Hi readers!
Sorry I haven't updated in ages, but this chapter's a good one. It was co-written by ChildOfWisdom, aka Veronica. I wrote a chapter of her fanfiction, 'Warning: Zombie Takeover' and in return she helped by writing some of this chapter! It's very long, but full of battle, adventure, shock and other awesome stuff. Leave a review and tell me what you think!
Also, you need to give ChildOfWisdom's fics a read. They're incredible.

Lilly's POV:

I was still having to deal with Lief – the awkward-looking goat kid who I'd been to school with – trying to kill us. Now, there were two demigods who seemed to be working with him.
The first betrayer was tall, broad-shouldered and clad in a leather apron.
Eddie. He had a grim expression on his soot-lined face and held a large hammer in one hand. Veronica gasped in horror.
The second was a girl, slim, with brown hair and a silver diadem. Samantha nocked an arrow slowly.
"You!" Leon boldly stood in front of the rest of us, pointing his spear.
"Me." Eddie didn't look at all happy as he raised the hammer. Samantha smirked as she walked up the beach.
Lief chortled at our undoubtedly horrified faces. "Aw, did you think these people liked you? Oh, isn't that a shame…"
Leon growled. Something in him made him charge the grinning goat-boy. He lunged with his spear, but Lief deflected the blow, and with terrifying strength and agility, pushed Leon over and into the sand. I called out his name in shock.
Percy didn't have Riptide, but he raised his arms and the sea began to froth.
"GET 'EM!" Nico roared.

Annabeth drew her knife and stood sentry to Jack, Summer and Magenta. The two Apollo kids were trying to disinfect the spear wound, but blood was still trickling out.

I darted over to Leon and helped him to his feet. Lief effortlessly fought off Toby and kicked him to the ground with a cloven hoof. Our friend gasped as his breath was knocked out of him. I realized that we were underestimating the sneaky satyr, who was clearly a skilled spearman.
Veronica ran over to Eddie and fixed him with a steely glare. "You traitor!" she hissed, but did not move to strike him.
"Sorry Veronica," he replied, "but who can resist Tartarus' power?"
I watched her ready her blade until Lief and Leon duelling with lightning-fast strokes stole my attention. I saw my boyfriend beat down on the enemy, until a sneaky jab from Lief's spear knocked his sword from his hands. I snuck up behind him and went to push my blade to his throat, but he turned and punched me hard in the jaw. I fell to the ground and clutched my throbbing cheek. "Ow!" I moaned. Lief was good – too good.
After a brief tussle, Leon was doubled up in the sand beside me.
"Too easy!" the satyr grinned, and shoved Toby over towards us. He wasn't killing us yet, only herding us up whilst we were wounded… but why?

Veronica's POV:

I don't know why, but I felt a pang in my chest as soon as I saw Eddie. He was just as geeky as me, quoting Stephen Hawking in a meeting with Chiron. The sword I held in my hand, with its silvery hilt shaped like an owl's wings and the blade gleaming in the sunlight, had been forged by him out of kindness. Now he stood before me, hammer in his fist.
"How could you?" I demanded. I tried not to notice Lilly, Leon and Toby being tossed aside by Lief.
"I have been promised greatness and power." Eddie wasn't attacking me, I saw; only talking. Samantha was busy firing arrows at Tom, Percy and Annabeth, who were guarding Magenta and the others. Aston dove at Lief, thrusting his spear, but the satyr deflected and a spear-to-spear battle occurred with frightening speed. I was the only one facing down Eddie. The son of Hephaestus looked almost apologetic in his grimace.

"You're choosing greatness and power over your friends? Your camp?"
Eddie looked to the floor… then something in him snapped. His body tensed, and his grip on his weapon tightened. When he raised his head to me, his eyes seemed jet-black.
"I am choosing Tartarus," he hissed… then he charged.

The curious part of me wanted to know what had caused his change of behaviour, but the warrior part of me took over as soon as he charged. My hand quickly moved to my sword, deflecting his hammer from hitting me. I took a few steps backwards, carefully watching where I placed my steps.
"Eddie, think this through." I reasoned. "We're your friends. We're not enemies."
I didn't know, exactly, why I didn't fight him head on like I would do with any other opponent. Part of me still believed in that incredibly nice, nerdy kid I meant in camp. That part of me didn't want to fight a friend, even if I knew I was risking my life.
"I have already thought it through. I chose Tartarus." He said as he ran at me, hammer in the air.

