This article is about void. The god of void is Sunya. The Void is an extraplanar realm consisting entirely of void.

Void is a form of energy. In its natural state, void is immediately useful for blocking, breaking, or otherwise canceling all forms of magic and faith. Other forms of energy can be converted into void, but when void is converted into other forms of energy, it can only create it in a form that leads to cancellation of existing energy. Void is extremely useful in physics for determining certain universal constants and for calibrating measurement devices, as sufficient continuous application of void allows experimenters to slow objects down to "absolute zero velocity", to chill objects to "absolute zero temperature", and so on. Void-powered brakes, refrigerators, and even computers were commonplace in the golden age of athak technology, along with countless other inventions. In addition to practical and scientific applications, there were also the artistic: the antiglass, a void-powered television which creates images by selectively canceling light reflection on its void-imbued screen, and the antivox, a void-powered synthesizer which creates music by taking apart existing sounds rather than laying music on top of silence.

Void is also an arcane art which allows one to manipulate void. The art is sometimes called "voidcasting" or "voidweaving", but its proper name is "void". Some creatures, such as athaks, are imbued with void, and require it to live, but have an innate ability in void, in addition to constant protection from outside magical or divine influences. Even races which are not naturally attuned to void can learn the art of void, as long as they are not magical.

• Natural Void Devices
  • Vodestone: an object which reacts to the presence of a void field by halting its motion. This is a naturally occurring "halter", one of many types of artifacts which convert void into negative physical energy. Multiple vodestones can work in tandem to affect distant forces, or to create more nuanced effects.
    • Vode-Opal: a rare type of vodestone that negates sound with ease, but other types of motion only with great difficulty.
  • Pure Elements: the few examples of nonmagical matter which can't be void-infused through any known method are collectively referred to as the Pure Elements. Each corresponds to an elemental sphere, and can be shaped or created by that sphere, but the Elements are not magical or holy in nature, and have strong innate magic resistance otherwise. The Pure Elements are unusual in that they are fixed in state and resist not just enchantment and void infusion, but all forms of adulteration or alteration. Pure Fire will continue to burn after its fuel is spent, Pure Earth or Ice won't liquefy at any temperature, and Pure Water can't be frozen, vaporized, or made into coffee. Because of these collective properties, Pure Earth and Pure Ice are highly prized as insulators and shielding in advanced technology both void and non-void.
• Void Chemistry
  • Void Oil: also known as "Athak's Blood", this is one of many forms of void-infused matter. Synthetic Void Oil is typically made from distilled water due to its purity, long shelf life, and ease of manufacture, but it also occurs naturally in a variety of forms, and is harvested for consumption by void-infused creatures, as well as for use in void engines. The chemical name for void-infused water is Irrito-Dihydrogen Oxide, and its symbol is -H2O.
    • Irrito-Antimony Pentafluoride: a type of void oil based on a powerful acid. Like its basis, -SbF5 will burn living flesh, melt most materials void-chemists would like to use for containers, and gives off dangerous hydrogen fluoride gas (void-infused, of course) when it reacts. It is also a legendary example of void poison. Smelling it will temporarily disable all magical senses. A magical being whose flesh comes in contact with -SbF5 will become tainted with void, and this taint will spread rapidly, burning as it goes. The only reliable cure for this taint is to immediately cut off all affected tissue. For a magical being that ingests -SbF5, death is certain. It is theorized that a reaction between 1L each of -SbF5 and the analogous mana-poison Thaumasine could result in an explosion on the megaton scale, but this has never been tested.
  • Jetmatter: it's more difficult to void-infuse solid matter than liquid, but the resulting material retains its existing natural properties, and will gain properties of magic resistance, void-poisoning, or energy negation. Most jetmaterials are made by taking a natural material and blessing it with void, or exposing it to intense void for a prolonged period. This results in void-infused atoms, which are stable except under extreme exposure to raw mana. Jetmatter formed through nanotechnology, however, usually consists of natural atoms bound by void-infused atomic bonds, which naturally degrade over time spent in a voidless environment. In either case, the properties of the resulting jetmaterial are usually the same.
    • Superinfusion: jetmatter is normally infused (or jetized) to the point of saturation to give it its permanent jetmatter properties. After the saturation point is reached, any additional infusion, called superinfusion, will slowly drain away, until the jetmaterial's void level returns to the saturation point. Superinfused items frequently have temporary additional capabilities with power equal to the void level of superinfusion, but these capabilities usually only last for a single use. The superinfusion capabilities of an item can only be fully realized by drawing from a massive source of void energy such as a Gift or the Void itself. Void infusion up to the saturation point usually requires faith or devices, but superinfusion can be performed by simply applying the void to the object.
    • Zantastanax
    • Jetdiamond: the simplest weapons-grade material that can be fabricated by NAMISSIS (below), chemical formula -C. Made of pure carbon, diamond is as hard as living iron, but chips easily. A blade made of jetdiamond has the usual properties of jetmatter blades: void poisoning and magical parrying, and, when superinfused, negating innate magic and disintegrating magical flesh.
  • Black Velvet: the Pure Elements are rare, but in many cases, the much more common fabric known as black velvet will suffice as a void insulator. Black velvet is made from the fibers of the black silkworm, larval form of Bombyx mundi, the black silkmoth. During the weaving process, complex void-capacitive patterns are printed on the fabric. The patterns store void and slowly redirect it toward the fringes, where it is harmlessly dispersed into the atmosphere. Black velvet protects against most forms of void poisoning, and allows athaks to touch magical items without disrupting them. The material is cheap enough to make that a handkerchief-sized scrap of it is similar in price to a small steel hand weapon.
    • Black Silk: the fibers of the black silkworm have another purpose: the fabrication of black silk. Black silk is harder to make than black velvet. Even the most sophisticated fabrication methods result in nullification of the fibers 50% of the time, down from 95% during the Brethren Dynasty. As a result, the material is quite costly and rare, and more so since most weavers would prefer to make the more predictable black velvet instead. The completed fabric is like wet paper, soft and tearable at the lightest touch, but it has an unusually high void saturation point. When saturated, it hardens and becomes super-durable, gaining motion-negating properties that make it virtually impossible to tear or pierce with hand weapons. Black Silk garments serve as excellent armor, lighter than leather, with defense equal to plate mail. Additionally, black silk retains any void it is superinfused with, remains superinfused for years, and can act as a strong void battery for its wearer. Black Silk is always in fashion among athaks, and is often worn by high-ranking officials.
• Advanced Void Engineering
  • NAMISSIS: the basis of all void technology in the modern era is the Nanoscale All-purpose Mechanical Interdependent Self-Synthesizing Irrito-System, or nano, a kind of submicroscopic robot that, in swarms, can disassemble and reassemble matter at the atomic level, to expand the swarm, or to rapidly construct the most sophisticated and powerful machines or materials that the user can conceive. Nanos build themselves mostly from jetcarbon, harvested from atmospheric CO2 and void supplied by the user. The invention of NAMISSIS has been attributed to multiple figures at multiple points in history, including the leaders of both factions in Uur Sodzul's 2nd civil war, in which nanos were first used openly for military applications, and after which their use or transport outside of the white moon was banned. Nano construction happens at such a small scale that it resembles rapid organic growth, like kudzu.
