The Mechanus are powerful sentient robots built by the engineers of the Kraftimen Guild. They were invented by the pioneer engineer Samuel Darak although some speak of this being more a discovery of processes from the Age of Power.
There are only thought to be a few dozens of their kind in existence and most are bonded to the Guild or Edelmann. Their status in the Kingdom of Kreisvolk is ambiguous as they are neither Volk or Gasten but clearly they are more than mere machines. The Grundkirk treats them as artificial constructs as they do not have the capacity for bios (life).
