The Trials of Apollo

The Dark Prophecy

Indianapolis was visited by Apollo, Leo Valdez and Calypso while searching for the god-emperor who ruled the central U.S. They found that the emperor was Commodus, and that he intended to rename the city after himself and make it the capital of his new empire. This included leveling a large part of the city so it could be rebuilt according to Commodus' wishes. The city also houses the Waystation - a refuge for demigods, monsters and Hunters of Artemis where they could take shelter if needed.
