N/A:

Sorry for the delay. Answering the reviews:

1) UltraMickey:Let see here: Awesome plot and interesting chapter but you have horrible grammar when it comes to this story. I mean no offense, but for example "Then he said, And then, I though about it and said:" These examples does not entertain the reader, though ur plot may be interesting. If u keep using then, and, and other words, it gets dull and boring. Like I said, I mean no offense, but please change ur writing style. Other than that, keep it up, but I expect some changes.

R: Thank you. But do not worry because now I am taking help of a Beta. (Anaklusmos14.)

2) Aesir: Thanks for all the answers as well as great strategy. Also thanks to Anaklusmos14 for his awesome job. Great chapter.

Percy's POV

Artemis called more than two hundred hunters to unite in Central Park and prepare for war. I was sure less than thirty hunters had survived in the last war against the Titans, so I was surprised that Artemis got so many girls to would be difficult to travel with more than one hundred people, so Artemis was accompanied by only twenty hunters, including Thalia, who is her constant companion as her hunters decided to settle away from the Romans. If the Romans would not get involved with Greeks, then the hunters also preferred not to mix with the with so many hunters together it could end up attracting attention from mortals, the mist helped us hide them. All Artemis and I had to do was wait for evening and the enemies to knew enemies could get in from the outside Central Park, so she strategically placed hunters in areas to prevent any kind of surprise attack.

"Lady Artemis, do we have any way of knowing if Hades is having a problem? Like if he was unable to escape or contact anyone for help." I asked.

"Perseus, do you know what an empathy link is?" Artemis asked patiently.

"Yes, but isn't that just between demigods and satyrs?" I asked.

That seemed like a strange idea because I didn't think I had any kind of link to Hades.

"Not exactly." She replied.

"In the case of gods, we can see the other gods, demigods or mortals even when one of us is not sleeping. It is because of this that we can find other gods and mortals with ease." She explained.

I remembered that a few years ago, when Apollo tried to locate Artemis, but couldn't.

"But that does not always work, right?" I asked.

"No. If the Fates decide, then they can block our abilities to see other gods or even demigods and mortals." She answered.

I had the impression it was not necessary at the moment because as time worked differently in the Underworld compared to the world of mortals, we wouldn't be able to guess the time enemies could come out of the Underworld entrance in Central the hunters had split up in groups to keep watch around the park in the event of external surprise attack. It was already getting dark when I began to feel that something strange was moving inside the park and it seemed like was coming from the lake; most likely some kind sea monster.

"Lady Artemis, I think I'm sensing something coming out of the lake." I told her.

Artemis also seemed to sense that presence and we took off toward the lake. The monsters traveled through the waters in a different way than mortals, so it was no surprise that there were monsters coming out of that lake. Some of the hunters were already waiting and ready for the had permission to kill any monster, so she could help. It took me a while to realize that as I was god of loyalty, I could help any ally so I could help in the battle. Finally we reached the lake and I realized that Thalia was close to us.

"Lady Artemis, the situation is serious." She said as she fired an arrow at a Telekhine who had reached the shore of the lake.

There were more monsters than I thought; I saw several Telekhines trying to get out of the lake, but the hunters arrows were able to prevent them from approaching. But what really drew my attention was the Hydra that had necks long enough that it could reach those who were near the bank of the lake while the monster still remained in the center of the monster managed to catch several hunters at the same time and I had the feeling that Artemis was getting so angry that she would take her divine form and advance against the monster, but it could end up incinerating any hunter or unsuspecting mortal.

So much has happened in just a few seconds.

Artemis's POV

I realized that one of the Hydra's heads was looking for Thalia and I was considering attacking it, but I knew the monster feared approaching Perseus and I, thankfully Thalia was Perseus and I were surrounded by a strange chain that came from behind and began to strangle us.

Thalia was distracted for a moment and one of the Hydra's heads was faster and grabbed immediately the head of the Hydra shook vigorously as if being electrocuted and then exploded, scattering green repugnant mucus to all sides. I saw Thalia falling quickly to the lakeshore.I knew that sooner or later, such a thing could happen. But that does not mean I did not care about my hunters. I wanted to break the chains, destroy the monster and save Thalia, but I was completely immobilized. I heard Perseus screaming Thalia's name, but he could not break the chains either.

