students and staff alike fled the room, the headmaster hurried over to the Slytherin table where all the present demigods were. He laid a hand on Jackson's forehead. The poisoned (I mean, even I had figured it out, I'm not dumb? Right?) half-bloods were becoming increasingly pale.

Neville started pacing, looking more and more worried and frantic by the second. Dumbledore stood and casted a spell which lifted Nico, Jackson and Malfoy into the air and set off in the in the direction of the Hospital Wing. We quickly followed him through the maze of corridors.

Seriously, though. A giant castle full of magic isn't a good place for a ADHD demigod. I was having trouble not wandering into every other corridor.

After stepping on Dumbledore's cloak for the fifth time, we got to the wizard's hospital wing. It was pretty cool, with all the colorful potions. I wanted to take a sip out of this yellow bubbly one when a lady came bustling out.

"Dumbledore, what is it?" she asked, then caught sight of the poisoned half-bloods. "Oh dear."

She told Dumbledore to lay them down on the beds then she disappeared into another room. She came out with an armful of potions. "Shoo, all of you!" she said.

No one was happy about it, and Percy got into a fifteen minute argument with her, but she eventually herded us out. "What now?" I asked nervously, fiddling with some gears.

Neville leaned against the wall. Percy stood uncertainly, watching Luna pace while she muttered, "This is not good!" repeatedly.

"We need to find the cure," the daughter of Athena said.

"Which is?"

"I don't know!"

Half an hour later, we trudged back to our common rooms. I fell into an arm chair, not bothering to go to a dormitory, and fell asleep. Naturally, I had to have a demigod dream, which I hate. It's like, all these monsters going 'I want to eat you!' or some other evil goddess laughing evilly.

I got the second one, apparently.

I was in a room that looked kind of like a smaller, darker Olympus palace. This weird snakey guy sat on a dark throne. I realized he didn't have a nose. That's just creepy.

I also realized, with my awesome perception skills, there were a bunch of cloaked guys holding sticks. Ugh! I mean wands. They seemed to be looking at the door nervously. Sure enough, the doors flew open and a lady stepped in. I mentally cursed. Percy was right when he told me about Nyx. Just great.

She started laughing, which echoed around the room. "The deed is done," she told the snakey guy, who I remembered a second later was Voldemort. Nyx smirked, looking triuphmant. She turned to right where I was.

"Another eavesdropper?" She asked lazily. "I'll tell you this, demigod. Surrender, or let the three die." A few of the Death Eaters looked around like they were trying to figure out who she was talking to.

Then she lunged at me, and I woke up in front of the smoldering fire. I stood up. This was bad. Bad, bad, bad. Like, as bad as...okay, I can't think of anything. I was sweating from my dream. Man, that goddess was scary. Pretty, but scary. Like Khione.

I was about to run up and tell Percy and Neville my dream when I looked at my watch. It was three in the afternoon, about time to go to Hogsmeade today. Whoops.

I ran out of the common room and raced to the Hogsmeade line, just coming in behind Percy. "Hello," I panted.

"Hi, Leo," he said tiredly, like he hadn't slept well.

"Look, I had a dream..." I told him the dream about Nyx.

"That's not good." he took a breath. "I had one a while ago too, but before they were poisoned. Dumbledore said he poison was irregular or something like that, so we can hope they might be able to get out by themselves. Look, were going to Hogsmeade to have fun. We'll worry about all of this war stuff later. Zeus knows we get a break."

"Sure, dude!" I said, grinning like a maniac.

A few minutes later, we were walking in a random direction when we passed the Hog's Head. Usually, I'd give it one glance and go straight for Zonko's, when Percy stopped me. "What in Hades are they al doing here?" he asked.

I peered through the windows and saw a bunch of students I recognized. The Weasly twins, Harry, Ron, Hermione, Dean, Lavender, even Neville was there.

"C'mon," Percy said, and we entered the pub, just as George Weasly pulled a sharp object out of his bag and waved it threateningly at someone who I'm fairly sure was called Zacharias Smith.

All the Hogwart's students stopped and looked up at us. I held up my hands in the universal gesture of peace. "So," I said. "Is there any chance we can, um, join you guys?"

"Sure," a Chinese Ravenclaw girl told us sweetly just as Harry opened his mouth. He closed it promptly.

