Most of us hadn't unpacked much, and Percy barely had anything, so it didn't take long to pack. Percy put his one change of clothes and toothbrush into a backpack.

The only one of us without luggage was Cathy, she stored all her stuff in the shadows.

THe camp store gave us $200 mortal money and 40 golden drachmas, coins the size of girl scout cookies with various gods on one side and the Empire State Building on the other. Ancient mortal drachmas had been silver, Chiron had told us, but the gods used only pure gold.

"For non-mortal transactions?" Annabeth asked. What are non-mortal transactions? I thought.

No idea! Cathy replied. "Exactly," Chiron said.

Then he gave each of us a canteen of Nectar and a zip lock bag of Ambrosia.

"These will cure you of any injury, but they are lethal to mortals," Chiron said. "Do not take too much or you will burn."

Each of us brought something to entertain ourselves, - such as an architecture book written in ancient greek for Annabeth, a PDA for Tucker and so on - our weapons, - Anaklusmos, Blepedaimōn, Phronēma and so on - and things that could be helpful - like Annabeth's invisibility cap, a fenton thermos and so on.

With a wave we began the climb up Half-Blood Hill. At the top stood a man with eyes all over his body.

"This is Argus," Chiron introduced.

"Is he going to keep an eye on us?" I asked. Cathy and Dani snorted.

"Well yes," Chiron said.
