Orichalcum

This warm, brilliant metal is as invulnerable and puissant as the Unconquered Sun himself. It gleams at all times as though sunlight shone upon it, its color richer and more vibrant than gold. Its nature resonates with that of the Solar Exalted, for whom its use seems natural as breathing. Veins of orichalcum ore appear close to the sun, beneath mountain peaks and alpine plateaus. Ancient savants knew methods to distill gold into orichalcum using lava and sun-focusing magic mirrors, but the relevant tools and techniques are lost.
Orichalcum partakes most purely of potencies mythically associated with the sun: raw power, unshakable strength, excellence, light and shadow, revelation, healing, divine judgment, purity, majesty, and glory. Orichalcum channels Essence and sorcerous energies better than any other magical material. While lacking jade’s pure elemental character, it can harness forceful, vibrant, or energetic natural phenomena such as floods, earthquakes, or volcanic eruptions, and can channel, absorb, and redirect elemental forces. Most orichalcum artifacts are straightforward, direct, and unsubtle. Like the sun, they claim the center of attention.
Pre-First Age orichalcum artifacts often exhibit a greenish patina, a consequence of channeling overwhelming amounts of baleful sorcerous Essence. Between this and its long association with the Solar Anathema, some Dragon-Blooded call orichalcum demon-gold and reject it as tainted with infernal power. Dynastic military forces aligned with the Wyld Hunt guard known orichalcum lodes, anticipating that returning Solars will try to gain access to their favored metal.
