When I had found out that all the Greek myths were true, I figured that the greeks were the only ones with their gods still out there. But, as usual, I was wrong.

The day had started out as any other. It was the summer after the attack on Manhattan, and with all the new campers and cabins, we still were adjusting to camp's new size. But more campers meant being on watch less often. Chiron had announced the new guard system at the beginning of the summer. Ever since the past summer's attack, monsters were constantly banging against the camp's protective shield, and some of the monsters were so ancient, they were able to get through. I had asked Annabeth what age had to do with ability to get through the barrier, but after a ten minute speech on "strength of age" and "power of previous knowledge", I was sorry I'd asked.

As a senior counselor, I was on duty more often, but I got to choose who I was on guard with. So there Annabeth and I were, on a hot July day, patrolling the top of Half Blood Hill, looking for any nasties who wanted to take a bite out of camp. And sure enough, halfway into our watch, ten Hyperborean giants appeared on the hill.

The attack caught even Annabeth by surprise. Not the attack itself, but the amount of giants. One or two of the old frosties had made their way to camp before, but ten at once? They must have been getting more organized. Annabeth whipped out the conch shell horn, and blew a pattern that alerted everyone of an attack. And without waiting for the backup, we rushed into battle. Oops.

In the beginning, I thought we were doing pretty well. Annabeth, and the ten campers who ran to join us, and I, were killing giant after giant. But somehow, we never seemed to kill them all. More and more Hyperboreans kept on appearing, almost out of thin air. The only warning that we had before one popped up was a Hyperborean sized blue light that appeared, and the giant stepped out of. We had never seen anything like it.

"We need more campers!" I yelled to Annabeth, as I dodged a giant's icy breath. "There's too many of them!" I slashed wildly with my sword, and there was blue blood everywhere, but there seemed no end to the attack. I kept on fighting, but there was too many of them to keep track of. Before I knew it, two of the Hyperboreans had cornered me and were pushing me back against Thalia's tree. I turned to find Peleus, but he was lashing out at another giant on the other side of the tree.

One of the giants laughed, but before it could use it's icy breath on me, a giant hammer flew out of nowhere and hit the giant in the chest. The other giant stumbled back dumbly, in shock.
A man with long blond hair and an even longer red cape suddenly jumped in front of me. "Die, Jotun!" he yelled in a deep, heavily accented voice. Who was this guy? And what in Hades's name was a Jotun? I was about to ask the man, then thought better of it, and ran to rejoin the battle.

As I fought, I noticed more non-demigods in the fight. A robot in an red suit was flying up overhead, sending out beams of light from his palms. A man in red, white, and blue holding a shield was shooting the Hyperboreans with a small gun, and I tried on to laugh. As if his puny gun could kill one of the huge giants. But he was pummeling the giants with his shield too, which seemed to be doing some good. I spotted a few other adults, but didn't have any time to really see what they were doing.

Suddenly, from behind me, appeared one of the most monstrous things I had ever seen, which is really saying something. I was maybe fifteen feet tall, green, and all muscle. Its face was strangely humanoid, though. I turned to Annabeth, who had at some point come to fight next to me.
"What in the gods name is that thing?" I yelled into her ear.
"I'm not sure." She yelled back. "I can't remember ever reading about any monster like this one."
That scared me even more then the actual monster. If Annabeth had never heard of it, then we were in real trouble.
"Lets concentrate on killing it now, and as Chiron what it is later."
Annabeth nodded. "Good plan, seaweed brain." And we charged.

But as I was about to swing my sword, I noticed that instead of attacking us, the monster was using its massive fists to pummel the Hyperboreans. It wasn't even paying any attention to the two of us. Annabeth had noticed that too, and I saw her hesitate. I shrugged.
"If it's on our side, we might as well leave it be. We can use all the help we can get!" She nodded and we went back to killing giants.

I honestly can't remember how long we were on top of that hill, hacking away at the ice giants. I was aware that more campers had joined the fight, but they didn't seem to help. As I fought, I saw more and more campers frozen in ice, their arms clenching swords, javelins, and other weapons.
"We have to fall back!" I shouted, but I didn't think anyone heard me through all the chaos. But it didn't really matter, because soon we would have nowhere to back up to except for into the camp's borders. It was a complete miracle that the giants hadn't made it into the camp already.

Just as I was about to give up hope, the entire hill lit up with a blue, green light. In a flash, all the giants disappeared. I nearly fell over in shock.
"Old magic." I heard Annabeth whisper next to me.
"Who cares what it was?" I exclaimed. "Who are these people?"
As soon as I asked the question, one of the adults appeared next to me. He had shoulder length black hair, and was faintly glowing the exact color of the light that had lit up the hill only moments before.
"I am Loki," he proclaimed, "and I am burdened by glorious purpose." He smiled, as if that was a perfect explanation to who he was, and how he had gotten here. I was going to ask for some information that was actually helpful in some way, but Annabeth had gone pale next to me.
"Oh, gods. We have to tell Chiron now. This is NOT good."
"What's not good?" I asked, confused. "Who are these people?" Annabeth just shook her head, and ran back to camp, presumably to get Chiron. Not having anything else to do, I turned back to the man who was apparently "burdened by glorious purpose", but he had disappeared. I made my way across the hill, surveying the damage and tallying up the block of iced count. How were we ever going to get all these campers down the hill so they could defrost safely?

I soon found Clarisse standing next to me. "Any idea who these people are?" I asked her. She shrugged. "No idea. But I'm sure Chiron will want to find out. And some of them are already trying to get into camp."
I nodded, noticing the guy with the cape that I had seen earlier trying to break down the invisible shield with his hammer, and the green monster banging on it with his fists. I took a deep breath, and yelled, "I, Percy Jackson, give you.."
But before I could finish, the iron robot landed next to me and announced in a metallic-y voice, "I, Tony Stark, give you permission to enter camp."

As thunder shook the hill and the man with the cape and the green giant tumbled down into camp, I stared at the robot in utter shock. But before I could say anything, Chiron galloped to meet us, with Annabeth at his side. The robot's gold plate on its headed immediately retracted, revealing a face underneath. The man ran to great Chiron. As they met, the man in the suit of armor bowed a little before shaking my teacher's hand.
"Chiron, it's been a while." He said, grinning.
"Indeed, Tony." Chiron smiled kindly, the way he looks at the new campers when they get their first bulls-eye. "You've been busy, I see. We have much to discuss. Follow me." And with that, Chiron cantered back into camp, leaving me, Annabeth, and 'Tony' to follow him.
