Forge World Lucius

Lucius is a world turned inside out. Where other forge worlds bury their surfaces beneath foundries and reactor stacks, the Tech-Priests of the Hollow Forge burrowed inward, carving their manufactories into the inner skin of a hollowed sphere and kindling an artificial sun at its heart. That caged star is a fusion reactor of colossal scale, its light falling upward upon the hanging forge-temples that ring the void within. By all sober reckoning the experiment should long since have destroyed the planet, yet Lucius endures, which its priesthood holds as proof of the Omnissiah's favour.

It is in the manipulation of space itself that the Hollow Forge has earned its fearsome name. Teleportation is a fickle and lethal art across the rest of the Imperium, forever threatening to scatter flesh and metal into the warp, but the magi of Lucius wield it with careless confidence. Their soldiery blink across the battlefield through hyper-localised translation devices, appearing amid the enemy without warning, while their war-engines translate into the thick of the fighting. The Titans of the resident Legio Astorum, the Warp Runners, are reckoned the only god-machines sophisticated enough to teleport directly into battle, a distinction that breeds pride in Lucius and envy among rival legions.

Such feats are possible because the Hollow Forge hoards techniques known almost nowhere else, its wargear outstripping the common patterns of other worlds. Its magi guard these mysteries with jealous zeal, so that even within the Machine Cult the true depth of Lucian knowledge remains a riddle.
