"A metal of extraordinary properties. Restructures the portion of the human brain responsible for emotions. We've engineered it to remove fear."
―A simulant Aita, describing adamant's properties to Kassandra, 421 BCE[src]-[m]

Adamant ore in Atlantis

Adamant, also known as adamantine to the ancient Greeks, and later to Abstergo Industries as pathorica,[1] was a type of nearly indestructible synthetic metal used in large quantities by the Isu.

It could channel energy,[2] but among its more unusual properties were its reactivity to thought[1] and the ability to suppress fear in humans,[3] making them more susceptible to their embedded neurotransmitters[4] that could be activated by mental commands enhanced by Pieces of Eden.[1]


5th century BCE

Some time after 465 BCE,[5] once Amorges became a leader of the Order of the Ancients,[6] he was awarded The Sword of Kings, a sword crafted from adamantine. During this time, members of the Persian Order also possessed necklaces made from the metal.[7]

Around 422 BCE, the blade was broken in a battle between Amorges, his former comrade Darius, and the Spartan misthios Kassandra, and Amorges was killed.[8] Kassandra claimed what remained of the sword and took it to an artisan blacksmith 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.[7]

Shortly afterward, Kassandra experienced a simulation of Atlantis created by the Isu Aletheia, where Kassandra encountered adamant in both its raw and processed form. While exploring the city, she met Elpis, the human lover of the Archon Atlas, and was tasked with acquiring raw adamant from the Adamant Metallon without being seen.[9] After Kassandra delivered the raw ore, Elpis used it to construct an Isu device which turned her into a hybrid, hoping that it would allow her to be seen by Atlas as an equal.[2]

Modern times

In January 2012, the head of Future Technology, Álvaro Gramática researched the Shroud of Eden and analyzed the cloth's microscopic fibers. He dubbed the alloy that made up the material "pathorica", and compared his findings to other Pieces of Eden, noting their similar make up.[1]

Behind the scenes

Adamant's name is derived from the Greek word ἀδάμας and its genitive ἀδάμαντος (adamas and adamantos), often translated as 'indomitable, untameable'. Adamant and similar words, like "adamantium", are commonly used to refer to any especially hard substances.[10]
