Imperial Gold (formerly known as Enchanted Gold) is a blessed metal used by Roman demigods and legacies at Camp Jupiter. It is forged in their sacred temple. Chrysaor was the first to wield an Imperial Gold blade.
Imperial Gold is quite rare, as it was consecrated in Ancient Rome. The ore is specifically deadly to monsters, immortals, and their descendants. It also appears to be extremely harmful to wind-based monsters, as Jason was able to kill a group of Venti, even though Annabeth says that even with Celestial Bronze they are difficult to kill. It's also revealed that if a weapon forged from Imperial Gold is broken it would cause an explosion powerful enough to create a thirty-foot-deep crater in a mountain.
Medea states that Imperial Gold was consecrated in the Temple of Jupiter on Capitoline Hill, but its existence was an absolute secret of the Emperors. When Jason battles the giant Enceladus at Mount Diablo, Enceladus destroys Jason's weapon, Ivlivs, and as it breaks, the Imperial Gold causes an explosion that turns part of Mount Diablo into a crater.
It is stated that Imperial Gold is not as rare as Celestial Bronze, though still quite rare to the Romans. However, ever since Michael Varus lead an expedition in the 80's to Alaska, hoping to find the true meaning of the Prophecy of Seven, Camp Jupiter has experienced a major shortage of the metal. After Percy Jackson, Hazel Levesque, and Frank Zhang return from their quest to Alaska, they supply the Fifth Cohort with new Imperial Gold armor and weapons, including the Legion's Eagle Standard.
When the seven demigods talk about going to Charleston, Jason mentions that he and Reyna did a quest to salvage a secret stash of Imperial Gold torpedoes from the C.S.S. Hunley, and eventually secured them back to Camp Jupiter.
Later, when the seven demigods encounter Chrysaor, he informs Percy and Annabeth of him being the first to ever wield the metal known as Imperial Gold, though Chrysaor calls it Enchanted Gold.
