The Frontrooms, also known as The Universe, is the juxtaposition of the Backrooms; a parallel Dimension that, while seemingly similar at face value, is full of many contrasting subtleties.

Like the Backrooms, the Frontrooms is a Dimension of infinite size divided into an infinite^{[See 2]} amount of distinct regions, called Galaxies. However, the Frontrooms vastly differs from the Backrooms in the following metrics:

• Stability - it is considered far stable than the Backrooms, as geometry is by default completely linear.
• Consistency - no Galaxy or area in between Galaxies is dramatically different than any other region.
• Fuzziness of distinct regions - unlike Levels in the Backrooms, Galaxies oftentimes have no well-defined boundary. Instead, they are spread or smeared over vast regions of space, with only a few more solid parts near their center.
• Intra-dimensional travel - unlike the Backrooms, noclipping does not allow travel across different regions, nor travel in one region. Instead, noclipping in the Frontrooms can only lead to the Backrooms.
• Scale - it is almost incomparably larger. A single Galaxy can be as large as 10²³ meters in radius. Likewise, Galaxies can be as far as 10²⁷ meters apart. This, along with the sheer impotence of noclipping, makes travel nightmarishly sluggish at best; practically impossible at worst.
• Depth - In the Backrooms, space is divided into clusters, then levels, then sublevels, then locations/areas. However, in the Frontrooms, space is divided into structures, then three separate tiers of clusters, then galaxies/dwarf galaxies, then star systems, then celestial bodies, and then locations/areas. In practice, this means the Frontrooms is far more complicated than the Backrooms as a dynamic system.
