What Are Entities?

Native to the Backrooms rather than our own reality, the term "Entity" covers a wide variety of beings, from friendly inhabitants with human-like intelligence, to mindless beasts, to creatures whose motivations and abilities are beyond our understanding. Each entity has unique behaviors, habitats, and physiological needs, catalogued by eyewitness account in our database, but when in doubt, a good rule of thumb for interacting with entities is to leave them be, for your sake and theirs. Conflicting accounts may exist in the database, and trusting your gut is the best way to survive.

Out of universe, an entity can be described as "anything living that isn't a person". As said above, Entities are as wildly varied as living things on Earth, if not more — feel free to get creative!
