Author's note: Sorry! I accidently combined theis chapter with ch. 10...oops! This is the actual ch. 11. ~~:D

Percy and Nico slowly and cautiously turned around. Behind them was a figure about Nico's height, standing in front of a random tree. The figure was draped and hooded in a black cloak with a face paler than snow. Black liner coated her eyelids and scarlet lipstick coated her lips. The color of her eyes matched her lips perfectly; they were redder than blood. But where her nose should have been was a small stretch of cartilage barley raised with two tiny nostrils. She lifted her claw-like hands and removed the hood from her face to reveal hair black as night slicked back into a ponytail. Despite her creepy appearance, for some reason, Nico wasn't afraid.

"Percy, get a load of this! Edward Cullen and Lord Voldemort had a kid!"

Before Percy could react, she spoke. Her voice was raspy and tense, but oddly soothing.

"Don't try me, demigod." Whatever it was moved to the left, putting the tree she was blocking into view. There, tied to the tree and gagged was Luna Logan.

"Let her go!" Nico groped for his sword. It was so cliché, but Nico didn't care. He would never let anything happen to Luna.

"Not so fast, demigod." She smiled a cruel smile, and took out a whip. It oddly resembled the whips that Percy had seen in the hands of the furies.

"Who are you?" Percy asked, advancing and pointing Riptide at her throat.

"Ahhh, Anklusmos." She smiled that wicked smile again. She flicked the sword from her neck and began to pace in a circle around the two free demigods.

"My name is Aizella. I am the daughter of the Megaera, the Fury of jealousy, and Hades, God of the Underworld."

Nico's heart stopped. "So am I-" Nico was interrupted by a noise behind him.

"Ahhh, Hecraetia, you could make it! And Yes, Nico," Aizella put a finger under his chin. "We're your half sisters."

Nico glared at her so hard, it could have melted ice.

"I like Bianca better."

With one swift move he slapped her hand away and drew his Stygian iron sword. Hecraetia moved over next to her twin sister. The only difference between them was their eye color. Hecraetia's were gold, Aizella's were red. Then, they each removed their cloaks and hissed. Tattered, rotten wings sprouted out of their slimy backs. Their skin morphed into a brown scaly exterior. Their teeth grew sharper and pointier, snarling wildly. Their feet changed into claws with sharp talons. They had changed into furies.

"Oh my gods!" Percy's eyes widened. "They just changed into furies!"

"They can't be as powerful as the actual furies, though! They're just the offspring!" Nico called back.

Aizella and Hecraetia began to flap above them. All of the sudden, Aizella pulled out a long pointed stick.

"The Pelian Spear!"

Aizella aimed the spear at Nico and Charged at him. He barely had time to react, but he managed to deflect its blow. Aizella cried out in disgust and charged again. This time he was ready. She flew down at him and he ducked, but managed to catch his sword on her foot. Green slime spilled out and she screamed. While she was occupied with her wound, Nico raced over to the tree where Luna was tied up. He slashed at the ropes, and managed to cut about half of them.

Aizella noticed what he was doing and charged at him again. She grabbed his shirt with her talons, and lifted him up into the air, high above central park. She stabbed at him with the spear, but her short arms couldn't reach him. Nico reached for his sword, but realized it wasn't there. Nico let out a stream of curses, and grabbed at the Pelian Spear. It was all in vain; her talons wouldn't let him go. The sharp claws dug into his sides and he could feel the blood oozing down his body. She leveled off her flight, and he was so far up he could barely see the park. The atmospheric pressure pushed at his ears, causing tremendous pain. The he realized a terrible fact: they were in Zeus' domain. Children of Hades took a huge risk crossing the boundary lines of the gods. But then he realized something. Aizella was a child of Hades too. She was in just as much danger! Nico had little time to let this thought sink in when she jabbed at him with the spear. He ducked and dodged, each time attempting to grab the spear. Finally, he caught it, and yanked so hard that Aizella was dragged off course. Her head ducked and they began to fly straight down. Nico tried to cut her with the spear, but his current angle wouldn't allow him the leverage. He didn't know what to do. Aizella ducked her head toward him, and hissed so horribly that she was able to grab the spear out of his hand. "Right back where we started" he thought. But that wasn't the case.

