Alright so there seem to have been some confusion. To clear it up, Rissa is flashing back on the war, telling you certain things, like how long it lasts (five years), who fought in it, yadda yadda yadda. Anyway, this is the Dawn of the First Battle. Rissa is still seventeen. I will fix this and make it clearer when I'm done writing the whole thing.

Chapter Sixty One

There were so many weapons. You could get hit from anything. We used guns, and all kinds of blades. We used magic. Any weapon you could think of, we would use it.

Everyone from their world was organized. We kept all of the wizards together, all of the demigods together…it was all organized because certain people fought better with certain people beside them.

There would be certain leaders of certain groups. Despite their fighting, Castiel led the angels into battle. Percy Jackson and Jason Grace led the demigods. Katniss led District 13, with some recruits from other Districts. I felt really bad about that. Katniss's mentality sort of shut down after everything that happened in Panem.

The first day seemed to last forever. We stood on the battlefield, weapons ready. And we watched as the other army ran towards us.

...

They came over the hill, and charged us.

"Are you sure about this, Rissa?" the Doctor asked, beside me.

"Yes," I whispered. Tears quietly ran down my cheeks.

And we put up our blades to theirs.

...

Before the battle, we had charmed every single weapon with magic. Now our blades, our bullets; they could kill anything. They would certainly kill demons.

And I slaughtered them. We charged into battle, and I swung my sword upon them. I swung it at their necks, and chopped off their heads. I stabbed them in the heart, cut off limbs.

And I went at it for hours. I used my body size to my advantage. I usually had a partner. Sherlock stuck with me most of the time, because John stayed in the hospital wing. He would fight one, while I would sneak up on the opponent and take them out.

We would switch off. Sherlock and I fought for hours, until joining John in the hospital wing. Molly and John were running it. They also had Draco Malfoy, now a Healer, and Castiel. Cas would lead the angels telepathically. If someone was seriously hurt on the battlefield, they would pray to Cas and he would go and heal them. But he mainly stayed in the hospital wing to help heal the wounded.

...

When fighting, you tried to stay away from the wizards. You might get hit by a Killing Curse.

The angels were amazing. They would take out demon after demon, and they never tired.

At the end of the day, the demons had retreated.

...

The group of us: Winchesters, Avengers, Harry, Sherlock and John, and the Doctor and I, stayed up late at night in our strategies tent.

We had lost thousands of soldiers. No, thousands of people.

Everyone else was standing in a circle, talking. I sat in a chair, with my head in my hands. They were discussing how to….get more soldiers, or something. I didn't really care.

Today was one of the worst days of my life. And I knew that it was just going to get worse.

Among the fallen: Alec Lightwood from the Mortal Instruments. Piper McLean from the Heroes of Olympus. Stiles Stilinski from Teen Wolf. Haymitch Abernathy from the Hunger Games. Belle from Once Upon a Time. Monroe from Grimm. And those are just to name a few.

The talking quieted down. I looked up. Everyone was looking at me.

"What the hell are you all looking at me, for?" I asked. "You're the geniuses."

"Rissa," the Doctor said quietly. "You know things. Know things that even I didn't know. Maybe you could figure something out."

I rubbed my eyes. "Um…alright. Alright. After all, I may not be a genius, but I am smart. I took a test when I was younger," I rambled, giving me time to come up with an idea. "It was the end of the world, and only twelve people were still alive. But there was only enough food in their shelter for seven of them to survive, so you had to kick five people out. You had to choose who would stay and who would go. I chose the correct, most logical answers, so obviously I have something going on in my brain. I choose what seems logical to me."

"So, any ideas?" Sherlock asked.

"Cas?" I asked.

Everyone turned to face him.

"Yes?" he asked.

"I need you to go down to everyone who died. I need you to ask all of them, every single one of them, if they want to come back to life or stay dead. But you need to give them a choice."

"Why wouldn't they want to come back to life?" Cas asked.

"Because their lives have been hard, and they deserve peace if they want it," I said.

"Okay," Cas said, disappearing.

"Alright," John said. "That gives us more people. And we took out at least one eighteenth of the other army. But I think we need more soldiers than the ones we already had when we started."

Another idea was starting to form in my mind. Out of all of our fallen soldiers, none of them were angels.

"Sam? Dean?" I asked. "I need you to help me write up a list of angels who would help us if we brought them back to life. Cas can add more later."

The boys and I sat down and started a list while the others planned more strategies and techniques. Tony and Bruce were busy coming up with different weapons that could kill large parts of their army at once.

"Alright," I said, writing several names down. "I'm pretty sure that these guys will help us."

"Gabriel," Sam read. "Balthazar. Alright, I can see those guys helping us. But do you really think that Naomi and Anna will help us?"

"Yes," I said. "In the end, Naomi realized her mistakes. She will help lead the war and will help you guys with Metatron when we're done. Anna will be a bit more difficult, but she will still help us, because she despises Lucifer. Naomi might even convince other angels to help, the ones who won't join because of Cas. I'm thinking that Gabriel will lead, while Naomi and Cas will have their own divisions. The ones with Cas will be chosen carefully, so they don't try to kill him or something."

"Alright," Dean said. "Makes sense. Um, Zachariah and Uriel are out. They won't help us. Alfie might,"

"Oh, you mean Samandriel?" I asked. "You're right, I almost forgot about him. And Cas had some friends who died in the fall. Like the real Ezekiel. He might help."

We continued writing the list until Cas came back. He looked over the list, and added pages and pages of names.

"Um, everyone said yes," he said when he was done.

"Everyone? You mean everyone who died?" I asked.

"Yes." He said. "They all agreed to come back to life."

"Thank you," I said. I turned and looked at the Doctor. "Doctor!"

"Yes?" He came over. Normally he'd clap his hands, or something, but he was much too somber for that. I really hoped that this wasn't getting to him.

"I need you to make an announcement to the army. Tell them that when the die, the will automatically come back to life. If they want to remain dead, have them move to a certain spot in the room and take down all of their names."

"Alright," the Doctor said. "Be right back."

He ran out of our tent and called the army together.

...

We all followed the Doctor out to the platform to watch him make his announcement. (We have a platform that makes it easier to make announcements.)

"Alright everyone. When you die, you will automatically be brought back to life if you want to. If you want to be left alone when you die, please move over to the side." The Doctor gestured over to an empty area near the stage.

Nobody moved. We waited a couple of more seconds, but nobody moved.

"Do…do you all want to keep fighting for us?" I asked quietly.

It was quiet, but everyone could hear me.

"Yes!" Someone shouted.

"Yeah!" Someone else added in.

And then everyone was cheering.

...

The cheering grew louder as they watched their fallen comrades walk back to them. Everyone embraced each other as the army became whole again.

And that was one of the reasons I mourn. Because people keep dying in horrible ways, only to come back again and again to be slaughtered.

War tarnished the soul.

And we were only on Day 1.

But we were strong.

We were whole.

And we could not die.
