The Basement is a secret level of the backrooms that was formerly theorized to exist at the bottom
floor of the backrooms, but there is no evidence that proves that there is a bottom. Due to this the former level -1 was renamed to the basement and a different level was named -1. To enter the level you must break through the ceiling of any floor including the negative levels. This level is regarded as being the most dangerous level (even more so than 3 and 6.) Despite this it is traversed by many who have the willpower to last through the level. The exits to other levels are seemingly random and unpredictable much like the entrances. Many who have passed through the basement have told tales of an unknown base, the contents and authenticity of said base has not been confirmed.
