The Deep Ones are beings that are worshiped by the people of Hackdirt. They are believed to live deep in the caverns of Hackdirt, hence the name "Deep Ones". The Hackdirt Brethren live in the caverns to be closer to those they worship.
- Since the Hackdirt bible contains Daedric writing, it is possible that they are a form of Daedra or the creations of a Daedric Prince.
- The Deep Ones are never seen.
- The name "Deep One" could be a refrence to H.P. Lovecraft, as one of his most famous race, save the Great Old Ones, are the Deep Ones.
