Eidolite, also referred to as Subatonium, is a dense collection of matter, which is made by pushing quarks extremely close to one another. It is an artificially created matter, with no known natural counterparts in the universe. It is held together by the strong nuclear force, allowing for Eidolite to be very tough and hard. With its dense characteristics, Eidolite is known to be very heavy. It is almost impossible to create as well, at least in high quantities. As a result, it has not seen many uses. Even with advances in technology, Eidolite has still been shown to be very elusive and valuable.

Eidolite has pushed forward the practical use of melee combat. Its density has made it primarily applicable to ones which have suits or strong general strength. Eidolite bests another artificial form of matter, Hardlight, in the field of combat as well. It has been shown that Eidolite can shatter solid Hardlight. Unlike Hardlight however, Eidolite exhibits lower temperatures. It also unable to be made into holographic materials, though it can be made into a liquid or a gas with much difficulty.

Synthetic Eidolite

Synthetic Eidolite is incredibly easy to bend through strong force alteration fields, and responds to thaumaturgic powers very easily. It typically takes a deep violet glow, though it can be altered during the creation process in the labs. It tends to break down quickly when not kept carefully in lab conditions, appearing to crumble and diffuse into the air. Recent renditions of synthetic Eidolite have allowed it to withstand harsh conditions however, and military use is pending or allowed in several major nations. Creation of synthetic Eidolite has also been made easier in the past few millennia.

Natural Eidolite

"Natural" Eidolite is described as being made from adept Magi, being forged by high thaumaturgic prowess. Classical Thaumaturgy allows for the easiest creation of Eidolite. It has a significantly higher response to Thaumaturgy in comparison to synthetic Eidolite. In history, Magi have been reluctant to make Eidolite, as it is very strenuous and taxing on their Pylon. Natural Eidolite also has the tendancy to lose its potency if made incorrectly, much like synthetic Eidolite. This has left only a small fraction of powerful Magi to create it through the ages. However, Sedrua was very much able to create Eidolite, as Sydiah's Architects had thaumaturgic supremacy and high mental fortitude. This allowed massive production of Eidolite, surpassing that of today's output. Eidolite made by Magi are identical to one another, but there are some key differences. The most noticable of these is that each one seems to possess a signature color. For example, Moonmoon's Eidolite takes on a distinct royal blue color.


Eidolite has been used numerous times in history, holding many applications through science and militaries. The first appearances of Eidolite go back to prehistory, as Sedrua utilized it through its expansion. Sydiah's Architects proved useful for making Eidolite, and it became relatively commonplace in comparison to today. Since the regression of Sedrua however, Eidolite related technologies became obscure. Only a few of these remained as the only pieces for many years, before the War of the Final Transition saw the first synthetic Eidolite in modern history. Production was very slow until Aylathiya's Totality, where access to Sedruan technology allowed the Commonwealth to create its own, refined Eidolite.

Until the War of the Ancients, Eidolite was prized, given only to prototype military applications or science. Subsequent trade between the Quintet Payotari Association and the C.A.A. granted the latter access to advanced technology. This later granted the C.A.A. the opportunity to produce Eidolite to great extents. In the modern day, most major nations are able to make it practically. Eidolite is approximately 40 times more expensive to make than Hardlight, and its properties are marginally better overall. This has not stopped nations from continuing production however.
