Aherne Sutton Dark Heresy
Ambulon is a bizarre sight indeed, claimed by many to be a hive in in its own right. The entire city is mounted on the back of a machine that slowly walks across the unstable rocky regions in the center of Scintilla’s main continent. The machine is extremely old, and was almost certainly already on Scintilla when the Imperium conquered the Calixis sector. It is probably a pre-Imperial artifact, constructed by a civilisation that fell before the foundation of the Imperium, though some claim it is a relic of pre-Heresy terraforming technologies. Certainly the skeletal ruins of moving constructs similar to Ambulon dot the central steppes. Ambulon’s unusual form affects every aspect of life in the city, from the industries that employ it’s middle class citizens to the city’s customs and folklore.
