New Phoenix

New Phoenix is a metropolitan area of Arizona, a state in the United Republic of North America on Earth. It was the fourth most populated city of URNA, after New York City, Los Angeles, and Chicago.

History
New Phoenix was originally two separate cities, Flagstaff and Phoenix. As the populations and boundaries of both cities grew to intersect, they agreed to become one large metropolis.

New Phoenix Incident
During his swift attack on Earth on July 24, 2557, the Didact was able to position his flagship, Mantle's Approach, in geosynchronous orbit above the city. Despite resistance from the UNSC Home Fleet, he activated the Composer, converting New Phoenix's population of seven million into virtual form and disintegrating their bodies within ninety seconds. Though Spartan John-117 soon destroyed the Composer, some of the harvested minds were sent to the Composer's Abyss on Installation 03 and later to Requiem via slipspace translocation, to be implanted into new Promethean Knights for the Didact's army.

During the events surrounding the Didact's attack, slipspace portal was opened in New Phoenix—evidently by the Didact's Covenant followers—allowing Promethean forces to pour through and launch an invasion on the city. An Office of Naval Intelligence research team based in the city attempted to use the Forerunner artifact known as the Conduit to close the portal and thus halt the assault.

Quarantine
Due to the nature of the Composer, the city's infrastructure remained completely intact. New Phoenix was quarantined after the holocaust and remained off-limits. The UNSC hid the details of the attack from the public, concealing it as a attack by the Covenant remnants. Six months later, however, John Sullivan, an Office of Naval Intelligence public relations officer, released a statement that the attack was not of Covenant origin.

On March 24, 2558, eight months after the attack, the city's quarantine was lifted. Doctor Ruth Charet, President of the Unified Earth Government, presided over New Phoenix's Rebirth ceremony. Spartan Tedra Grant accompanied Gabriel Thorne as he return to the city and visited his family's home.
