Moonsilver

Moonsilver is harder than steel, never tarnishes, and exhibits a special brilliance in moonlight. Though it’s the color of ordinary silver, it reflects light in ripples like troubled water, and its surface slowly shifts and pulses as if alive. Moonsilver has an affinity for the Lunar Exalted. The metal is most often found at world’s edge, on the borders of chaos. Its ores manifest in liminal places where land meets water, such as riverbanks, lake shores, sea-caves, mountainous islands, or benthic chasms. Lodes of moonsilver have grown rarer of late; the Realm has sealed off many sources, while others have simply vanished.
Moonsilver hosts a feral magic. Some moonsilver artifacts bristle with barely-restrained fury. Others are cool and subtle, their Evocations lurking like serpents. Like ever-changing Luna herself, the metal is associated with transformation and inconstancy: shapeshifting, malleability, cyclic change, reflection, opposition, duality, purification, emotion, creativity, secrecy, insight, intuition, dreams, madness, and otherworldly realms. Like Luna’s Chosen, it also has affinities for beasts, predation, pair bonds, adaptation, strength, deftness, vitality, trickery, and witchcraft. These effects are often internal to the artifact or its wielder.
Some moonsilver artifacts can modify their own shape or substance — normally an unobtrusive process, but occasionally a spectacular one. The metal’s sorcerous applications lean toward internal power and transformations, as well as transmogrification of others.
