Technology in the Known Worlds is not what it once was. Science fell from its pinnacle with the rise of the feudal lords and superstitious priests, stamped out by ignorance and fear. Few now dare to ignite the fires of progress, to build anew. Instead, engineers pick over the bones of the past to revive ancient war machines for their masters. Visionaries are rare, working under stigma of heresy. Their patchwork creations - whether robots or refrigerators - are considered monsters by the Church. For those who spurn the laws of the Church and construct demons of metal and lightning, there is no escape from the wrath of the Inquisition.
