Backrooms Wiki

The Commercium Foundation is a Backrooms Organisation. It is a trading and exploration organisation and are currently hiring supply runners and clerks. The Organisation's HQ is Level 1390. The precursor to this organisation was a small business and factory, in Level 11.


The Commercium Foundation is a group of explorers and traders. This organisation has its own militia and is a pioneer in backrooms navigation, having made multiple portals around the backrooms, most being tolled, but they are safer than most portals. There are rumors that the Commercium Foundation own Level 3782. The crossed out information is false. There is no evidence of this.


The company's currency is the Commercidollar (Replacing the Backdollar as it was seen as unstable, as there are levels which literally generate them.)


The Commercium Foundation was founded someday in mid-2010 by a group of explorers and traders. Commercium was a small but heavily armed group until its recruitment campaign in 2013.

Level 1390 was gained in 2012 and developed extremely fast. Commercium, being a company based on trading, is extremely rich, developing various technology and tools to navigate and survive in the backrooms. The group expanded into other levels in 2013, setting up stores and colonies.

In July, 2021, a clash between Commercium and Kriegsassociation personnel in Level 1819 gained the Organisation's first real enemy.
