Thorasite
Thorasite is a green, crystalline substance that is used to channel and harness energy into blasts of light, also called lasers.
Structure
The average crystal is formatted with small crystallites in a lattice pattern repeating in an ordered pattern to build the crystalline shape. Thorasite, however, is no ordinary crystal. It is is actually a polycrystalline structure. What a polycrystalline structure merits is a less rigid form. It is still composed of crystallites, though their pattern is almost random and their size does not match. No two polycrystals are alike and, so too, are no two Thorasite fragments. Dwarven crystal expert Gimmund said on this,"I've looked at Thorasite clusters that sit right next to each other. I had thought the difference in structure was location, but even neighbors look different. If I had to say, I'd wager that if I checked every piece in existence, I'd never find a match. How utterly fascinating. In a way, the crystals are like us. Each similar, yet unique in what makes us ourselves."
Properties
Thorasite's special property comes from its ability to store and use light energy. This utilizes the photoelectric effect, where light energy is stored within the crystal until enough energy is built up. Once this occurs, the energy is shot out into a blast of light that burns to the touch, called a laser. The laser is quite powerful, with a single blast known to melt steel. The energy can also be harnessed for other purposes, though few attempt it as even the power of two Thorasite crystals is known to be of such overwhelming power and energy that it can kill anyone that holds it. Gimmund once studied the laser, saying:"I put a thorasite crystal in my greenhouse. When I came back a day later, it had lasered through each individual glass pane. Precise shots, still shattered the whole window. I don't envy any poor bastard who unknowingly walks by this place."This effect is possible thanks to the polycrystalline structure, which allows more energy to be stored in the space between the crystals. Energy is absorbed because of the crystal's translucent surface, which absorbs light, and while most crystals simply let out the energy, the polycrystalline Thorasite absorbs and stores it. However, while it can hold more than most crystals, it does eventually reach a limit, at which point it then shoots out its laser to free space for more energy.
cool article and a great way to bring lasers in to a fantasy world. The fact that you mentioned photoelectric effect made my happy. (worked in Nuclear power for 10 years). Main question that I have is do the lasers shoot out of the crystals in a random direction, or is where the laser shoots out a function of the crystals shape, always shooting out of the same spot for a given crystal.
Thank you so much! I will say, I got myself buried in a rabbit hole of the photoelectric effect while writing this because I found it so interesting. The lasers shoot out of a specific part in the crystal, since the crystal's shape goes into a point. There are actually two of these points on a Thorasite (In the World Forged one is on the front and one is on the back) so it just depends where the energy comes from where on one of these two points the laser will go.
