The majority of a Forge World's solid ground surface is covered in thousands of years of built-up, massive industrial complexes: great machine factories, production centres, huge volcanic furnaces, skyscraping chimneys, abyss-like quarries and the great workshop-fortresses of the Collegia Titanica. No other world can match the quality and quantity of a forge world's output.[1]
The population of a Forge World is invariably immense, the majority directly involved in the industry of the planet, laboriously working in factories and involved in heavy mining. The result of the planet's complete industrialization means its ecosystem has been completely destroyed. The air is saturated with toxic gases and rivers flow with toxic run-off from factories. In many cases, even seas and oceans have been dried up to make room for more factories. However, the output of forge worlds is absolutely vital to the Imperium as a whole.[16]
