Imperial Gold

Imperial Gold is a blessed metal usually used by Roman demigods and legacies at Camp Jupiter.



Characteristics
Imperial gold is very rare, as it was consecrated in Ancient Rome. The ore is specifically deadly to monsters, immortals, and their descendants. In addition, it is extremely volatile, causing devastating destruction if broken as shown in The Lost Hero.

The Lost Hero
King Midas stated that Imperial Gold was consecrated in the Temple of Jupiter on Capitoline Hill, but that its existence was an absolute secret of the Emperors. When Jason battled the giant Enceladus at Mount Diablo, Enceladus destroyed Jason's weapon, Ivlivs, and the Imperial Gold causes an explosion that turned part of Mount Diablo into a crater.

The Son of Neptune
It was 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 had a major shortage. 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.

The Mark of Athena
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 secured them back to Camp Jupiter.

Later, when the seven demigods encounter Chrysaor, Chrysaor informs Percy and Annabeth of him being the first to ever wield the metal known as Imperial Gold.

Trivia

 * The making of Imperial Gold was a closely guarded secret of the Roman emperors.
 * King Midas states that it was consecrated in the Temple of Jupiter while Reyna stated it was the Pantheon.
 * Michael Varus lost most of the Twelfth Legion's Imperial Gold weaponry and armor in the 1980's. It was retrieved by Percy, Frank, and Hazel and given to the campers at Camp Jupiter.
 * In The Son of Neptune, it is mentioned that Celestial Bronze is even rarer than Imperial Gold by the people at Camp Jupiter. However, Imperial Gold is never used by demigods at Camp Half-Blood, meaning Imperial Gold is rare to Camp Half-Blood in the same way Celestial Bronze is rare to Camp Jupiter.
 * Imperial Gold was simply called enchanted gold until the Romans learned how to make it, officially naming it Imperial Gold.
 * The first Imperial Gold weapon was owned by Chrysaor, a son of Poseidon.
 * As it is not silver, it cannot harm lycanthropes.
