Metal and Moon Dust
Moon Dust can be infused with most metals to create superior alloys often with magical properties, such as the ultra-light Mithril (silver alloy), enchantable Orichalcum (bronze alloy), poisonous Cold Iron (iron alloy), and the unbreakable Adamantine (steel alloy).
With the increased difficulty in accessing pure Dust these alloys are becoming rarer and rarer and leaning more on the legacy of older items forged from them. Additionally, New Moon can be used without being purified, but it often creates impurities in the resulting metal.
