I came up with this after reading The Serpent's Shadow, when I considered what would happen if Carter and Sadie ever did investigate the "unexplainable magic" in Long Island.

Once you finish, be sure to vote on my poll and name a fear I could use on two of my other stories!

I do not own The Kane Chronicles, The Heroes of Olympus, or Percy Jackson. Happy?

Sadie POV: We Accidentally anger a fully armed army.

You'd think that after I saved the world, (three times, no less!) nothing could surprise me anymore. Well, it looks like I was wrong.

It all started on an average August day. The air was balmy, carrying just a hint of autumn, though it was still plenty hot enough to remind everyone that it was still summer.

I was on a mission with my annoying older brother, Carter, [What, you know it's true!] and my sort-of boyfriend(s), Walt/Anubis.

Carter was in the lead, acting every bit the leader we all know he is. Walt walked beside me, hand in mine. It was rather awkward, moving through the dense trees while holding onto someone else. Not that I was complaining.

Anyway, we were attempting to find the source of the unexplainable magic we'd been receiving reports of for months. The most alarming of these was in Long Island, just because it was so close. If the magic was a threat to Brooklyn House, then it was up to my insufferable brother and me to solve it.

"We should be near about there," Carter called out from the front.

"Well, what are we waiting for? Let's go kick some magician bum," I laughed as I strode purposefully forward.

For those five meters or so, I'm sure I looked good, with my freshly dyed hair [turquoise streaks this time] flying behind me and my form-fitting black linen clothes. And then I hit the invisible barrier, breaking the illusion.

I flew backward a good meter and landed flat on my back. I sat up slowly, pulling the bits of grass and leaves from my hair, glaring at the two boys all the while.

Honestly, I'd have expected Carter to laugh at me. It's what brothers do. But Walt-Walt-was roaring with laughter too.

"If you're quite finished," I reprimanded primly, nose in the air, "We have work to do."

The pair nodded, helping each other to their feet. Neither of them helped me up. Honestly, boys!

"I think there's some sort of barrier there," Carter mussed, staring at the place where I'd fallen.

"No, really?" I questioned sarcastically.

"Let me," Walt intoned, moving cautiously towards the invisible wall. He moved his hand close to the place where I'd impacted, touching it with his fingertips. A faint sound, like crackling electricity shot out as Walt's had flew backwards. "Hm…" he considered.

"Sa-hei!" he shot out. The barrier gleamed, visible for the merest second before fading away.

Walt frowned. "That's some strong magic," Carter commented. "What if we tried all three, at once?" he suggested.

I reached out and gripped Walt's hand as Carter grabbed a hold of mine. Together we faced the barrier."

"On the count of three," Carter called. "One…two…three…"

"Sa-hei!" we called out.

The air in front of us shimmered, sending off ripples of what looked like liquid flames. A hole opened in the wall, just large enough for us to pass through, though it was rapidly shrinking.

We ran into the opening and through to the other side. What I saw was nothing short of amazing. It was like a summer camp, but the most ultimate summer camp ever.

There was a semicircle of twelve cabins, all different, with braches for other cabins to line up.

I could see what looked like a climbing wall, if climbing walls were meant to be lethal. I'm not convinced that they were.

We didn't get much of a chance to keep staring around, however, because of the army that seemed to materialize around us suddenly.

They wore polished bronze armor and carried weapons that looked upleasantly...sharp. Looking at them, I got the distinct impression that they were spilt into two teams; one half wore helmets with red plumes, the other with blue. Pair of elfin, mischievous-faced boys similar enough to be twins were clutching a flag printed with a bold caduceus.

I don't know how many people were there-I'd guess near a hundred, ranging from primary-school aged to college students. They glared at us with varying degrees of hostility, fear and apprehension.

I searched desperately for a face, any face that looked friendly. I was not expecting however, to see a girl with blonde pigtails and braces. I knew that face, gone to school with her for the past several months.

"Lacy?" I gasped, shocked. "What are you doing here?"
