The faithless is a term used by The Graven in particular during the Graven Dawn uprising to refer to the followers and supporters of Baron Elias Northcrest. The term refers the fact that Baron Elias had outlawed and destroyed all buildings related to religion and the old gods in The City.
The faithless believe more in metal and stone in the name of progress, than they do in flesh and blood and the natural world.
Whereas the Graven Dawn is intended to bring faith and hope back to the people, but through violence if needs be. To this end they are fanatics and zealots and result to cruelty.
Those who choose to follow the Graven are known as the hopeful.