Then we turned in the direction the chains had come from and saw two demigods we looked at them, I heard one of the say:

"We were able to capture two gods in the same day. Our masters will be pleased."One said.

Perseus and I tried to move toward the two demigods but it was too difficult. When they realized what we were trying to do, they tightened the chain so tight that we were nearly near choked unconscious. The way the demigods manipulated the chains, it was clear at least one had to be a child of Hecate.

"Do not even think about it. These chains are made with the three most powerful magical materials in existance. This will torture you before it sends you to Tartarus." One of the demigods means that they managed to get Stygian Iron of Underworld. To do that they would have had to have many allies and worked for a long time to create these weapons. The only strange thing is that I have never heard such a weapon, yet it seemed familiar.

"I hope these work, they are similar to those Egyptian ribbons, but made of Greeks materials. Maybe we should call Seven Ribbons of Ven ..." One of the demigods said before the other demigod interrupted.

"Shut up. Our teacher was inspired by them, but that does not mean that we should start explaining it to these gods."

I realized that the Hydra was approaching us, trying to take advantage of us while we were detained and Thalia was lying unconscious. Meanwhile the two demigods continued to strangle us, but I refused to give up as did Perseus.I remembered what those chains resembled. I hadn't seen them in over 2000 years. They were used as a weapon to "ban" gods from another place ... I really did not like to think about that time. I had to think fast and protect my hunters and Perseus.

I was trying to think of how to escape the chains, but I couldn't get my arms or my two knives free to try and cut myself free. I would teach these two mortals not to treat me like prey. I realized that the demigod seemed to stop trying to push me harder, although I continued to be stuck. Then I realized that the two demigods were looking at me strangely and even Perseus looked at me a little surprised. I took their moment of distraction and quickly pulled the chains, making the demigod who had me tied down fall to the ground. Perseus did the same with the other demigod. I finally got my knives free and managed to cut the chains to free myself. I was about to attack the two demigods before they could cause me anymore trouble.

Suddenly, the earth underneath the two demigods opened and the several skeletons grabbed and pulled them into the earth before it closed and left the demigods unconscious and buried. When I turned to face the Hydra, it was almost submerged as if being pulled by something else even bigger than the I looked, I saw there was a guy coming and I figured he was responsible for calling the dead. He was pale and wore dark clothes. After a few seconds I recognized who it was.

"Nico?" Perseus asked.

Before he could say anything, I left to try and save Thalia. I saw that my hunters who were around the lake had gathered around her. When I approached, they moved away and I could see that Thalia was unconscious and was full of injuries. Perseus and the son of Hades caught up to me quickly.

"There is still time to save her." Nico said.

Being a child of Hades, I knew he could tell and was correct. I immediately touched Thalia and healed her. I continued until I saw all the bruises disappear. After a few seconds, Thalia opened his eyes and murmured, "Lady Artemis? I ...I'm sorry I got distracted. "

"Don't worry Thalia, you are healed now. I have full faith in your abilities." I told her with a smile.

Thalia seemed to realize that Nico was there and was a little surprised.

"Nico? Why are you here?" She asked, fearing the answer.

"Well, I thought it would be good idea to help. But I also came to tell you guys something. I came to warn you that the key to Hades was stolen." Nico explained solemnly.

He did not need to say anything else. I knew it would mean that the monsters and souls of the dead would find it easier to escape the underworld and Tartarus, those allied those demigods could be causing a bigger threat than we expected.I saw that Perseus also understood. He must have heard of the key as well. It now made sense that those demigods were confident when they used that weapon made with Stygian Iron. If they had the key of Hades, then it would be virtually impossible for us to escape Tartarus.

"But how is it that that the mortals have managed to steal from Hades? Hades cannot do anything to help stop them?" Perseus asked.

"They did not dare to attack my father directly for fear of giving him a reason to fight against them. My father was restricted to sending monsters after them but they managed to defeat the monsters and get inside my father's palace. It was already too late when he sensed someone invading his palace and they managed to get the key." Nico explained.I thought for a moment, until I remembered who could be capable of doing that, but I had no proof. Perseus looked at me and guessed who I suspected.

