Editing Rogue Trader: The Lavesgrie Exile (section)

=== The Lost Forges ===

In the distant past, the Adeptus Mechanicus maintained two great forge worlds in the Malerian expanse: Janus-Q7 and Xyra-39. Both were lost millenia ago with the collapse of Imperial power in the Expanse - Janus-Q7 to an unknown plague, and Xyra-39 to xenos attack. Their memories have echoed in the lore of the Machine Cult through the aeons since, legendary worlds where tech-priests broke boundaries and delved into the dark arts of technology. The forge world of Janus was known both for its biomantic arts, and for its great gravitic shipyard, the Cavor Pit, where techpriests assembled immense battleships and dreadnoughts within the core of the planet itself. Xyra, on the other hand, was known for its mastery of warp technology, teleport engines, and astropathic beacons. Knowledge lost with these forge-worlds set the servants of the Omnissiah back millennia.

With the Lancer Offensive, these worlds are once again within the reach of Imperial explorers. There is no doubt that a vast array of technological treasures are still to be found on the Lost Forges, for those willing to brave their dangers. Many have attempted to plumb their depths, but few have returned. Those that do speak of technological monstrosities, forgotten death traps, robotic guardians left to rot for millenia, and strange pillars that seem to warp the very laws of reality around them.