"So, whatcha guys doing?" I asked, grinning again, sliding into a seat next to Fred Weasly.

"We're planning our own secret Defense Against the Dark Arts class, as Umbridge isn't teaching us anything," the same Ravenclaw girl said. A few people looked at us wearily, but no one commented.

(The DADA meeting may be taken or paraphrased from the fifth HP book)

"Yes, well," Hermione said. "Moving on...the point is, are we all agreed to take classes from Harry?"

I looked around at everyone murming 'yes.' Apparently this was a popular idea. A few people commented on their Quidditch practice, until Ernie spoke up.

"Well said! Personally, I think this is more important than anything we'll do this year, even our O.W.L.s. I'm at a loss to see why the Ministry has foisted such a useless teacher upon us at this critical period. Obviously they are in denial about the return of You-Know-Who, but to give us a teacher who is actively trying to prevent us from using defensive spells—"

"We think the reason Umbridge doesn't want us trained in Defense Against The Dark Arts is because she has some...some mad idea that Dumbledore could use the students in the school as a kind of private army." Hermione interupted.

Looking around, I saw that everybody looked stunned at the news except Luna and Percy. The son of Poseidon just sniggered and muttered something about 'Clarisse' and 'prissies.'

But Luna nodded thoughtfully. "Well that makes sense. After all, Fudge has his own private army."

"What?" I asked, at the same time as Harry. Usually, Luna was a lot more down to earth, and...well, sane.

"Yes, he's got an army of heliopaths," the blond said seriously.

"No, he hasn't," Hermione snapped.

"What are heliopaths?" asked Neville.

"They're spirits of fire," Luna said. "Great tall flaming creatures that gallop across the ground burning everything in front of—"

"They don't exist, Neville," Hermione said.

"Yes they do!"

"I'm sorry, but where's the proof of that?" Hermione countered.

"There are plenty of eyewitness accounts, just because you're so narrow-minded you need to have everything shoved under your nose before you—"

"Hem, hem," someone said in such a I jumped and nearly fell out of my chair until I realized the speaker was a red head girl. "Weren't we trying to decide how often we're going to meet and get Defense lessons?"

"Yes, sorry. We were," Hermione said, flustered.

"Well, once a week sounds cool," a boy with dreadlocks said.

"As long as—"

"Yes, we know about the Quidditch! The other things we need to decide is where we're going to meet..." she trailed off, looking around. Everyone looked stumped.

Then Percy snapped his fingers and sat up straight. "I know a place! Dumbledore told me about it. It's the Room of Requirement."

"Okay, where is it?" Harry asked

Percy frowned. "Um..." he said. "Oh yeah! Okay, seventh floor, opposite that tapestry of Barnapus the Barmy being clubbed by those trolls, you know the one?"

Everyone nodded. "It's Barnabas the Barmy, you know, and so is everyone agreed?" Hermione asked the group. There was a murmur of assent.

Hermione took a breath. "Right, w-well, I think we should all write down our names, just so we can know who was here. But I also think we all ought to agree not to shout about what we're doing. So if you sign, you're agreeing not to tell Umbridge—or anybody else—what we're up to. She rummaged through her bag for a second and pulled a parchment and quill and set it on the table nervously.

Percy, Fred and I cheerfully signed our names, but I could tell others looked less than happy about putting down theirs.

"Er..." said Zacharias slowly, not taking the parchment George was trying to pass him. "Well...I'm sure Ernie will tell me when the meeting is."

But Ernie didn't look like he wanted to write his name down. I sighed. "Look guys, do you really think Hermy—sorry, Hermione, will leave it laying around?"

"Yeah, she's smart, she'll put a curse on it or something," Percy added.

"Okay," Ernie said, and signed the sheet. No one else refused to sign after that, but I still saw people looking reluctant, including a girl next to the chinese-looking Ravenclaw girl. When everyone had written their names down, there was a sense of finality.

"Well, time's ticking, bye now," Fred said. He, George and Lee left the pub, and the rest of the group followed, leaving in twos and threes.

"Let's hope this'll work," Percy said.

(JACKSON POV)

(This is when their poisoned, where their minds are)

I woke up in a dark room. No, not dark, it was more like we were floating or standing in outer space, minus all the light, but I could still see Nico and Malfoy, looking bewildered, perfectly.

