ForgeFire

Forgefire is a term used in fantasy and speculative fiction to describe an intensely hot flame or energy source employed in metalworking. In many settings, it is depicted as a rare, controllable heat that can alter the properties of metal, fuse disparate alloys, or imbue weapons and armor with enchantments. The term combines the ordinary forge with the elemental fire, signaling heat, craft, and transformation.

Etymology and usage: Forgefire is often portrayed as a legendary or regulated resource. Some authors treat it as a physical flame, others as a magical essence, a crystalline fuel, or a runic current that travels through smithy tools. In worldbuilding, access to forgefire is typically restricted to skilled smiths, guilds, or temples, and may be linked to geographic features like volcanic regions, ore veins, or ley lines.

In fiction and media: Across novels, tabletop RPGs, and video games, forgefire enables the crafting of superior blades, armor set bonuses, or weapons with elemental traits. It is sometimes shown as changing color with temperature, emitting heat without burning the hands, or requiring ritual to stabilize its energy during forging.

Real-world use: ForgeFire as a proper noun appears in branding for metal fabrication services, welding equipment, and software tools designed to simulate smithing or metallurgy. When used in marketing, it connotes precision, resilience, and transformative power, drawing on the metaphor of forging through fire.
