The next morning, Nightwing stood by the jet ramp, supervising the team getting on board. Batman was already in the pilots chair. Most of the team was already on. Nightwing watched the last few straglers, when Dr. Fate appeared out of nowhere.

"Dr. Fate?" Nightwing said nervously. He felt like a kid that had just been caught with their hand in the cookie jar. He really didn't want to have a showdown with him. "Uh, what brings you here?"

"Do you think I don't already know what is going on?" His deep unearthly voice echoed.

"Uh." Nightwing stamered.

"I respect the boundaries of the panthanons, but I also know that the outcome of this battle not only affects the world, but the universe. So, we have come to an agreement."

"We have?" Nightwing said nervously. By now, the majority of the heros had come out to see what was going on.

Dr. Fate then removed the helmet. "I will be fighting instead." Zatara said.

"Dad!" Zatanna ran into her father's arms and they hugged tightly.

"It's always good to have you." Batman commented.

"There's a bit more to it than that. I am fighting for my family. I am a son of Hecate, goddess of magic."

"Dad?" Zatanna looked at him as though meeting him for the first time.

"I have kept you safe from my world for so long, but I suppose I should have known that I couldn't keep you from it forever. You have the blood of Olympus in your veins and are a Legacy of Hecate. This is your world too that you are entering."

Zatanna looked like she was having a hard time processing this earthshaking information. "These demigods are, I mean, I'm related to . . ."

"Family relations are rather blurred when it comes to the Olympians. The only ones that you would really consider family would be other children of Hecate."

"So they would be your brother's and sisters?"

"Yes. Perhaps we will meet some. It has been some time since I have been at camp."

"Ahh, then you haven't heard." La'gaan said with a huge smile on his face. "Perseus Jackson was given any reward he wanted after saving the world, even godhood, and he turned it down to make the gods swear to include all the gods and goddesses in the council and for every god and goddess to have a cabin for their kids at camp. He even made them swear to claim their kids by the age of thirteen. He's so awesome." La'gaan ranted.

Everyone was silent for a moment. "No I hadn't heard. Maybe we could visit camp together?" He smiled at his daughter.

Zatanna smiled back.

"All right,looks like Zatara is coming with us. Load up, let's go." Nightwing called out. Everyone loaded up and they were off.

Nightwing couldn't help but feel himself get anxious the closer they got. It had only been a couple of days since he last saw Reyna, but he couldn't wait to see her again. With the speed of the plane, it seemed they were there in no time. Batman skirted around the target and about a mile out they found a large base camp with several tents set up. Batman lowered the plane gently a few yards from the camp. Nightwing suddenly felt nervous. He was going to see her again, but this time everyone was going to be judging her. The plane's ramp lowered and they exited the plane with Nightwing and Batman in the lead. He saw two figures in the distance with bright purple capes walking toward them. Nightwing couldn't help but be drawn to her. Everyone else followed behind.

Soon Nightwing, with the Justice League behind him, was standing opposite of Reyna, Praetor Frank Zhang, and several other kids behind them. She looked stunning dressed in her full Roman armor.

"Ava, Justice League." Reyna called out and put her fist to her heart.

" Uh?" Nightwing wasn't sure what to say.

"It's how we respectfully greet allies." Reyna smirked.

"Oh." Nightwing said stupidly.

"Thank you for coming, and on time, which is more than I can say for the graecus."

"The Greeks." Kaldur translated.

"You were able to get the Atlantians." Reyna said as though she were impressed.

"Some. Aquaman was unable to come, but Kaldur and La'gaan are always good to have in a fight." Nightwing pointed them out. "This is Batman, my mentor. Green Arrow, Arsonal, Red Arrow, Bat Woman, Shazam, Flash, Kid Flash, Zatara, who we just found out is a son of Hecate, his daughter Zatanna, Beast Boy, Bumblebee, Empress, Black Lightning, Static, and Artemis."