Nico yelped as he heard a magnificent crack from above, and a flash of electricity. Zeus! Zeus' aim never failed, and the lightning struck Aizella and zapped through her body.

Nico felt the jolt as the electricity surged through Aizella's body. Because her claws still gripped his sides he equally shared the effect. He was still conscious when Aizella made one last stab at his shoulder with the Pelian spear. It gouged his shoulder to the bone, ripping away layers of flesh. He was unaware that his shoulder was his Achilles spot, but now he knew exactly where it was. He was too stunned to react as blood streamed down his left arm. At least it wasn't his right.

Without warning, Aizella lost consciousness as an effect of the lightning. They began to plummet down back to the ground. Nico figured that her claws would go lax now, but they wouldn't budge. Nico desperately tried to free himself from her clutches, but it only made his shoulder throb worse. He cried out in anguish, knowing the situation was hopeless. His stomach did a flip inside of him as they began to descend faster and faster. The demigod began to pray to the gods. All the ones he could think of, including the minor gods, and even his father Hades. Still no help.

By now, he could make out the outline of central park, and silently thanked the gods. At least he could get back to Luna and Percy. Percy! Nico wondered how of if he was able to hold up against Hecraetia. Nico gagged. The thought of the two horrible demons being his sisters made him sick. His vision began to fade; he was losing too much blood. He could almost make out Cedar Hill when everything went black.

Meanwhile, Percy wasn't making any great progress with Hecraetia. Luckily she didn't possess the spear, but she did have a whip. She was fast, subtle and an experienced fighter. But so was Percy. Plus, he was partly invincible; thanks to his recent bath in the River of Styx. The Gods only knew how old she was. Percy constantly found himself wondering why no one had any record of these beasts. Where had they been all this time?

At that moment Hecraetia cracked her hideous whip, striking Percy square in the face. He swung Riptide, catching the tip of the whip with his sword. She counteracted, torking her wrist so that her whip gripped Percy's sword. She pulled, and Riptide was freed from his hands. He gasped aloud, surprised at being disarmed. Riptide landed about 30 yards away from him. He didn't have enough time to retrieve it. Hecraetia flapped her heinous wings that spanned 12 feet. Percy was forced to back down onto plan b. he anxiously looked around for any sign of water. A pond, puddle, fountain? Nothing. He silently cursed, realizing the only choice he had was to retrieve his weapon.

Hecraetia flew at him, her face inches from his. She hissed ferociously. Percy ducked and rolled, but he only cleared 10 yards. The half-fury realized what he was doing, and put herself between Percy and his sword. She slowly advanced, making him retreat. At once she charged. Percy ducked under her ugly body and ran to his sword. I "Only 5 more yards! C'mon, come on!" he told himself. He was almost there when Hecraetia knocked him flat on his back. He hit the ground with such force that he felt the ground rumble. He looked to his left, and clambered over to grab his sword.

Hecraetia shrieked in frustration. Percy leapt to his feet, only to be knocked down by the magnificent force of Aizella and Nico falling to the ground. Hecraetia, too, was caught off guard. Percy quickly examined Nico and Aizella's situation. From his angle, he could barely see Nico, but he could tell that he was trapped in her claws. He was a tiny bit relieved when he saw no sign of consciousness from Aizella, but worried when he saw the same from Nico. He prayed that his cousin would be okay.

He didn't have enough time to finish this thought when Hecraetia began to narrow in on him. She backed him up farther and farther until he reached the tree where Luna was held hostage. Percy was tempted to cut her free, but he didn't want to put her in danger. She squirmed, trying desperately to loosen herself from the ropes that bound her. At once, Hecraetia cracked her whip. Percy ducked. By some miracle the whip slashed the ropes in half and Luna was freed. She un-gagged herself and let out a huge sigh of relief. The half-fury was too busy with Percy to notice her, so Luna scampered over to Nico.

