Steel, noon-forged
In metallurgical wizardry, a reference (generally) to ferrous metals worked at a time when natural forces best favor maximum effectiveness and potency when later used in spellwork.
Each chemical element has a time of day (depending on the planet involved) that expresses an affinity or similar close correspondence to the physical element which generally represents the chemical one. This period is referred to as the element's periodic exaltation. Any chemical element manipulated during such a period will acquire superior properties of power channeling and resistance to the forces of darkness, especially to creatures or objects that have fallen under the domination of the Lone Power.
The physical element most closely associated with worked metals is fire. (For wizardly purposes, the more active element involved in a metal's history supersedes the more passive one, which in this case is earth).
Iron and steel forged or otherwise manufactured at a time when the Sun is at midheaven -- i.e., local noon, when the Sun's presence is least interfered with by intervening masses of earth, air or water -- become unusually powerful when used as weapons against the Lone One and Its minions. Noon-forged steel is therefore a material much in demand among wizards: but getting hold of it can be difficult, in a time when so much manufacture is carried out at great distances from the end user. Sometimes a wizard will simply get lucky* at finding some, as Kit did when his Dad's old Edsel donated him his antenna. This, however, is possibly why so many wizards in earlier times got involved with blacksmithing at one point or another: to the point where one old Russian folk saying states flatly that "All smiths are shamans".
