Certain areas of the level may lack light, with the temperature in these areas averaging 18°C (64.4°F) instead of the level's usual 22°C (71.6°F). These regions are generally large and unfurnished, with non-food items typically found as resources. There are no marble tiles with speakers in these rooms. To exit the level, the transition to Red Rooms occurs when the red rooms transform the level. The passage leading to the rusty metal door guarded by the F.B.P.T. takes wanderers to Level 22.
