This is a contextual summary of my worldbuilding efforts over the last couple months and I'm really interested to hear what you think or if you have any questions or ideas.

The "lux" particle was discovered as a byproduct of fusion/darkmatter project in a near-future Solarpunk scenario. A corporation, Helios, realized that anyone exposed to this byproduct was able to do "weird" things, and immediately kept it as hidden as possible. It disrupted all technology and electronics to some degree, but specifically transistors, which even slight byproduct of Lux completely disabled, something due to the band gap. During one of the first accidental exposures, a researcher reached for a pen and it came to their hand, then they were able to keep repeating it. Telekinesis and somatic ritual produces magical effects channeling the particle through their nervous system. They then realized they could shape the channeling through certain movements, amplifying the radiance. The scientists were left uneasy and shaky after being exposed to the particle, like caffeine withdrawal, and they'd have to keep being exposed to the byproduct of the process to be able to perform the physical rituals. After several years, many trials/mishaps, and preparation, they tried odd things under the effects, they started to realize it made the room colder, changing the temperature. They immediately started producing higher concentrations of the byproduct. The experiments eventually got to a critical point, they started realizing they could make plants produce faster, and slow the ageing of cells. The first original core members started going insane, twitching, and desperate for more lux, more power. It's addictive nature was noticed and they were able to stop all hell from breaking loose, but eventually, one of the original members tried "the big one". They wanted to be eternal, and in their madness they attempted it. At one facility, the experiment breached containment, and released the radiance across the globe, breaking the natural function of transistors, ending the world as they knew it. After, governments and entities learned about the lux particle, successfully framed as a rogue terrorist who abused the power. Helios was able to maintain its power due to their preparations, teaching the best cleanest types of magic and feeding governments and other corporations their product. The problem? The radiance didn't just end the world and make Helios all-powerful, it brought major destabilization. Magical mishaps produce a volatile byproduct, slag which cools into amber, a less pure form, has to be purified into lux carefully to make magic safer to use. Several religions formed, the Orthodox believe that using raw amber is the way it was intended, even though it makes them go crazy. Volatile magic bands form in desperation and scarcity, crazy stuff happens on the surface, good and bad. Many people don't want to touch it, some embrace it, most avoid it, are afraid of it, or are an awe of its power.
