Aurae

Aurae are wind spirits that work at Camp Jupiter.

The Son of Neptune
Aurae work in the Dining Hall of Camp Jupiter. They carry plates around and supply food to the campers. Percy was given a cheeseburger and a blue soda his first night while Hazel was given shrimp gumbo, he favorite comfort food. They fly relatively close to the ground and stay invisible most of the time, meaning if someone stood they could be hit in the head with a plate, much like when Don the faun was hit in the face with a pizza. Hazel comments that they blow plates and cups around so quickly, that it looks like a delicious hurricane.

They appear once again after the battle with the Giant Army, delivering food to the campers at terminal velocity. Tyson kept ordering peanut butter and jelly sandwiches and would eat them almost as fast as the aurae could provide them while Ella was given a cinnamon roll.

Appearance
While aurae are invisible most of the time, when Percy grins after drinking his blue soda, one becomes visible for a moment and tops off his glass. She looks like an elfin girl in a white silk dress, but it is unknown if all aurae dress like this or only that one.
