This is a generalized map of the Manifold Sky, with cubes and tesseracts shown based on their relative connections to one another. Tesseract labels are based on Navigator's Guild nomenclature. Cube topology and geopolitical boundaries are excluded. Additional layers show various points of interest and the comfortable habitatats of the various sentient species within the Manifold. Note that the compass rose shows the progression of day and night through the tesseracts, as well as the relative position of magnetic north (green arrow).
The Manifold Sky encompasses a five-dimensional realm, with nested and adjacent cubes each a world unto itself. In the finite confines of the Manifold, factions vie for access to the limited arable land and mineral resources required to keep feeding civilization. Mercenary airships, aerostat skystations, and dieseltech auto-armor are the swords and shields of a many-layered multiverse teetering on the brink of war. The alien environments of realms adjacent to the city-cubes teem with untold wealth - and untold threats.
