Pentium
For the majority of human history, pentium appeared to be nothing more than just a pretty-looking crystal. Named for its ability to come in five varieties of colors (cyan, magenta, yellow, black, and white), most mined pentium ended up on the shelves of jewelers and the buttons of noblemen.
That is, until G. Mercer discovered its ability to unleash a burst of energy. Pentium, when treated with a specific chemical process, was able to generate energy and completely revolutionize technology. The burst left no unpleasant odors, no annoying smoke, and didn’t need water or pumps.
Mercer’s discovery led to an absolute overhaul of technology. Soon, everything was running on pentium, save for the largest vehicles like ships and trains. Washing machines, self-propelling carriages, stoves, everything ran on pentium power.
Of course, that included weaponry as well.
Before the Pentium Revolution, the vast majority of combat was fought using infantry foot soldiers bearing melee weapons accompanied by cavalry and archers. Individual soldiers could hone their strengths and become celebrated heroes capable of extraordinary feats, but those were few and far between. A country’s military power was largely defined by its ability to muster up more troops than the enemy.
After the rise of compact, efficient power, war machines like tanks and artillery appeared. The common soldier would be equipped with a single-shot pentium rifle. Swords, lances, horses, bows, and other relics of a bygone era fell out of favor. More than ever before, war was now about resources.
The most influential weapons took the form of pentium channelers. These included pentium rifles, yes, but their most recognized versions were known as pentium staves. Using the power of pentium crystal combinations, casters could launch high-powered blasts of fire, gusts of wind, and various other elemental magics. Using one required intense study. The vast majority of casters could only use one type of energy at varying levels of power. Some high-ranking court casters or those with many years of study could manage two. Only a rare few could ever cast competently with three.
Where does pentium come from?Pentium is found underground, though scientists haven't yet figured out exactly why it appears where it appears. It's mined by excavating the rock around the pentium in order to best preserve the crystal's form. big veins can take days or even weeks to fully excavate. It's why they don't really use explosives to mine it
The refinement/mining process results in pentium dust, which is about as fine as sand. Pentium dust can be repurposed into "lower quality" pentium crystals by filling in a quartz or glass container. They're less efficient from a size/energy standpoint, but also much cheaper to produce/buy.
Hunting monsters also gets you dust in fairly small quantities. Jaeger Corps sometimes supplement hunting income by selling dust they collect.
How is it used in machinery?When it's not being cast, channeling pentium simply results in a burst of clean, emissionless energy. This can then be used to move machinery.
What happens to spent pentium?Even though it is incredibly weight efficient, pentium crystals do not carry a limitless amount of energy. After all the energy from a crystal is spent, its color dulls and its internal light fades to nothing.
Used pentium crystals are often used as decorations, jewelry, or repurposed into other materials like stained glass.
What is casting?Casting is the art of using mental focus and Intent in order to enact change. MAGIC! Casters must maintain a stable mental state, visualize the change, and pour energy into their casting medium. After enough uses, the crystals in their staves must be replenished.
Using different colored pentium crystals results in different magic. Most casters are only skilled enough to use one color. Very few can use two.
Magenta - Fire, Light
Magenta Casters can create balls of flame and blind enemies. They are the most valued type of war caster. Especially skilled ones can melt metal and boil water.
Yellow - Movement, Flow, Connection
Yellow Casters can move heavy objects through force of will and shake the earth to disrupt their enemies. They are especially useful in logistics.
Cyan - Cold, Darkness, Condensation
Cyan Casters can freeze the moisture in the air around people and snuff out important lights. Paradoxically, cyan pentium is still spent, even though cyan casting more akin to removing energy instead of creating it.
Black - Weakening
Black pentium and its corresponding casting is still relatively unexplored. Nihil casting seems to be able to weaken the caster or their targets, though what exactly is weakened isn't quite so clear.
White - Un-weakening
White pentium and its corresponding casting is even less explored than its opposite. Ashen casting appears to strengthen the caster or their targets, but only after they've been weakened by nihil casting in the first place. Otherwise, nothing appears to happen.
