Karelia is a Smiler, one of the many bizarre entities that inhabit the Backrooms of reality. Unlike most other inhabitants, Karelia is quite friendly, and curious about whatever humans come across her. Due to her size and height, Karelia is immensely strong. Karelia is almost animalistic in her mannerisms, doing things such as wagging her tail in times of excitement or lowering her ears when scared. One thing always remains the same – her trademark smiling expression, which is ever-present.
