Simulacra are creatures of the God-Machine intended for menial tasks.
Simulacra look like humans, but are actually extensive pieces of machinery. They are able to superficially converse with humans and fulfill basic work, but they are not alive. They have no soul, no willpower and neither virtue nor vice. A Simulacrum is unable to leave its Infrastructure and doubles as Concealment infrastructure. Should their Infrastructure be threatened, they will become agressive.
Some Demons believe that Simulacra are just highly sophisticated pieces of machinery, while others believe that they were humans once that have been taken captive and "reworked".