"Artemis? Not sure how the Hunters will react to that. I'm Praetor Reyna Rameriz. This is Praetor Frank Zhang. These are lieutenants over the legions of Rome. The Hunters of Artemis," she glanced at Artemis, "are over there." she pointed to the right of the camp. "You will be meeting Thalia, her first lieutenant and a daughter of Zeus. The Amazons are over there." She pointed to e left of camp. " I believe you have already mety sister Hylla, queen of the Amazons." She gave Nightwing a knowing look. Nightwing unconsciously rubbed his jaw. "Hopefully the graecus will be here soon. In the mean time we have a tent set up to discuss battle strategies. If you will follow me."

Reyna turned and led them back the way they had come. Nightwing hurried to catch up to her.

"Looks like you still had a good turn out."

"Do you think we have enough mortals? Reyna worried under her breath.

Nightwing glanced back at the crew he had brought. " They may not look like much, but they pack a punch. We'll protect you."

"I just hope to stop them in time."

"We will." Nightwing assured her. He desperately wanted to hold her hand, but thought better of it with so many watching.

They were just approaching a huge tent when a black dog the size of a semi literally jumped out of the shadows. Nightwing immediately got into a fighting position along with the rest of the Justice League. Green Arrow, Red Arrow, and Arson drew their bows, and Shazam flew into the air. He thought Reyna would draw her sword, but she only smiled.

"Nico, good to see you make it." Reyna said pleasantly to the dog. Then he realized she wasn't talking to the dog. She was talking to a kid sitting on top the dog. He had black hair and was wearing an old leather jacket that looked like a replica of the WWII pilot jackets. Behind him was another kid with bright blond hair.

"Like you ever doubted." Nico smirked. The giant dog walked in a circle a couple of times and them promptly laid down, opened it's gapping jaws in a yawn, showing everyone it's razer sharp teeth, and then fell asleep. "Hope you're not planning on attacking my Hellhound." Nico glared at Nightwing and the Justice League members.

Reyna turned to them. "I know it's a bit of a shock, but she's friendly."

"I thought you were supposed to get mortal's that didn't want to kill us." Nico said casually as he slid off the Hellhound.

"Oh, stop." The blond scolded. "How else did you think they would react to a Hellhound. She's a sweetheart, really." He assured them.

"To our friends." Nico added cryptically.

"This is Nico Di'Angelo, Son of Hades and ambassador between Camp Jupiter and Camp Half-Blood. And, this is Will Solace, son of Apollo and head medicus." Reyna introduced them. "These are the hand picked mortals of the Justice League. I hope the rest of the graecus are close behind." Reyna questioned.

"Percy had to round up some pegasus, but they should be here soon. Will wanted to set up early." Nico explained.

"Now that is melting out of the shadows." Flash whispered to Batman. Batman shot Flash an intense glare that caused him to raise his hands in surrender.

"Oh, Percy wanted me to warn you that he got Clarisse to come." Will said. "She's a daughter of Ares. She killed the drakon during the first war. She can be . . . difficult, but she's great in battle. If she gets here beforehand he does, expect attitude."

"Great." Reyna said less than enthusiastically.

"The graecus are here!" A shout called out.

"Percy must have pushed them." Will said impressed.

Everyone turned to see what looked like a flock of birds headed toward them. It wasn't long, however though, that the flock got bigger, and you could see that people were riding on top of them. Nightwing watched in amazement as the pegasi circled them once and then landed in a stampede not far from the tent. It was an impressive sight.

"The greeks sure do you know how to make an entrance." Shazam looked on excitedly. Nightwing knew that the rest of the Justice League members were equally impressed along with himself as they watched the beautiful pegasi. Several young kids had doubled up on their back and were now climbing off. Unlike the Roman demigod's in their pristine armor, these demigods wore jeans and orange t-shirts with just a leather armor over their chest and back. They each had a sword strapped around their waist, but it all looked a bit mishappen.

At the head was a tall guy with black hair. He helped a young woman with curly blond hair off the Pegasus first before he got off. The girl walked purposely over towards them, while the young man pulled out a box of donuts and fed it to the black pegasus' he rode.

"Ava, Annabeth Chase." Reyna called out.

"Ava nothing." Annabeth said as she enveloped Reyna in a hug. "You gave us the scare of our lives. Don't you ever do that again."

Reyna looked surprised at the hug, but reciprocated it. "I'm fine." She sputtered.