"Hello," a musical voice said from behind me. I spun around, my hand already reaching for my ring.*

Standing behind us was a girl, about seventeen. She had floating brown hair and wore a sparkly green shirt and jeans that looked marred by claw marks. I recognized her as a naiad, but she had shimmering golden eyes that had an odd glint in them. Whether it was regret, malice, or something entirely else I wasn't sure. She smiled sweetly.

"I am Roenaid," she said.

Malfoy frowned. "Have I heard that name before? I don't think I have, but it's familiar."

Roenaid's innocent smile twisted into a grimace. I grimaced too. I had heard her name before, but I never expected to meet her.

"Right, well, how do we get out?" I said.

She faced me. "Ah, the mistress' child," she purred, eyes glittering. It was unsettling.

"Just answer the question," I snapped. She flinched but tried to hide it.

The naiad turned to Nico and Malfoy. "You don't know who I am, do you? I'll give you a hint. I am the only naiad ever to turn rouge. I fought for the wrong side, and I paid for it dearly. The gods decided I wasn't bad enough for Tartarus, so they bound me to the poison."

Nico and Malfoy were staring at her, everything else forgotten. Roenaid smirked. "But the gods didn't count on me making this." She held up a golden jeweled cup and waved it. "This is the only way out."

"So we can't take it?" Nico asked anxiously.

"Of course. But there is a catch, mind you. Your freedom—" she waved the cup "—is also mine. What releases you from the place also releases me. But be warned, I will not rest until the gods are all destroyed." her beautiful face turned angry.

I exchanged glances with Nico and Malfoy. "We'll take it."

(PERCY POV)

Leo and I trudged back up to the castle. We were nearing the corridor to our common room when a loud crash and Greek swearing were heard from the direction of the Hospital wing. I glanced a Leo and we ran towards the wing.

Entering it, I found a very strange sight. The poisoned demigods were up and moving. Malfoy was leaning out the open window, yelling something. A trail of black dust was leading up to it. Jackson and Nico were pacing and cursing.

I cleared my throat. "Hi, guys. Um, what's going on?"

They looked at each other, and all started talking at the same time.

"See, we may of accidently released—"

"—gods bound her to the poison—"

"—wasn't our fault—"

"—creepy golden cup—"

"—I think it had blood in it..."

"Okay, guys, I talk like you guys are doing right now all the time, and even I can't hear what you prats are saying!" Leo yelled.

"You said prats," I noticed.

He frowned. "I've been spending way to much time with British dudes."

I sighed and turned to the three demigods, who looked slightly guilty. "Now, what happened?"

They explained everything. When they were finished, I sunk down into the bed. "So, you guys released a rouge naiad who will not stop at anything to destroy us?"

"Kind of."

"You guys are idiots," I groaned.

"Well, it was our only way out!"

"You told me that already. Sheesh, guys, you're at Hogwarts, for not even a month, and you manage to do this? You guys are even worse than me. And that's saying something."

Just then, Dumbledore and Madame Pompfrey came in. The nurse stopped in her tracks and stared. "They shouldn't—they shouldn't be able to..." she trailed off.

"Well, Madame Pomfrey, miracles do happen," Dumbledore said, smiling lightly. "Now, you five, off with you. I'll send someone to Luna and Neville to tell them you're all awake. Off with you, now!"

I hope you like it, sorry. I've been so busy with school, gym and Pottermore (awesome!). This isn't one of my best chapters, sorry again!

Sneak Peek: (Percy POV)

The next morning, we were at breakfast. I was hoping and praying to all the gods I knew (minus some annoying ones, like Zeus and Ares) that we'd have a peaceful day. Naturally, that couldn't happen.

The doors burst open. I automatically glanced to make sure all the demigods were in the Great Hall before turning my attention on the door. (Why does this seem to happen every other morning?) Jason Grace, son of Jupiter was there. He looked tired, like he'd been fighting all night, and he was limping.

"Nico, Percy...We need your help. Monsters are attacking."

"Why do you need our help?" I asked, standing up."

He looked at me. "Because, Percy, we can't kill them."

Nyx and Roenaid are back! Again, my cliffies stink. And I can't right chapters in which nothing big happens for the life of me. Ah well.
