DOA Recording Studios

DOA Recording Studios is the main entrance to the Underworld. It is located in Los Angeles, California. DOA stands for "Dead On Arrival".

The Lightning Thief
Percy, Annabeth, and Grover use this entrance to enter the Underworld to confront Hades.

Appearance
The doors say in the lobby: NO SOLICITORS. NO LOITERING. NO LIVING. Inside the lobby, Muzak music is playing, the carpet and walls are steel grey, black leather furniture and an elevator. Charon is on a raised podium.

Charon's Boat
When someone dies, they will be taken into an elevator going down by Charon (if he allows them), then they sail across the River Styx.

Trivia

 * The original entrance to the Underworld was the Cave of Avernus.
 * DOA means "Dead On Arrival," which most people arriving there are.
 * Adults must pay a fee for the trip on Charon's boat (usually charged to their last cable bill or with American Express).
 * People who can't pay stay in the lobby (hoping for a free trip). Many have stayed for a couple of hundreds of years, while some have only been there for a few days, and some might even still be waiting after three thousand years if you look. Most of these are children.
