Adamas

Adamas, also known as the legendary metal or Aurelite is included in all seven of the legendary weapons to some degree. It is an exceedingly rare golden metal which is relatively light while still possessing outstanding hardness and overall strength.

Location
Adamas has only one known source in the southern part of A'thos but its exact location is a closely guarded secret. Stories passed down from the survivors of the Aruel Ritual suggest that the source is known as the Aruel Stone and is located in a mountainous region of A'thos.

Properties
Adamas possesses several extremely beneficial qualities for making weaponry including:
 * Strength unmatched by any known material.
 * Superb weight to strength ratio. (Its is almost impossibly strong for its weight.)
 * Minor naturally-present magical properties. For example, an adept's or healer's traditional healing cannot heal a wound inflicted by Adamas.
 * Ability to be enchanted, though only Aurelius ever succeeded in doing this.

Importance
Aside from its amazing properties, Adamas has played an integral part in shaping the history of A'thos and nearby continents.
 * Without the legendary weapons it is doubtful that Anode, Eni, and Halis would be the only three kingdoms in the southern A'thos area. Halis was the first kingdom established in A'thos, and without the founders of Anode and Eni possessing legendary weapons it is very unlikely that they would have been able to establish a foothold in the area. Without the advantage that Adamas gave, there may have been many smaller kingdoms, rather than three relatively strong ones.
 * Nearly all of Thyssha de Tyralmane's actions were influenced by her quest for Adamas. She first heard about the it from stories about Tyralmane Kel, the founder of Dre'Kel and Thyssha's home city of Tyralmane. Tyralmane Kel was a participant in the Aruel Ritual, and when Thyssha heard of the power of her Voidbringers she began to seek out the source of Adamas, which she knew was somewhere in A'thos. In her quest for the legendary metal she threw loyalty by the wayside in favor of allying with the winning side. Thyssha didn't let anything or anyone stand in her way, especially after the Terror Scythe corrupted her, and she became an extremely villainous figure.
