For ten thousand years, the tech-priests of the Adeptus Mechanicus have led the Cult of the Omnissiah. From their bastion Forges on the Lathe Worlds, they control all Holy Technology in the Calixis Sector. The Lathe Worlds is a supplement for Dark Heresy that reveals the secret history of the Adeptus Mechanicus, from their mysterious founding to their current struggles against tech-heresy. What's more, players will gain access to new alternate careers such as the Mech-Assassin and Agent of the Lords Dragon, and arm themselves with weapons and gifts of the Omnissiah. And in a thrilling new adventure, your team will journey to a lost comet-station, where they'll stop renegade tech-priests from heretical experiments into the Warp!