"She scold you yet?" The young man said as he strode over.

"You're late." Reyna deflected.

"Give me some credit. I had to negotiate."

"Is that what the donuts are for? I've told you, those aren't good for Blackjack." Will scolded.

"It's a life or death situation!"

"Uh, this is Perseus Jackson, son of Poseidon and Annabeth Chase. They're basically the leaders of the Greek camp."

"Ready to pass that mantle, anytime. And, call me Percy. Only gods and monsters call me Perseus, and I don't much like either one."

"That explains why you piss them both off. How are you still alive?" Nico asked.

"Good question, Death Boy."

"It's obvious, for times like these." Annabeth answered soberly.

"Guys, these are the mortals of the Justice League." Reyna soildered on.

Annabeth eyed them critically. "You must be Nightwing." She singled him out.

"Uh, yeah." Nightwing said uncomfortably.

Annabeth exchanged a look with Reyna that clearly said that she knew about them. "It's a pleasure to meet you." She smiled knowingly at him.

"Shall we go?" Reyna prompted. He cheeks looked a little red.

"Unfortunately, we're missing one more." Annabeth sighed.

As if on cue, a shout went out, "Graecus!"

Nightwing turned to look in the sky and saw a golden plane headed toward them. He blinked and then saw that as it got closer it's wings were flapping.

"Is that . . ? I don't believe it, it's a dragon!" Shazam said excitedly.

Sure enough a brilliant golden dragon landed almost on top of them. "The party has arrived!" A kid sitting atop the dragon yelled. But there was something odd about this dragon. It not only looked like metal, it was made out of metal. A latino kid slid down the tail of the dragon. "Leo 'McShizzle' Valdez, at your service."

"Ignore him." Another voice said. They looked up to see a young girl floating down as if by magic to where they were.

"Calypso! Wasn't sure you were going to make it." Percy smiled. Annabeth, however, looked unimpressed.

"Let's get this meeting started." Annabeth turned on her heels and entered the tent.

Reyna turned to Leo. "Don't let that thing wander." She glowered at him before turning and entering the tent.

"You blow up Rome one time and you're a walking time bomb." Leo muttered under his breath, then he shouted, "I was possessed!" He then turned and petted the dragon. Then suddenly the dragon began to fold into itself until it had shrunk down into a golden briefcase. He turned to see the Justice League members staring at him with their jaws dropped. "Transformers, eat your heart out." Leo smirked.

"That's physically impossible." Flash insisted.

"Dude, we're all physically impossible." Leo snarked as he followed Calypso into the tent.

"Here we go." He heard Batman breath under his breath as they entered the tent. The tent was much larger than it looked. It was lavishly decorated with rugs across the floor and cushioned chairs around a large table ladened with food.

"Wow." Nightwing said impressed.

Reyna smiled at his reaction. "The Romans don't go skimpy on anything."

"Yeah, if it were the Greeks, we'd be meeting around a campfire." Percy sat next to Annabeth and placed his arn comfortably behind her. Nightwing took note that they were most definitely a couple.

"I don't see anything wrong with that." A girl with spiky black hair said. She looked like a heavy metal rocker with her black ripped jeans and heavy duty black boots. But the whole image was ruined by the silver parka she wore and a delicate circlet on her head.

"Hey, at least we'd have smores." Leo snarked. There was a light breeze and a stack of gooey s'mores, perfectly cooked, appeared before him. "Sweet!" He dug in.

"Uh, you are spoiled." Thalia said disgustedly.

"Well not everyone can be as badass as you." Percy snarked.

"Everyone, this is Thalia, daughter of Zeus and Artamis' lieutenant over the hunters."

Nightwing and the rest of the league, however, we're too fixated on food as suddenly appearing.

"Go ahead," Reyna encouraged them, "ask for anything to eat."

Kid Flash wasted no time and shouted, "A bucket of chicken wings, five hamburgers, four trays of fries, and a liter of root beer." There was another breeze and and everything he had asked for appeared in front of him. "Sweet!" And with that, Kid Flash went into speedster mode and inhaled his food in less than a minute.

