Annabeth's POV:
As we entered the bank, I couldn't help thinking of the architecture. Even though everything was slightly wonky, it all kind of fitted to make one imposing building. Inside I had to look twice to make sure I was seeing right.

"It's run by..." I started, before a voice by my knee cut in with: "Goblins. We are goblins."
I looked down to see one of the small creatures who had been naming the posts.
"Hello, my name is Bragnuff, how may I help you?" "We're here to get some money out of our shared vault, if you don't mind. We don't have a key though, we were told that it was being kept here for us." I said. Bragnuff told us that was no problem and, after taking a small key hanging from under the main desk, he led us through a small side door.

Thalia's POV:
"This way, you are vault number 583." Bragnuff told said in his gruff voice. "Now, everyone on the cart." When everyone was in, we started down the track, slowly gaining speed as we went. I looked over the edge and gulped. Below us, you couldn't see the bottom. Suddenly the cart went down a steep decline and jolted to a stop next to a large door with the numbers 5-8-3 emblazoned on it in gold. We all walked out on wobbly knees.

Bragnuff, however, was fine. He walked over and turned the key in its lock.
"This is your vault containing all of your money. There are three types. A Knut (Percy, Piper and Leo all laughed at this), a sickle and a galleon. It is quiet simple really. There are 29 knut's in a sickle and 17 sickles in a galleon. Therefore, there are 493 knuts to a galleon." It didn't sound simple to me, but I let it pass. Everyone filled there bags with money and prepared for the journey back to the surface.

After they left the bank, we checked their lists and decided to buy our pets first and wands last.
