 SCP Foundation, Macrooom's Thaumiel Project. SCPBKRM is an alternate dimension of infinite hallways. First discovered in the 1980s, SCPBKRM is sometimes referred to as the Macrooom. Due to its infinite and difficult to escape nature, SCPBKRM is a Thaumiel-class anomaly used by the SCP Foundation to contain other difficult-to-contain anomalies. Examples of anomalies contained within the backrooms include SCP106, SCP682, and a stray of SCP008. Every 14 days, a number of D-class personnel are sent into the backrooms to check on the status of the contained anomalies. These D-class are equipped with live relay cameras and ration packs to ensure they can cover as much ground as possible. These D-class are not expected to return alive. They are not provided with an escape plan. If a D-class escapes from the backrooms, they are to be terminated. Secure. Contain. Protect.