His weapon came down at me but I intersected it with my blade, then tried slashing him through the chest but he dodged it. He swung again and I tried to block it again, but this time I was only half successful. The hammer clashed painfully with my hand and I quickly moved back, feeling some blood trickle from the cut. My eyes quickly met his, which still seemed jet black but something softened in them. The slightest bit. In return, I charged at him. I didn't get far before he moved, with speed greater than mine, and hit me with his hammer on my side.
The pain was horrible.
It felt as if I had been stuck by lightning and the pain moved throughout my body before I could even register it. I tripped on impact and fell to my knees. I tried getting up quickly after the fall but he got another blow on my shoulder and I felt something crack.

I cried out in pain but I didn't get time to do anything before his hammer hit me again, on my back. I feel to the floor, my face pressed against the dirt. I tried to blink the tears away, tears caused by pain, but I couldn't do anything. The voice in my heard urged me to get up and fight, but I couldn't. There was constant pain coming out from my shoulder and my side. Constant, throbbing pain. His hammer hit me again, this time aimed at my legs.

I knew I didn't have much time. My hand scrambled to find my sword that had fallen out of my hands and I quickly gripped on the hilt. Looking up, I saw his hammer come down at me one more time. But this time I was prepared. With all the will power I had left, I swung blindly and managed to knock the hammer from his hand.

It landed with a loud thump not too far away. I quickly moved my legs a bit to see if they could move and they could.

"Why do you even try? Can't you see we're already winning?" Eddie asked as he gestured around him. "Acknowledge your defeat. Accept it."

What I saw was horrifying.

Leon, Lilly and Toby had been all fighting against Lief. You would think that they were doing okay holding up three to one, right? Wrong.
Lief seemed to be possessed by Ares, because his moves were strong, they were fast and they were painfully precise. Leon and Toby were fighting head on with Lief, but he still managed to easily deflect each and every one of their blows. I could see Leon's frustration and I could also see what Lief was doing.
He was tiring them down. And it was working.
Annabeth fought with all her strength, both physical and mental, to defend Magenta but there were some nasty cuts on her arms that were slowing her down. Jack and Summer were busy trying to heal the fallen demigod, but even that was proving to be a challenge, taking into consideration the physical state they were both in. Nico, Percy and Mrs O'Leary were the only ones who seemed to be gaining ground on Samantha. Percy controlled the water while Nico and Mrs O'Leary attacked by shadows, but Nico had an arrow pierced through his left arm. It was bleeding gruesomely.

In other words, we were losing.

"Isn't it beautiful?" Eddie asked as he grinned.

I tried to get up from the sand but I couldn't. The pain had taken control of my body and my arms felt too weak to try to lift my body up. But I couldn't give up just yet. My friends needed help.

"You're sick,"

The last thing I heard was his laugh before everything turned black.

Lily's POV:

My world seemed to stop as soon as Lief's weapon came down on Leon and he fell to the ground. I let out a blood-curdling scream as Leon's eyes blinked shut and his face came into contact with the sand. I ran up toward where he was, only to receive a blow form Lief. I fell backwards due to the impact. He had caught me by surprise and the air was taken from my lungs. Toby saw this, got angry, and began to fight with new strength and valour. I stumbled to get up and managed to get over to Leon. I didn't like what I saw.

His face was caked with sand and blood and fresh cuts on his face bled. I picked up his head and placed it on my lap while I tried to wake him up.

"Leon, open your eyes…Leon, wake up!" I yelled desperately.

Behind me I could hear the slashing sound from Toby's sword as he fought with Lief. I wasn't looking at him but I could tell that he was fighting hard. I shook Leon's head in desperation but nothing was working. He wasn't waking up.

My heart felt like it was going to burst right out of my chest as I began to think of my life if Leon wasn't with me anymore. 'No, stop thinking like that, Lilly!' I scolded myself, 'he's alright. He's going to be okay. He'll wake up…He has to wake up.' I shook him by the shoulders and yelled his name.

Nothing.

