Ucrylium

Generally considered a single element, Ucrylium is a typically purple-hued material, that takes on a number of forms, each of which exhibiting unique, if highly unusual, properties. Regardless of it's form, Ucrylium is found at a rate similar to that of materials like uraninite, and pockets have been located throughout the entirety of the Titanborne's Roost nebula.

History
Magdoran knowledge of Ucrylium began with the arrival of the Titans, who, while they did not introduce the element to the planet, arrived with immense knowledge of the material, and ways to exploit it. Their knowledge was largely lost in their departure, however, with their artefacts serving as the only remnants of this knowledge.

Without this knowledge, Ucrylium was generally impossible to be harvested or refined by the Magdoran people, with the technology to do so only being invented after the Ascension. Since that time, Ucrylium quickly came into regular use, once the applications for it were discovered.

Forms
Each form of Ucrylium generally has a unique set of properties, and occassionally a unique way of converting other forms of Ucrylium into it. Across the board, however, pure- or largely pure,- Ucrylium is resistant to excessive temperatures and impacts.

Ucrylium Ore
The most known form of Ucrylium, this ore is also the most common. It manifests as any other ore does, however the resulting compounds are extremely reactive, beyond that of even nano-thermite. This extreme reactivity was the primary reason extraction and refining were halted- with entire deposits being made practically unusable from even a single pickaxe strike. Culturally, efforts to harvest the material quickly became stigmatized, with the few attempts over the centuries resulting in great costs of life, time, and/or resources.

The ore is notably much less heat and impact resistant than other forms of Ucrylium, however both of these things trigger it's thermite properties. Extraction of this form consists of "injecting" a deposit with a superheated plasma, often contained using powerful electric and magnetic currents, the plasma itself being a specially-selected blend, designed to react with the ore compound and create a Ucrylium slag. The slag would then be extracted while it is still molten, and transported to a refinement facility, or wherever else it may be needed.

Metallic Ucrylium
Metallic Ucrylium is the second most known form, and the easiest to refine from raw ore- made by simply removing undesired elements from the slag,- however it is also the most difficult to make useful products with, due to the it's high density, and incredible resilience. Due to these properties, it is only really used in the production of advanced alloys.

Crystalline Ucrylium
Crystalline Ucrylium is the most used form of Ucrylium, and tied with the metallic form on public awareness. Crystals, including crystal threads and webs, are primarily made by reacting liquid solutions and/or salts with one another, that deposit the Ucrylium in it's desired shape. Crystals are as heat resistant as metallic Ucrylium, but is less impact resistant, and conducts electricity at scales greater than typical superconductors.

Thanks to this, it is incredibly useful in circuitry and computers, and it is relatively easy, if slow, to produce said circuits. Large-scale applications are less easy, with larger crystal structures becoming increasingly prone to defects, which at said scales often become catastrophic in a short amount of time.

Interestingly, in certain arrangements, Ucrylium crystal circuits appear to have a direct impact on their local space-time, even being able to create artificial gravity in large enough configurations. This does come with diminishing returns, however, especially when "competing" with existing gravity.

Ucrylium Dust
Ucrylium dust, also known as powder, or in it's aerated form, miasma and fog, is a unique form, consisting of highly ionized Ucrylium particles, which rarely react to anything in their environment. How these particles form naturally is generally considered to be exposure to strong ionizing radiation, however experiments with this have produced little. What is known, however, is the extreme toxicity, and mutagenic properties of the material. Inhaling, or otherwise consuming, the material typically results in a relatively rapid development of cancerous growths, however it has been known to result in other benign mutations over long times, with low-level exposure.
