Labyrinth

The Labyrinth (Λαβύρινθος in Ancient Greek) was an underground maze, originally built on the island of Crete by the inventor Daedalus to hold the Minotaur in.

The Battle of the Labyrinth
As Olympus moved west, so did the Labyrinth. Percy Jackson, Annabeth Chase, Grover Underwood, Tyson, and Rachel Elizabeth Dare attempted to navigate through the Labyrinth, with varying degrees of success.

Entrances to the Labyrinth could be found all over the USA and were marked with a Delta (Δ), the symbol of Daedalus. In addition, the Labyrinth increased in size constantly. Its life force was connected to Daedalus, so when Daedalus died, the Labyrinth also collapsed.

The Labyrinth gained a mind of its own and eventually grew out of Daedalus' control, since it began to grow and expand on its own. When Percy, Annabeth, Grover, and Tyson tried to get some sleep, they could hear the walls shifting around them. The walls were also constructed of many different materials from stone to concrete. Annabeth incorrectly assumed that Daedalus' Workshop in the center of the maze would be in the oldest part of the maze, but was actually surrounded by futuristic walls and doors.

Time in the labyrinth was impossible to tell since time inside the Labyrinth did not correspond with outside time. When Percy and Annabeth fell into the Labyrinth near Zeus' fist they thought they were down there a few minutes, but they were actually missing for hours after the game ended. Once Percy, Annabeth, Grover, and Tyson found their way out of the maze after what seemed like only a few days, in reality two weeks had gone by, which caused Grover's deadline to find Pan already past. Distance was also distorted, as someone could walk around in the maze and exit almost anywhere. Percy and his group after entering the labyrinth in Texas, were able to exit at Mount Saint Helens in a very short amount of time with some help from Hephaestus' spider.

Two ways of navigating the maze are shown in the series, the first being Ariadne's String (invented by Daedalus and given to Theseus), and the second being with the help of a clear sighted mortal. Rachel Elizabeth Dare demonstrates this in The Battle of the Labyrinth, seeing a slight lighting in the floor guiding them to Daedalus' Workshop.

The Labyrinth was destroyed at Daedalus' death because it was tied to his life force. It is unknown what happened to anything in the labyrinth, but it can be assumed they were killed and the buildings destroyed.

The Roman Room

 * This room has paintings of the Roman gods at a feast on one wall. There is a fountain that doesn't work in the middle and Mosaic Tiles all over. This is where Janus tried to make Annabeth choose the left or right door until Hera intervened and sent Janus away.

The Pit Room

 * A room filled with waterfalls that lead into Tartarus. This is were Annabeth, Percy, Grover, and Tyson stayed for the night. This is also where they brought Briares after they saved him from Kampê.

The Classroom

 * This is the classroom like room that the Sphinx has her gameshow in. There was a grading machine in the corner, but Tyson ripped it off and threw it at the Sphinx. There were also a bunch of skeletons on the walls.