"Dang!" Percy commented. "I don't want anyone teasing me about inhaling food. I don't hold a candle compared to him."

"Excuse him. He's a speedster. We have a high metabolism." Flash glared at him.

"What?" Kid Flash said cluelessly.

"Maybe we should get this meeting started." Batman suggested.

Nightwing turned his attention to Reyna, but he was surprised to see that she was looking at Percy and Annabeth. "Right." Annabeth sat forward and placed a paper on the table. " So the building is three stories high. And they have erected a tower on the top . . ."

"Perhaps this will help." Batman interrupted as he placed a hologram display on the table and turned it on. A three dimensional display of the building came up.

"Ooh, is that the hologram three thousand with full interaction capabilities? That is sweet!" Leo gushed.

The rest of the Demigods looked at it with some trepidation. "There's no internet on it." Nightwing assured. While the demigod's relaxed, the Justice League gave him questioning looks. "Monsters can track them through the internet." He explained.

"As if so many of us gathering in one place wasn't a big enough flashing sign." Percy quipped.

"He's so cool." La'gaan whispered.

"It's fine." Annabeth said getting down to business.

"The tower on top is to launch the virus in the air. But the actual virus that they are working on is below it on the third level." Batman interrupted. "The lower levels are filled with most likely a mix of monsters and humans. If we do a combined direct attack on all sides, we should be able to make quick work of it."

"Or they'll make quick work of us without ever leaving the building." Leo said amid smacks of sticky marshmallow. "The building is surrounded by traps. Cleverly hidden, too."

"And you know this, how?" Batman asked.

"I sensed them as I was flying by. They obviously know we're coming."

"Could you disarm any of them from a distance?" Annabeth asked.

"Not these. They're of the more volatile kind." Leo continued

"I'm sorry, who are you?" Green Arrow asked.

"Leo 'McShizzle' . . ."

Calypso smacked him across the back of the head. "Leo Valdez would be better."

"You're no fun. Fine. Leo Valdez, son of Hephaestus, at your service."

"Hephaestus?" Beast Boy looked at him questioningly.

"Someone didn't do his homework." Leo teased "Hephaestus is the god of fire and blacksmithing." Leo explained. "All I have to do is touch something technical I know how it works. I can tell you guys are covered in tech." He waved toward Nightwing, Batman, Batwoman, Green Arrow, and Red Arrow.

"So how do you disarm them?" Annabeth asked.

"Well, from what I gathered, they're all connected. A genius interconnected design that runs to one place: that building." Leo pointed at the hologram. "They can orchastrate all the traps and explosions, like a symphony. It's beautiful." He sighed.

"Maybe, if you're the one controlling it." Arsonal commented.

"What if you were?" Nico smirked.

Leo suddenly didn't look so confident "Shadow travel? Me? I thought I would be fighting on the ground, sort of speaking, with Festus." He definitely looked spooked.

"You should try it. It's a rush." Percy smirked.

"What's shadow travel?" Nightwing asked.

"Shadow travel," Nico smirked, "is when I travel through the underworld to go anywhere in the world, instantaneous. Imagine hundreds of thousands of souls are crying out, trying to latch onto you to come back to the land of the living or drag you down to the fields if Asphodel." Nico explained it so darkly that Nightwing could have sworn that the room got darker.

"Have you ever taken a mortal?" Nightwing asked.

"Not an option." Reyna glared at Nightwing.

"I know this system, and I can hack into just about anything. You are going to need someone technical in there."

"Well, Nico, what do you think would happen if you took a mortal?" Annabeth looked like she was seriously considering it.

"I don't know. I don't usually hang around mortals." Nico admitted.

"Guess."

"Best case scenario, he gets the chills. Worst case scenario, he goes mad." Nico said calmly.

"I can do it." Nightwing insisted.

"And what happens, when you arrive mad? The mission will be compromised." Batman pointed out.

"Then we do a trial run. Nothing too far " Nightwing suggested.

"Sounds good to me." Nico smirked and grabbed hold of him.

