Percy Jackson and Charles Beckendorf discover the Ant Hill during a game of Capture the Flag. Soon afterwards Beckendorf gets captured by the Myrmekes. With the help of the Bronze dragon who is later named Festus, Silena Beaureguard, Annabeth, and Percy manage to save him.
The Ant Hill is revealed to contain massive amounts of treasure, as the Myrmekes are attracted to shiny objects, and hoard them. Beckendorf says that they have more gold and jewelry than Fort Knox.
