flameandoath

Flameandoath is a fictional mineral and energy resource prominent in fantasy settings. It appears as prismatic crystals that glow with a molten orange light and forms in subterranean volcanic veins. In many depictions, it can be refined into high-energy fuel or used as a catalyst in magic and alchemy.

Properties include high energy density and heat output when ignited. In inert environments it remains stable, but exposure to air can trigger rapid combustion. It emits bright heat and light, and refined forms are typically encased to prevent unwanted reaction.

Origin and occurrence: flameandoath is said to form when volatile magma crystallizes under high pressure in ember-rich zones. It is mined in careful, flame-cut processes from veins known as ember seams, with miners facing risks of spontaneous ignition and toxic fumes.

Etymology: the term combines "flame" with a fictional suffix -andoath, interpreted in-world as "bound by flame." The earliest known citation appears in the Chronicle of Ember Hall, dating from approximately the tenth century in-universe.

Uses: flameandoath serves as a principal power source for forges and engines in several city-states, and as a catalyst for rune-working. It can fuel airships and crystal batteries, though its volatility requires strict regulation and safety protocols.

In fiction, flameandoath appears in novels, tabletop games, and video games that feature volcanic warfare, exploration, or magical technology.
