Summary
Lucius is a major forge world of Segmentum Obscurus, partnered through millennia with the Knight Houses of the Lucian Sub-Sector. Its armoured patterns — the Lucius-pattern Land Raider, the Leman Russ Vanquisher of Lucius, and most especially the patterns of Imperial Knight chassis — serve across the entire Imperium.
Lore
- Region: Segmentum Obscurus.
- Specialty: heavy armour, Imperial Knight construction and refit, primary-pattern variants of common Imperial Guard tanks.
- Heraldry: deep crimson plate trimmed in iron-grey; the Knight Houses display their own colours.
- Lucius treats the Mysteries (laws 1–8) of the Sixteen Universal Laws as the prime axiom of doctrine — animation and motive force first; the Warnings second. This places it doctrinally adjacent to Mars but in characteristic tension over priorities.
Doctrine
The covenant with the Knight Houses is sealed in the Bond of Iron: the Houses receive engines and refits, and in return swear forge-defence and expeditionary aid. The bond is older than most Imperial institutions and is, by Lucian doctrine, a model that other forges should emulate.
