5th century BCE编辑
Some time after 465 BCE, once Amorges became a leader of the Order of the Ancients, he was awarded the Sword of Kings. A sword crafted from adamantine. During this time, members of the Persian Order possessed necklaces made from the metal.
In around 422 BCE, the sword was broken in a battle between Amorges' former comrade Darius and the Spartan misthios Kassandra, and Amorges was killed. Kassandra claimed what remained of the sword and took it to an artisan smith near the Oikos of the Olympians in Phokis. The smith was one of the few people who knew what adamantine was and how to forge with it. After collecting the Ancients' necklaces from all members, Kassandra had enough adamantine to repair the sword.
In January 2012, the head of Future Technology, Álvaro Gramática researched the Shroud of Eden and analyzed the microscopic fibers of the Shroud. He then dubbed the alloy making up the material "pathorica." He then also compared his findings to other Pieces of Eden, noting the similar make up.
In around 422 BCE, during her time within a simulation created by the Isu Aletheia, Kassandra encountered adamant in both its raw and processed form during her time in Atlantis. Elpis, the human lover of the Isu Atlas, tasked Kassandra to acquire raw adamant from the Adamant Metallon without being seen. Using the raw adamant she constructed an Isu device which turned her into a hybrid. She had hoped that by doing so it would allow her to be seen by Atlas as an equal.
Adamant's name is derived from the Greek word ἀδάμας and its genitive ἀδάμαντος (adamas, adamantos), often translated as 'indomitable, untameable'. Adamant and similar words, like "adamantium", are commonly used to refer to any especially hard substances.