It wasn't long before Toby fell to my side, slumped down with his eyes glazed over. He had a nasty cut running from his left shoulder to his right. His breathing was shaky and his eyes looked up at me, a second before they closed.

"Toby? No Toby, don't close your eyes! TOBY!" I screamed, as I shook him from his shoulders.

He didn't move. Tears began to burn from my eyes when I heard laughter behind me. My sadness was quickly turned to anger. I balled my fist and stood up, turning around and facing the guy I once thought was helpless. Now that I looked at him, he didn't look like that awkward looking goat kid that I met in school. He was the complete opposite. I didn't know him anymore.

'But now,' I thought, 'I don't care if I'd once known him or not. He's the traitor. He hurt Leon. He hurt my friends. He tried to kill Summer. He's going down.'

"Do you want to join your friends?" Lief asked as he laughed manically.

"How could you, Lief? How could you betray Camp Half-Blood? Your home? Your friends?"

"That place isn't home," Lief laughed. "This damned country's not my home! I come from the motherland; Hellas herself."

I gasped. Hellas is the ancient term for Greece; it's what the Ancient Greeks themselves called it. Lief was a genuine Greek satyr.

"My kind in Greece is as they are here. Lazy, filthy creatures, obsessed with trees and an old, dead goat god. They rejected me for my keenness to fight. Alone, angry and rejected; that was when Tartarus came to me. I was promised immortal life in Hellas for travelling to America. I was to ensure the prophesised six would die, and never slay Tartarus. That is why I found you out. I pulled a few strings and used a little bit of magic and a couple of death threats to bring all six of you to the same school. I got a job at camp, recruiting demigods. I bought you here, where I hoped to kill you. My hellhound failed, as did my attempts at killing Leon when he was injured – I jinxed you into stabbing him, by the way. I set Lamia on you, and told Samantha to bring her hunters to Central Park, where she would pretend to save your life, when in reality she summoned the Cyclopes. I thought I'd won when my shoes dragged Summer to Tartarus, but she was saved by Hades and Artemis. You've escaped me for so long… but no longer. Now, you die."

He stopped talking and charged at me at me with his spear, but I intersected with my knife. We fought on for some time until I managed to dodge his blow and cut his leg.

"You pathetic demigod!" He yelled as he furiously came at me.

I was intimidated by how fast he was coming and before I could move, he turned his spear and knocked me down to the ground. My head bounced up as it hit the ground, but I tried to blink away the pain and get up again. Lief kicked me, causing me to roll towards where Leon and Toby were. He was trying to keep us all together. I gritted my teeth and tried to get up again. His spear stabbed my foot. I cried out in pain.

"This is only the beginning of your suffering, little demigod. You should have known better than to have opposed Tartarus." He said as he brought his spear up to the air. "Prepare for pain."

His spear swung down and connected with my cheek so hard, the world started fading around me. All I wanted to do was help my friends and now, I was going to die with them.

Third Person POV:

It was sad to see that one by one, the heroes were being taken down.
Lief had defeated Lilly, Toby and Leon unmercifully. Veronica had fallen by the hand – and hammer - of Eddie, and now lay crumpled in the sand beside her friends. After Lief and Eddie had finished, they had gone to help Samantha fight Percy, Nico and Mrs O'Leary. They were putting up a good fight but our heroes were getting tired while the others seemed to be fuelled by their pain.

Eddie hammered down Mrs O'Leary and she barked and whined in pain. His hammer had hit the poor hell hound on its side, paws and head until she was bleeding. Nico and Percy ordered Mrs O'Leary to leave as they fought, but the loyal dog wasn't going to have it. She continued to bite and claw at him until she couldn't anymore. She fell to the floor with a giant THUMP.

"Mrs O'Leary!" yelled Nico.

He was fighting Samantha with an arrow sticking through his arm. The Roman huntress was definitely Roman in the way she fought. Nico had underestimated her ability with an arrow and he was starting to regret it. He knocked the bow out of her hands and crushed it under his feet before heading over towards his wounded dog, but she had ran up behind him and with her hands, stabbed arrows into his back.
The pain was sharp, spreading through him like electricity. He tried to turn around, swinging his sword in an arch as he tried to get her but her blood thirst was stronger than Nico's swings. He fell to his knees as he reached Mrs O'Leary and cried out as arrows were being stabbed into him.

