Kobold: The Spirit of the Mine

The Two Faces of the Earth

The Kobold is a Germanic domestic spirit with a dual nature. Derived from Kobe (Hut) and Walt (Ruler), they are the "Rulers of the Hut." They appear as small, wizened men, often invisible or dressed in miner's clothing. They are similar to Brownies or Domovoi but are far more temperamental. They represent the volatility of the earth itself—sometimes yielding treasure, sometimes yielding poison.

The Hauskobold (Domestic)

This variety lives in the hearth or cellar. They are beneficial parasites.

• Service: They perform chores at night (cleaning stables, sweeping floors).
• Payment: They demand a bowl of porridge (grits) with butter.
• Punishment: If the payment is missed, the Kobold becomes a poltergeist. They hide keys, break dishes, and kick people while they sleep.

The Bergkobold (Subterranean)

These are the spirits of the mines. They are notoriously malicious. They mock miners, steal tools, and loosen support beams to cause cave-ins. Their most lasting legacy is chemical. Medieval miners often found ores that looked like silver but released toxic fumes (arsenic) when smelted. They blamed the Kobolds for cursing the rocks. They called this "Kobold Ore." We now know this element as Cobalt.

The Blue Flame

Kobolds sometimes appear as a flickering blue flame. This is a lure. Miners who follow the flame, believing it marks a vein of gold, are often led into deep, airless shafts where they become lost and die of asphyxiation.

The Final Warning

If you hear tapping in the deep tunnels of the mine, do not answer it. It is not a rescue team signal; it is a Kobold checking the density of the rock to see exactly where to break it to bury you. The earth provides treasure, but it demands respect, so do not tap back.
