Preservation Matrix

Preservation Matrix is the name given to a broad class of Blood Magic tools used, as the name might suggest, to preserve the quality of goods that would otherwise be considered highly perishable. Preservation matrices typically come in the form of boxes of various sizes that can suit a number of storage applications or thin panels that can be slotted into existing boxes or vessels.
Although preservation matrices require the expertise of those trained in blood magic, such as the fanes of the Dominion, leading to a considerably higher price point than most other comparable technologies, they are still the preferred method for long-term storage and long-distance transportation of perishable goods. Low maintenance costs and the lack of substantial ongoing costs make the technology more appealing than comparable appliances such as the icebox, which is cheaper to manufacture but has ongoing costs to the end-user as the ice blocks used therein must be replaced with regularity.
The working principles of preservation matrices are well understood, even if the fundamental mechanism by which they do this is a matter of academic conjecture. One important aspect of preservation matrices is that they work regardless of the climate or local environmental conditions.
In IldRenn and other parts of the world, preservation of foods and other perishable goods is accomplished, broadly, through a handful of strategies: refrigeration or use of cold temperatures, chemical preservation such as through pickling or embalming in the case of corpses, dessication such as by drying or smoking, salting, and aging. These methods unfortunately have an effect on the flavor, texture, appeareance, and structure of the goods being preserved.
A preservation matrix does not use any of these strategies. Preservation matrices instead directly attack the rooot cause of spoilage or decomposition. First, preservation matrices kill any insects, fungi, or other microorganism (including bacteria) that would otherwise multiply and break down the goods that are being preserved. Second, preservation matrices suppress enzymes and prevent the chemical processes that would otherwise cause the decomposition of the goods after some time in the absence of biological decomposers. Third, and most importantly, preservation matrices protect the goods from external influences, isolating them from their environment in a way that ensures no insects, fungi, or bacteria or other alien substances can affect them.