"For Tartarus!" Samantha yelled.

Percy was now dealing with Eddie while Lief turned his attention to Annabeth, who was defending a hurt Magenta as Jack and Summer tried to heal her. Annabeth was one of the most experienced fighters but still, Lief was resulting to be a challenge. Annabeth and Lief engaged in combat, fighting with as much speed and ability as the other. But as they were fighting, Annabeth turned her head as Percy screamed out in pain and that little distraction was all Lief needed into disarm her. Her celestial bronze knife crashed onto the floor, feet away from her and she turned to glare at Lief. Her knife wasn't her only weapon.

"Do you really think you can win, Lief?" Annabeth began. "Tell me one time where the bad have beaten the good? The heroes always win, Lief. The bad can never prevail. The bad has never been victorious."

Lief chuckled at her words and walked over to her in a slow, maniacal pace.

"Daughter of Athena, your words won't do anything. Yes, the bad, as you say, has always had the misfortune of losing to you pathetic, weaklings. But we will make history. We will defeat you, your camp, Olympus and anything else that dares stand in our way!" Lief said as he swung towards Annabeth but she managed to dodge, barely. "Just look around you. Even your boyfriend is failing."

Annabeth didn't dare take her eyes off of Lief. She trusted Percy, she knew her beloved husband was a skilled fighter but last time she had taken a glance, things hadn't looked pretty. Samantha, who had managed to defeat Nico, had joined Eddie in fighting Percy. And whatever possessed them was giving them a great advantage over the young heroes. Lief just grinned at Annabeth as Percy was thrown beside the pile of injured or unconscious bodies. Bodies that belonged to her friends.

Annabeth felt as if someone was slowly pushing in rusty nails into her heart. Only four remained. There was Jack, occupied with healing the barely-conscious Magenta, as well as an exhausted Summer, Tom and herself; who had no weapon.

"Many have tried and many have failed," Lief said. "Your friend, Luke, tried and failed. And so did many before him. But remember this day, daughter of Athena. Because today will be the day where we win and you don't."

Lief lunged forward, as Eddie and Samantha came up from behind the grey eyed woman and they quickly over-powered her. Pain, coming from every direction, was the last thing Annabeth was allowed to feel before her body shut down, in an attempt to stop the pain.

"No!" Summer said as Annabeth was dragged from the floor and thrown into the pile.

Everything suddenly started to seem hopeless. Emotions of all sorts flooded Summer, some she recognized and some that she didn't.

"Remember this day!" Lief told the other traitors.

Lief's foot crushed down on Magenta's head with a violent kick. Summer didn't have time to react as she was pushed aside by Samantha and carried away to her beaten friends. Jack had barely finished applying a salve to Magenta's shoulder, but was tackled by Eddie. Summer hoped her half-brother would prevail, but his only weapon – a xiphos – was pulled away from him as the son of Hephaestus kicked him, punched him, and then threw him onto the pile of defeated demigods.
As Magenta was dragged away, the only one on his feet was Tom. He pushed his sword up to Lief's throat. "I swear to Tartarus and back, Lief Evergreen, that I will kill you," he snarled.

"Cute," smirked the satyr, who kicked Tom very hard in the groin with a cloven hoof, punched him in the gut and judo-flipped him over his head and into the sand. "That was relatively simple."

Samantha and Eddie clutched their weapons, guarding the pile of broken, beaten and bruised demigods. Lief slowly walked over to the hole in the ground – the one that Summer had exited Tartarus through, and the one that the monsters had attacked from.

"Tartarus," he murmured, "lord of the pit, king of the abyss, true god of the underworld. Bearer of limitless and unbounded power, he who is both punishment and justice. I, your servant, Lief Evergreen, beg you to rise from the depths and claim these children of the gods as your first sacrifices!"

"That didn't sound good," muttered Toby.
Something in the coal black pit began to stir. Lief grinned.
That was when an exhausted Summer, who was trying desperately to ignore the bruise on her arm, was kicked sharply by Nico. The son of Hades leant in and whispered: "Hang on a second… where's Bella?"

There you go!
Hope you enjoyed it! Please shower ChildOfWisdom in your adoration; I'm sure you'll agree her writing is incredible!
Love you all :D