"Maybe it was Janus? He was on the side of the Titans and I think his powers would be useful for entering the palace of Hades and then to escape easily." Perseus said.

"You are most likely right." I told him.

I did not want to look like I wanted someone to blame, but it is true that I was suspicious of the minor gods. I do not think they allied with the Titans and led a war against us just because some demigods received no attention. On the other hand, I could cause quite a bit of turmoil if I persisted blaming someone without any evidence.

"What about those three demigods?" Perseus asked.

"They must already have reached the other side. Although they received some help, I'm sure some monsters of the underworld will want to attack them in some way." Nico said.

"Should I be able to see them?" He asked me.

"Yes, just focus on them." I told him

Percy's POV

When Artemis said that I should be able to see them, I focused on the three demigods. When I did, I could see the three demigods flying in the chariot of Demeter. It was similar to when Hestia showed the past to me a few years ago, only in this case, I was looking at what was currently seemed to be in danger, battling dozens of Keres. Watching them fight alone, without my direct interference, made me wonder what they were thinking. I was shocked when I realized that I could see their feelings.

Clarisse violently attacked the monsters using her spear. She seemed even angrier if that was possible. For a moment I could see her fighting in the fight against the Romans, shouting the name of Chris before charging forward violently against several Roman. I was sure she wanted to prove her value again to her father, Ares.

As for Will, I could understand that he still held a grudge against the Romans. Many children of Apollo have died in recent years and many died in battle against the Romans that was caused by the descendent of Apollo, Octavian. He wanted to prove to his own reputation and that of his brothers. I realized that Will was even more useful in this mission because Katie had an injury apparently caused by one of the monsters in her shoulder, but fortunately Will had healing power.

Katie wanted people to value the children of Demeter considering that since ancient times they have not been highly valued. If possible, she would show that she was as strong as the other demigods.

I pulled back from the vision and my attention returned to where I currently was.

"Percy, the enemies are already trying to get out the Door of Orpheus and are probably receiving help from the monsters." Nico said.

"Wait, how do you know that the demigods are invisible?" I asked Nico.

"They are wearing helmets of invisibility. The monsters looked like they were attacking nothing, but one of them probably lost their helmet and became visible." He replied.

"We must be careful, they can attack us by surprise as we are distracted by monsters. Thalia, I want you to alert the other hunters and the Romans about it. And also warn them about the fact that they are using the weapons of the underworld." Artemis said.

"Yes, Lady Artemis." Thalia said respectfully.

Thalia left with Nico and the other hunters leaving Artemis and I alone.

I remembered when we were captured, Artemis had a different appearance. Her hair seemed darker, her eyes looked like that of a cat and his hair was longer than normal and smooth and the jacket seemed to have colored deerskin.

"Lady Artemis, about when we were captured ... What those demigods were saying about Egyptian things? And for a moment you looked different." I asked cautiously.

Artemis hesitated before responding, "That was only because I remembered when the others gods and I were in Egypt and some my old personalities came out."

"So that means you too were Egyptian gods besides being Greeks and Romans?" I asked.

"There are different cases. When we went to Egypt, we were confused with other gods and thus were influenced with an alter ego in that place. In the case of the Romans, they were the descendants of Greeks and as "Roman Gods" we were technically ourselves." Artemis said.

For a moment I wanted to say that I had heard her think about the fact that she united with Selene, but I preferred not to touch on that subject. Actually I was coming to the conclusion that Selene had faded and gave some of her power to Artemis.

"Now I remember, mortals say that the gods went to Egypt because they were fleeing from Typhon." I said.

Artemis smiled for a moment before she replied, "And leave Olympus unprotected? Actually, we moved Olympus and fled to Egypt just to lure him away from the original Mount Olympus, because Typhon was irrational enough to be confused. He was foolish enough to not realize he could directly attack Mount Olympus to destroy us. "

"I see." I replied.

I saw Artemis look at the moon.

"You usually get stronger when you have a full moon?" I asked her.

"Yes." She answered.

"And Perseus, I hope you do not think I'm weak just because they caught me." She said to me.

"Of course I don't think that." I told her immediately.

Artemis smiled and then approached me, but hesitated. "Thank you, Perseus. Now it is time for us to fight the enemy armies."

I nodded to her and we went to where the battlefield was going to be.