She cupped his pale face in her hands, and called his name. No answer. Luna noticed that Aizella's claws still held him captive and began to pry them off. She managed to budge them a little bit at a time, but not enough to free Nico. Frustrated, she circled around the hideous beast in search of a sharp object. She also attempted to figure out why Aizella was dead. Nico couldn't have stabbed her; there was no blood. She didn't have a broken neck or anything. It had to be something more powerful. She remembered them flying up higher than her eyes could see into….Zeus' domain! They must have been hit by lightning! Luna was right. She, like Nico before her realized that this meant that Nico might be dead too.

Luna ran back around Aizella to Nico and tried to free him one last time. She poured all of her anger and frustration into breaking Aizella's grasp. The claws rubbed her hands raw, but finally she freed him. She dragged him away from the claws and laid him down. It was then that Luna noticed the horrible wound to his shoulder. She was disgusted, but mortified. Luna began to cry, wondering if Nico was still alive. It felt like all she ever did was cry. She listened for a heartbeat, and found one. She began to cry even harder knowing that he wasn't dead.

Then, Hestia's necklace captured her gaze. She had never seen it before. Curious, she took it off of him and put it around her own neck. Oblivious to its magic, she pressed the skull trying to feel the material. All at once she felt a calm soothing sensation, as if she were getting a massage at a spa. Colors floated into her mind softly, as she started to understand what she never had before. The 'Eureka!' moments calm to her in the form of the prophecy. "In the beauty of the trees there is a being hidden well" That was Aizella and Hecraetia hiding in Central Park. "That will once be discovered by the ancestor of hell" well, Nico was the son of Hades, and he had pretty much found them. (Besides her being held hostage by them of course) "One shall fall by the weapon of heroic kin" it was obvious to her now that Nico had been wounded by the Pelian Spear. "One shall be healed by the blood of the fairest skin" was still an enigma.

"Wait! No it's not!" she said aloud and scrambled around for Nico's sword. It had previously fallen here before. Within a few minutes she had her hands on the Stygian Iron blade. She knelt over Nico's shoulder. She knew who the last line of the prophecy was referring to. She knew what she had to do.

The first cut stung. She swiped the blade over her wrist, letting the blood leak out and fall into Nico's shoulder. She did a second cut and a third. She didn't even notice the tears streaming down her face. Slowly, scarlet droplets seeped into Nico's wound, silently working there magic. Luna couldn't stand to look at it anymore. She turned away from the gruesome sight, turning her wrist upside down.

And when she looked back, Nico was healed.

Nico gingerly opened his eyes and smiled. Luna was so overjoyed that she forgot about Percy and Hecraetia, and leaned down to kiss him. She had never felt anything better.

"What are we doing here?" Nico said

Luna didn't answer; she was still kissing him.

"Seriously," he said between kisses

Luna's eyes widened. "The batt- Perc-Hecraetia!

"OH!" Nico leapt to his feet, coming to his senses. He grabbed his sword from the ground next to Luna and didn't bother to wonder why it was stained with blood. After all, he had no clue what Luna had done.

Nico got within a 20 yard radius of Hecraetia and Percy. He knew it was no use fighting them; they were too powerful. Instead, he decided to use his powers. Nico grounded his feet and held out a hand. What felt like black smoke erupted inside of him, and all of a sudden, Hecraetia fell to the ground, dead. Just like her sister.

Percy turned his gaze and saw Nico. He smiled so big it could have lit up New York City. He never expected that seeing a kid in black jeans and leather jacket would make him so relieved and happy. Percy ran to his cousin and wrapped him in a huge embrace. On the other side of Cedar Hill, Luna couldn't help smiling too. She quickly adjusted her clothes and dashed over to join the group hug, with all the pain and joy of knowing they were safe.
