Adamantium

Adamantium is a material noteworthy for its heavy weight and complete immunity to anima. Adamantium is incredibly rare and in short supply across Harmonara, putting its value incredibly high among every sovereign state, particularly the Third Ikkaran Empire where the metal is prized by the government. Though conflicts with aspects of a celestial are rare throughout history, it has been passed down for many generations that adamantium is the only efficient way to harm them.

Trivia

 * Adamantium is also the name of a music genre developed by an orcana magician.
