Minor Anomalous Object 000000 is an archetype of materials, termed "Black Rock" for their shared unique appearance. Specimens have been discovered as far back as pre-Empire times, but have not been officially catalogued until the formation of the Exotic Sciences Division in ::0927.
Instances of 000000 in the form of rough chunks and fragments typically manifest nearby, alongside, or encasing Entropic Objects. In the latter case they take the form of 'geodes'. Their average size ranges between 200g and 2.3kg; extreme cases of sand-like grains and enormous near-ton boulders exist, however.
000000 is visually comparable to black marble with cobweb-like gold seams. When brought to either's melting point, however, the corresponding material quickly vapourises and demanifests. It is also softer, with a Mohs hardness of 2.5.
Samples of 000000 (-39, -52, -99, -104, and -218) are on display in the Enjil Blue Quadrant Exotic Sciences Museum.
