UPDATED 2014 BECAUSE THE ORIGINAL SUCKED.

3rd Person POV

The entire Cullen family was gathered in the lounge when they heard the splash. Emmett, Carlisle and Jasper were watching basketball, Edward and Bella were playing chess, Alice and Rosalie were reading various catalogues, Esme was making dinner for Renesmee, and the youngest of the Cullen family was cheering on her mom as she watched her parents' game.

A shimmery image of a centaur appeared in the middle of the room.

What the hell? Emmett thought. Who's the horse dude?

"Emmett, behave," Edward hissed.

"Chiron!" Carlisle exclaimed, recognising the creature.

"Carlisle, Esme," Chiron acknowledged. "I trust that you are well."

"Yes, we are." Carlisle smiled. "Did you call for any particular reason?"

Hurry up. Emmett thought impatiently. I was watching basketball.

Edward elbowed Emmett in the ribs.

"Yes, there is – hang on, do I see extra members of the Cullen clan?" Chiron asked, confused.

"Yes you do," Carlisle grinned, walking up to each person in turn. "This is Bella, Edward's wife, and Renesmee – or Nessie, as we prefer to call her."

"Um," Bella interrupted. "I don't prefer it. I call her Ren."

Carlisle chuckled, but continued. "She is Edward and Bella's daughter."

"Hello," Renesmee greeted as she climbed up on to Bella's lap. "You're a centaur aren't you? Mommy read a story about them to me one night, didn't you mommy?"

"Yep." Bella smiled at the centaur in question.

"Hello Bella, Renesmee," Chiron nodded at each as he said their names. "How does that work then? I thought you couldn't have kids?"

"It's a long story." Edward explained. "I'm sure it'll come up at some point."

"Right then...what I was going to ask was-"

The Cullens could hear a pounding heart about to enter the room. It was pounding so hard, they thought it might burst out of the ribcage.

"Chiron! Annabeth needs – oh sorry, I didn't know you were Iris-messaging."

"It's all right, Percy. This is Carlisle and his family: Esme, Edward, Bella, Renesmee, Rosalie, Emmett, Alice and Jasper. They are vampires; I am going to ask them to help us in our situation here at Camp Half-Blood."

What situation? Carlisle thought, confused.

"Oh, right. Hi, everyone. I'm Percy, son of Poseidon." Percy grinned at the Cullens.

"Really?! Son of Poseidon?! Daddy has told me all about Greek Gods! Poseidon is the Sea God right Percy? Can you do cool stuff with water?" Renesmee asked excitedly.

Sea mist suddenly swirled round Percy and made him fly off the ground. When he reached the ground again he pointed his finger at a glass in the Cullen's sitting room and it filled up with water. "Does that answer your question…what was your name again?"

"Ren," Renesmee answered, making Bella nod in approval that she didn't say 'Nessie'. "That was awesome! How did you do that?"

"Well –," Percy started to explain.

"You two can talk about that if the Cullen's can come here," Chiron interrupted their conversation. "So can you?" Chiron turned to face the Cullens, his face pleading.

"Chiron, I don't think you've explained yet." Esme pointed out.

"Ah, yes. Sorry." Chiron apologised. "Last year, we managed to defeat Kronos, but he had one very loyal follower who has...for lack of a better word 'a way with people'. He has the special ability to manipulate people's decisions, and he's managed to convince several hundred demigods to join his side. We've heard that they're planning to attack Camp Half-Blood in the next few weeks, and we could really use some extra help."

"Before we accept, I shall have to ask my family. Can you Iris message us again in five minutes?" Carlisle asked.

"Yes, that's fine." Chiron said impatiently.

Carlisle waved his hand over the mist and Chiron's image disappeared.

"So, what do we think?" Carlisle turned to face his family.

"I think it would be awesome!" Emmett said, grinning.

"I'm not sure, what have they ever done for us?" Rosalie pointed out.

