==Overview==

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.{{Fn|1}} A [[Production Grade]] is assigned to each forge world, being the level of production which it should aspire to reach.{{Fn|16}}
