The Warehouse is the third level of The Complex's path (6054). The Warehouse takes the appearance of a warehouse that is mainly empty. Occasionally, some rooms have storage racks that mostly contain food, paper, pens, etc. The Warehouse's main hazard is the lights, which shine 24/7 in the level at high power, resulting in headaches and occasionally, in the worst cases, seizures and passing out. These effects are amplified in the level, often resulting in the mental sanity of wanderers declining severely.

This hazard gives the level the Delta class, reserved for levels that may bring negative effects due to some of their physical elements.

The Warehouse is another safe level; other than the lights, it's considered a good resting and base-building level, often used by corporations to stock up on food.

In this level, a book was found in one of the chests on the racks. The note is irregular, probably not even written by a wanderer, almost as if the level itself decides to "create" these items as a distraction. Throughout the level, many instances of this note can be found, all equally written, which classifies the note as an Anomaly.

The note itself reads: "The lights hurt," with the phrase being repeated constantly throughout the entire book.

More tests are being run on the note, but regardless, its properties are still unknown.