"Rose, we're not repaying them or anything. Chiron is my friend, and he needs us." Carlisle explained, softly.

"Fine." Rosalie grumbled.

"I'm not sure either, Carlisle." Edward piped up.

"Why not?"

"I don't want Bella and Renesmee fighting in a war. What if something happens to them?"

"Nothing will happen to me, Edward." Bella rolled her eyes. "At the moment, I'm stronger than you. Don't forget that."

"Fine, but what about Ren? I'm not having her fighting." Edward crossed his arms.

"I'm sure not all gods will be fighting, she can stay with one that is staying on Olympus." Bella reasoned.

"Okay." Edward gave in.

"Esme? Jazz? Alice? What do you think?" Carlisle asked.

"We should help them, they are in need." Esme replied.

"Yeah, I agree." Jasper said.

"I think we should definitely help them." Alice stated, confidently. "And at the moment, I can see that we're gonna win." She grinned.

"Great-" Carlisle got cut off.

"Hello." Chiron appeared back in the room. "Have you come to a decision yet?"

"Yes. We have decided we will help you. When do you need us?"

"As soon as you can!" Chiron exclaimed. "We will all be forever grateful. Our top three campers, Percy, Annabeth and Thalia, have been assisting the satyrs to find new demigods to help us in the war, but none of us will be good as you guys fighting-wise."

"What about Jake?" Bella asked. "The werewolves could help Camp Half-Blood as well."

"Werewolves? I thought you guys weren't exactly… peachy at the moment." Chiron looked confused.

"Because of certain situations to do with Renesmee, Bella and Edward, we have made a stronger treaty and I am sure they would be happy to help. Bella, can you –," before Carlisle could finish, Bella bid a quick farewell and ran off towards La Push at lightning speed.

Two minutes later, Bella appeared back at the Cullen house with six wolves padding behind her, Jake, Sam, Embry, Quil, Paul and Seth. Five out of the six had unreadable expressions, but Seth looked rather excited.

"Hey guys," Jake greeted once he had phased back to human and put on his clothes. "We tried to get Leah to come but she still hasn't completely warmed up to the whole blood-sucker idea."

"Jake," Renesmee scolded, sighing and raising one eyebrow.

"Sorry." Jake said, shamefully staring at the floor. "Leah hasn't completely warmed up to the whole leech idea. Happy?"

"No." She said simply.

"Leah hasn't completely warmed up to the whole vampire idea then, okay?"

"Yes." Renesmee nodded. "Has mummy explained what's going on?"

"Yeah, and we would be more than happy to help centaur-dude and his little friends."

Suddenly a wave of water landed on Jake. What's more, it didn't hit anything else!

"Centaur-dude and his little friends?" Percy snarled, crossing his arms.

"That was pretty cool!" Renesmee said, laughing.

"Glad you like it, Ren!" Percy replied.

"Percy!" A female voice called. "Where in Zeus' name are you?!"

"Oh, sorry I have to go, I think that's Annabeth calling," Percy apologised.

"Who's Annabeth, Percy?" Renesmee asked.

"My girlfriend." Percy answered her, blushing.

"Ooh! That's cool! Can I meet her?"

"I'm sure she'll want to when you get here, as will I." Percy smiled. "Anyway, I have to go. See you later, guys. Chiron, when you're done here could you meet me in my cabin?"

"What's your cabin like-" Renesmee started to ask, but her mother interrupted her.

"Ren, you can ask Percy when we get there in a few hours."

"So, you're coming later then?" Chiron asked.

"I think so! We'll see you in a few hours." Carlisle said.

"Bye Chiron!" Renesmee called.

"See you guys!" Chiron called. He quickly got out his sword and disconnected them.

A wave washed over Chiron and he was gone.

"You guys ready to go?" Carlisle turned back to the rest of the Cullens.

"You want to go now?" Jacob asked.

"Yes, we should go," Esme replied. "We need to get some training in before they invade."

"Okay then," Seth said, excited. "Let's go."
