The Entropic is an extradimensional space of unknown (possibly infinite) dimensions that exists in superposition atop our own universe. Its exact properties are unknown, and its effects are still being understood, but a great number of anomalous phenomena stem from its influence.
Many hypotheses exist as to what the Entropic may be. The most popular theory is that it is a very young universe intersecting with, or otherwise influencing, our own. Other theories suggest that it is an artefact of our universe potentially being simulated, or a manifestation of the hypothetical 'collective unconscious'.
Its discovery in ::0927 through the Entropic Grid triggered the formation of the Exotic Sciences Division.
The first thing the Syndication ever learned about the Entropic is that it imposes a grid on physical space. This grid takes the form of 'leylines', long, linear paths that accumulate interstellar plasma.
The usual properties of thermodynamics seem to break down along leylines. They act as high-entropy regions, trapping loose matter and very slightly accelerating the rate at which it loses its energy.
Grid leylines regularly intersect one another at consistent and evenly-spaced points known as Grid Points. Each are approximately 1,520 light-years apart from one another and are thought to act like collection foci, occasionally forming star systems or globules at their centres.
Since Grid leylines run parallel to both themselves and the galactic disc, they form distinct 'cubes', commonly known as the "clusters" that modern stellar cartographers use to divide regions of the Microcosm.
Recent observations from leyline probes indicate that Grid occasionally collapses to a point at a cube's centre. The phenomenon, termed "Grid convergence", has led to the discovery of many mysterious artefacts, Entropic Objects, and sometimes even lifeforms thought to be from distant galaxies or possibly other universes.
