In the heart of every lodestone is the earth’s rage, tamed and refined into a glimmer of its ancient power. To wield one is to hold a fragment of the world’s soul—and its wrath.
—Arbiter Daelion, Polytechnic Engineer, from The Artificer's Legacy
Refined from numenic ore, a volatile and radioactive mineral, lodestones are self-sustaining magical batteries, capable of generating tremendous energy. Once refined, the ore’s unstable properties are harnessed and contained within metallic spheres that radiate a charged aura of magical energy, allowing the lodestones to float effortlessly above the ground.
The properties of a lodestone vary based on the ore’s origin. Size correlates directly to the energy stored within, while the color of the lodestone’s aura reflects the specific magical properties of its ore. These versatile power sources have revolutionized fields such as transportation, weaponry, and Clockwerk technology, allowing for feats of engineering that rival even the creations of the High People. However, they are not without peril. An unsheathed lodestone, uncontained by its sphere, is lethally unstable, capable of vaporizing matter on contact and unleashing devastation on an unthinkable scale.
As a lodestone expends its magical energy, its aura dims, and its radiant colors fade to black. When fully depleted, it falls to the earth as inert cold iron, its usefulness gone. The refinement process is arduous and fraught with danger, as numenic ore’s radioactivity makes mishandling potentially fatal. As such, only the most skilled metallurgists and alchemists dare to work with it, and their craft is as much art as science.
The Fulcrum, a vast production facility owned by the Kingdom of Vanis, is the heart of lodestone refinement. There, Vanisian metallurgists produce the world’s most advanced and efficient lodestones, often under grueling conditions. This monopoly on lodestone production grants Vanis significant political and economic leverage, fueling its formidable Clockwerk armies and sustaining its ascetic way of life.
