The most notable characteristic of hiromin is not how it looks, but rather how it feels. Hiromin is cold, preternaturally so. The metal is imbued during the forging process, emitting a chill proportional to the product's mass. A medallion forged from hiromin would have a slight briskness to it, while a dire mace would be bitingly frigid.
On the surface, hiromin is a silvery-white substance with the slightest hints of violet. These hues intensify toward the core which, with sufficient volume, glows a vibrant purple. This incandescence does not permeate the surface of the metal, requiring a craftsman to employ engraving and other techniques to breach the facade to draw out a dim luminance.
The material may be smelted and reformed without losing its special properties. Once it has been "ignited," only a substantial reduction in size will dampen or extinguish the core.
Hiromin is ill-suited to projects that don't have some heft. Dainty applications are considered wasteful, lacking the critical mass necessary to invoke its frozen heart.
Restriction: Barring exceptionally dense pieces (which would likely be stationary, like a forge, architectural elements, or some industrial tool), hiromin will not glow unless the surface has been compromised in some way, exposing the core. Even when reworked, a "skin" (for lack of a better term) will form and obscure any light.
Hiromin translates as ‘frost silver’ in Gamgweth.
This material is required to be provided for alterations.
Perfected deep within the Dragon's Spine, the exact technique and elemental incantations used to create hiromin are unknown to outsiders, though the methodology likely escaped Elamiri with the exodus of the Bone Elves. What is known is that the process is highly ritualized.
