Percy Jackson and the Olympians

The Battle of the Labyrinth

The nature god Pan is found by Percy Jackson, Annabeth Chase, Nico di Angelo, Grover Underwood, Tyson, and Rachel Elizabeth Dare in the cave. Like many old places, there is a Labyrinth opening in these caverns. When Grover first sees Pan, he feels extremely honored and he nearly faints because he, along with so many others, had been searching for Pan for a very long time. When Pan fades, Grover feels saddened, but happy that he had finally found him, a task no other satyr has accomplished.
