Were you looking for the UNSC Coral Sea, a corvette that served in the Battle of Earth?

Coral is a human outer colony[1] in a system 42 light-years from Earth.[2]


At an unknown date, a Coral mining operation uncovered the tip of a Forerunner installation. The miners used explosives to excavate a depth of 30 meters, uncovering the undamaged tip of the installation. Archaeologists employed by the Office of Naval Intelligence were able to dig out about eighty meters of the complex, which seemed to be even more expansive. The complex has been described as made from metallic crystal, symmetrical to a near-atomic scale, and adorned with decorative artistic motifs.[3]

Though the details are unknown, Taylor H. Miles reports having taken part in an engagement in the Coral asteroid belt.[4]

In late September of 2552, it was reported that Coral had been glassed by the Covenant. The fate of the Forerunner installation remains unknown.[5]


Not much is known of its culture, though it was considered a taboo for people from Coral to have relationships with those from Earth.[6]

Known Residents[]


  • The Halo novel Ghosts of Onyx had a working title of "Ghosts of Coral." This led to a great deal of speculation about Coral and its background. However, it turned out to be unrelated.
  • The only known residents of Coral, Kamal and Sophia, speak about their families forbidding them to eat pork. In addition Kamal's surname (Zaman) is common in peoples of Middle-Eastern descent. Therefore, it is quite possible that Coral has a significant Middle-Eastern population.
