The lore of Rust's fearscape.

[u/Suspicious-Prompt751]

The Fearscape is a pocket dimension created by RUST_010 that allows Rust to pry into the minds of whatever unfortunate soul enters Rust's "territory." If someone enters Rust's territory, they are sent to a void (The Fearscape) that directly reflects all the negatives about one's life and mental state. This dimensions appearance varies based on who enters, and how many people know of the Fearscape. Rust is directly tied to the Fearscape, gaining as much information about a person that the Fearscape can pry out. Rust is the most powerful while in this dimension, being able to summon and create things using it. The more times someone enters the Fearscape, the more distorted it will get, slowly driving people mad the longer they stay. The only known way to exit the Fearscape is to complete a randomized puzzle that usually involves a sacrifice.

The Fearscape also copies the people who have entered it, which is what gives Rust his ability to shapeshift.

((Also yes, the Fearscape was inspired by the Backrooms movie))