Nightwing was enveloped in complete darkness. Voices howled all around him. He felt like he was flying incredibly fast, and then he was back in the daylight. He felt slightly nauseous and out of sorts, but for the most part he was in one peace, but he wasn't sure about his mind. There was a catasymphony of shouting and yelling. Nightwing thought for a moment that he was still in the underworld, except for the brightness. Then he thought he had gone mad. Then he realized that they were arguing about him. It looked like World War III was about to break out.

"I'm fine!" He shouted over the din. The noise died down as he picked himself up off the floor. "I'm fine." He said again. He realized he was across the room, so he walked back over across from Reyna, next to Batman.

"That was inredibly risky. Don't do it again.". Batman growled. He had on his full intimidation stare, except it didn't seem to be working with these kids.

Nico narrowed his eyes back. "It was just across the room."

"I think what Batman is trying to say is that it would be best to seek permission before just acting." Reyna placated.

It was clear that this alliance was starting off rocky. "So now we know that I can shadow travel, so Nico can sneak me into the control room."

"So who's going with you?" Percy leveled his gaze at him.

"Why would anyone need to go with me?" Nightwing questioned. "I work best alone.

"Until you encounter monsters." Annabeth pointed out.

"We usually go on quests in groups of three.". Percy fiddled with a pen in his hand.

"I think Reyna should go." Annabeth decided. "You two started this, it only makes sense you finish it."

Reyna met Nightwing's gaze.

"Makes sense." Percy agreed.

"Are we all in agreeance?" Reyna asked.

No one raised their hands or said "aye " but no one objected either.

"Then all we have to do is decide who fights with who." Batman started.

"Agreed " Annabeth interrupted. "But there is one blaring problem that needs to be addressed."

"What now?" Batman was looking a little irate at this blond girl.

"Our . . . uniforms are so different that no matter how stupid the monster or mortal is, they'll know who to attack." Annabeth pointed out

She was right. How could he have missed that. Even Batman looked a little taken back. "What God are you the daughter of?" Batman asked.

"Goddess " she said with a slight irritation in her voice. "I'm the daughter of Athena, goddess of wisdom and battle strategy."

That explained a lot. He had been wondering why Reyna was so willing to hand over the reigns to her. It seemed that all the demigod's relied on her council. She must be experienced.

Batman raised an eyebrow, which Nightwing took to mean that he was somewhat impressed. "What do you suggest?"

"Well," Annabeth scooted to the front of her seat. "I was thinking of swapping." She eyed the group before her trying to judge their reaction. "Think of it. A monster sees you in that getup and knows you're mortal. It's like walking with a target on your back. If a Half-Blood is in that getup, . . ."

"They'd be in for the shock of their lives." Percy laughed. "That's brilliant." He beamed at her.

"You want us to just hand over our gear and wear that armor?" Batman looked less than doubtful, he looked appalled.

"He's got a point." Frank interjected. Annabeth fixed her gaze on him. "Don't get me wrong. It's a great idea. But if I were to wear something like that, I wouldn't be able to fight in it. How do you even see through the masks?"

Nightwing saw that he had a point. He wasn't sure he would be able to fight in armor either.

"I might have an idea." Zatanna said shyly. All eyes turned to her. "An illusion spell. It has its limitations, like it only lasts an hour, and whoever you dress up as, would have to look similar to you. For example, Nightwing and Percy Jackson have similar builds and the same hair color so they could easily be illusioned to look like the other."

"And you would be able to still fight?" Percy asked as he eyed Nightwing's skin tight outfit.

"As far as you would be concerned, you would still be in your armor, and he would be in his gear. Nothing would change, except your apparance." Zatanna explained.

"Who did you say you were?" Annabeth asked.

"She's my daughter, a legacy of Hecate." Zatara said with a note of pride.

"What do you think, Lou Ellen?". Annabeth asked a young girl, maybe a few years younger than Zatanna sitting behind her.

The girl smiled widely, and said, "I think I have the awesomest niece ever. It's manipulating the mist at its best. We could totally do that."

Nightwing thought it odd to have a girl younger than Zatanna claiming to be her aunt. But he guessed that's what happened when your grandmother is a goddess.

"Good. You two hook up with the Hecate cabin and figure out whose switching." Annabeth ordered, then she smirked at Batman, "As for the rest of us, now we can talk about strategy."
