What is Harbor Bay in the novel, Glass Sword?

Harbor Bay is a large city built on top of ruins in an artificial bay. It is bustling with Reds and Silvers, largely segregated into poor and wealthy neighborhoods. It is home to Ocean Hill, a royal palace which Cal once inhabited. Mare and her team come here to rescue several newbloods, as well as to obtain records from the Security Center. They are first betrayed by Crance in the tunnels under the city, then nearly caught by the Seaskull gang before escaping the Security Center. They find Wolliver Galt’s body here hanging from a statue, just before being ambushed by Maven.
