The Vent-Houses of the Furnace World

Overview

The vent-houses were the first lasting Kobold order. They kept the furnaces, slag-shafts, and heat-ways of the elder Ash-Furnace Civilization breathing, and some of them lived through the fire that ended it.

Its later part runs alongside The Fall of the Ash-Furnace Civilization.

Underhouse Lines Before the Furnaces

Kobolds were an old people well before the ash-furnace world needed them. Descended from the threshold elder field described in Proto-Anchor Population Map, they lived for a very long, undated age as free underhouse lines in fracture belts, cave seams, and natural vents, keeping knowledge of air, water, heat, and collapse that no surface people had reason to want.

The Vent-Houses

The ash-furnace world could not burn without that knowledge. Its furnace sanctuaries, heat chambers, and slag-shafts needed draught held in check, trapped bad air let out, and heat moved through rock without killing everyone near it. Kobold vent-kin did all of it better than anyone else.

Over generations, the furnace-masters bound them into vent-houses: hereditary Kobold houses holding named vents, shafts, and heat-ways under furnace patronage, with a protected place and a real say over whether a furnace could safely be fired, for as long as the masters chose to listen. It was the first time Kobold knowledge carried weight outside Kobold lines, and the weight was lent by someone else's world.

Overburn and Survival

As the ash-furnace world tipped into overburn, the vent-houses knew first. They kept count of shafts pushed past safe draught and furnaces fired against their warning, and their right to refuse a firing was overridden again and again. When the furnaces burst, the heat-ways became ovens. Many vent-houses died at their posts, in the shafts they had begged the masters not to fire.

Those that lived carried two things out of the fire: remnant craft of heat, vent, and draught that no one else still held, and a lasting stain from the world that had burned itself out. Later peoples would prize the first and never quite forgive the second.

The Downward Binding

The surviving vent-kin scattered. Some went to the surface margins and the ruin underlevels later Kobolds still live in. Others went down into the deep world, where Dwarven deep holds and Dark Elf houses badly needed exactly their skill.

There, shelter given to refugees became a debt, the debt became inherited bonded service, and in the harshest houses and darkest years it became captivity. This is the Kobold entry into the coerced labour of the deep, told in Deep-World Labour and Coercion, and the beginning of the medieval way of things in which Kobold skill is wanted and Kobold freedom distrusted.

Historical Significance

The vent-houses give the Kobolds a first order, a catastrophe, and the root of their medieval place: the old service-kin and patron-bound houses, the heat-vent ways of life, the dragon myths, and the reason Kobold remnant craft is both sought and feared: a vent-house secret is a treasure to a deep hold, and glass-pickers pay well for any Kobold who knows the old heat-ways.

The Kobolds are the only living people who served the ash-furnace world from inside. Their songs are the nearest thing the Medieval Era has to an eyewitness tale of the overburn, and few outsiders have ever asked to hear them. The dead furnace zones they fled are not empty: slag-tenders still rake furnaces gone cold since the fall, and salvagers who carry slag or metal out of the glassed ruins are followed by the whispers of the Fused Dead.
