The great prophecy is really puzzling. Fragments of the speech? What the heck is that? I mean, the Third Clan is definitely the Sagittarians, of course. But what's the new enemy rising out of the dust? I'm really confused. And I'm probably not the only one confused.

Annabeth slaps my arm and snaps me out of my daydreaming.

"Seriously?" I yell. "What in Tartarus was that for?"

"Shh!" she replies. "Be quiet in the library! And plus, we don't want people to question where we came from."

"I think they already do," I mumble.

"I did some research after I dragged you here. We need to speak to Mrs. Cloudham right now.

I roll my eyes and follow her.

We run down the stairs and find Mrs. Cloudham in her classroom, reciting some chant. She looks up and starts speaking. "You have heard of the Great Prophecy, I see?"

"Yes," Annabeth replies. "The Great Prophecy says a child of a muse hold the key. Do you know anything?"

"So you aren't clueless. Good children. I am Anadora Cloudham, daughter of Clio, muse of history," she says.

She goes on. "Nico, you possess a great power. You know the most out of anyone in The Twelve."

"The Twelve?" Nico doubts. "I'm part of the Twelve?"

Mrs. Cloudham laughs. "Nico, you have a lot to learn. You are the glue that holds the Twelve together."

"Explanation?" Annabeth asks, but Mrs. Cloudham just shakes her head. "I grew up in Lancaster, so I know almost everything about it." She pulled out a map from her desk. "You'll need this."

Annabeth gracefully accepts the old parchment. When she unrolled it, it was blank!

"Like the Marauder's Map?" she asked.

"What?" I said.

Mrs. Cloudham laughs. "Nico, you are a child of the 40's. The Marauder's Map is a map in a contemporary book series that reveals different things to different people."

Nico rolls his eyes. "Okay," he says.

Annabeth looks concerned. "Do you know anything else about Lancaster?" She asks.

Mrs. Cloudham doesn't say no, but she obviously isn't going to admit something. "One day," she sighs. "One day, you will understand…"

I glance at Annabeth, and she isn't satisfied with our history teacher's answer.

"Thank you." Annabeth mumbles.

"Good luck," Mrs. Cloudham says.

Mrs. Cloudham takes a drink of her water, and suddenly a rainbow appears in the mist. It is an Iris Message from Percy and Jason.

"Guys!" Jason yells over a waterfall in the background. "We've found the Camp of the Third Clan!"

"We've found The Key from the quest," Annabeth whispers. "Shh, because she's right here. She's our history teacher, Mrs. Cloudham."

"Great!" Percy yells over the roar. "I think we should trust them. They're our only chance."

"The leader is a girl named Emily. She's basically the daughter of Zeus and Aphrodite, I guess? Hephaestus and Artemis? Ares and-"

"Sagittar and Raia." Percy said. "It doesn't make much sense in Greek mythology, but Sagittar and Raia are both gods, so Emily is technically a goddess herself. And she leads the Camp."

"We also met one of the campers," Jason said. "Lindsay, daughter of Archaena."

Suddenly Mrs. Cloudham interrupts. "Lindslan," she says with a dreamy voice. "Daughter of Nikola Tesla. Carried on ancient traditions. Still used today,"

"Nikola Tesla?" I asked.

"Nikola Tesla." Mrs. Cloudham sniffled. "He was beautiful once, but then he became- involved...with Archaena, and-"

The bell rang.

"We better go," I told Annabeth.

We raced off to our next classes - I had music, and Annabeth had art.

"See ya," I said.
