“I'm just a kid, Chiron," I said miserably. "What good is one lousy hero against something like Kronos?"Chiron managed a smile. '"What good is one lousy hero'? Joshua Lawrence Chamberlain said something like that to me once, just before he single-handedly changed the course of your Civil War.”

“It's him," I said. "Typhon."I was seriously hoping Chiron would say something good, like 'No, that's our huge friend Leroy! He's going to help us!”

“Immortals are constrained by ancient rules. But a hero can go anywhere, challenge anyone, as long as he has the nerve.-Chiron”

“I looked at Rachel. "You're not going to do anything stupid, are you? I mean....you talked to Chiron, right?"She managed a faint smile. "You're worried about me doing something stupid?”

“Relax," Chiron told me. "Keep a clear head. And remember, you may be about to prevent the biggest war in human history.""Relax," I said. "I'm very relaxed.”

“It’s a training camp,” Leo realized. He looked at Aphros in awe. “You train heroes, the same way Chiron does?”Aphros nodded, a glint of pride in his eyes. “We have trained all the famous mer-heroes! Name a merhero, and we have trained him or her!”“Oh, sure,” Leo said. “Like…um, the Little Mermaid?”

“What was I thinking?" Chiron cried. " I can't let you get away without this."He pulled a pen from his coat pocket. It was an ordinary disposable ballpoint, black ink, removable cap. Probably thirty cents.Gee," I said. "Thanks."Percy, that's a gift from your father. I've kept it for years, not knowing you were who I was waiting for. But the profecy is clear to me now. You are the one.I remembered the feild trip to the Metropolitan Museum of Art, when I'd vaporized Mrs. Dodds. Chiron had thrown me a pen that turned into a sword. Could this be...?I took off the cap, and the pen grew longer and heavier in my hand. In half a second, I held a shimmering bronze sword with a double-edged blade, a leather=wrapped grip, and a flat hilt riveted with gold studs. It was the first weapon that actually felt balanced in my hands.The sword has a long and tragic history that we need not go into," Chiron told me. "It's name is Anaklusmos."Riptide," I translated, surprised the Ancient Greek came so easily.Use it only for emergencies" Chiron said, "and only against monsters No hero should harm mortals unless absolutely, of course, but this sword wouldn't harm them in any case.”
