Divurgo Crystal, sometimes called Cordak Crystal or Zya Crystal, was a crystalline substance found underground on the Southern Island of Powai Nui.

Decsription
Divurgo was a common find in mines, tunnels and caves in Powai Nui. Under natural circumstances Divurgo takes the form of white crystal with little clarity and around the same fragility as glass. The only odd property they normally exhibit in the wild is their weight, which is abnormally low for a crystal material.

Divurgo crystal's most notorious properties are exhibited when it is struck or hit with another object, usually a metal. This causes the stricken side of the layer to combust, usually burning around a millimeter-thick layer of the crystal off. Doing so creates an effect similar to an exothermic reaction, causing what is essentially a small explosion. This can be repeated numerous times until whatever is left of the crystal is too small to combust.

Solids objects propelled away from a combustion Divurgo crystal at speeds of at least 35 meters per second (78 miles per hour) will be engulfed and leave a trail of combusting crystal shards, usually appearing to have a yellow or orange hue. Trails left by flying objects last for short periods of time, usually around a tenth of a second or higher depending on the object's velocity.

Propellant
Divurgo crystal is most commonly used in weaponry on Powai Nui. Simple and and reliable firearms can be created, similar to Earth's muskets and using a flintlock mechanism to combust a layer of the crystal inside the firearm's chamber. This combustion is used to propel various metal pieces at speeds of around 150 meters per second, or just under half of the speed of sound. Due to the properties of objects propelled by combusting Divurgo crystal, many fired objects give the impression that a green or yellow laser has been fired from the gun.

Upon striking a target, projectiles on their own cause minor damage to metallic armor, but can still heavily damage flesh and other organic material. If the projectile strikes a harder surface such as stone or metal, however, the remaining Divurgo crystal fragments scattered around the projectile will finish complete combustion, causing further damage with a colored explosion. Divurgo-based weaponry is usually incredibly ineffective when fired into the water, and will not fire at all if the firearm is submerged. Gasses such as steam can also increase the chances that the firearm will not be able to fire correctly.

Trivia

 * Divurgo crystal's conception was in response to a minor problem discovered by CaptainLandr0ver. His series The Feral Plains, which featured the usage of firearms, had a distinctive rustic and natural theme and style to it. CaptainLandr0ver thought it wouldn't make much sense if a story which such themes had laser weaponry being utilized, and he soon came up with the basic idea for Divurgo.
 * "Divurgo" is a contraction of "Diversión con fuego", which is Spanish for "Fun with fire", referencing the material's combustion properties.
 * Divurgo was heavily based off of gunpowder, from it's properties to the way it's used in firearms.
