Radiance Stone

Radiance Stones are small gemstones that glow with their own internal light. They are among the rarest and most precious of all jewels in Eynor, prized for their soft radiance and the mysticism surrounding their origins. Some say that they were formed by drawing out the beating hearts of great volcanoes. Others believe that they are wrought from stars plucked out of the night skies. Whatever their true origin is, it is now lost to time.   The largest and most famous of all Radiance Stones were the Stones of Heaven, which were infamously stolen from the Crown of Thirteen Heavens and since lost.    

Day and Night

  Radiance Stones come in two pure varieties, known as Daystones and Nightstones, in an addition to a large number of mixed varieties that are collectively known as Duskstones.    

Daystone

  The vast majority of pure Radiance Stones are small Daystones, which emit that characteristic soft glow. Many Daystones are a warm amber, but they can be found to glow in myriad hues. Most commonly, Daystones are fairly small, rapidly increasing in rarity as their size increases.    

Nightstone

  A small minority of pure Radiant Stones are moderate sized Nightstones. Unlike Daystones, these gems do not glow with a uniform inner light, but instead the light sources are concentrated inside a cluster of brilliant, twinkling points akin to a pool of liquefied Deep Tar. Pure Nightstones tend to be larger than Daystones.    

Duskstone

  Duskstone is a catch-all term for any Radiance Stone that is not a pure Daystone or Nightstone, and possesses some characteristics of both. Duskstones are the most common form of Radiance Stone, covering the entire gamut of hue, size, and luminosity possible for a Radiance Stone.   Most Duskstones combine the characteristics of Daystones and Nightstones, for example being divided in two with one half glowing as a Daystone with the other half containing brilliant points like a Nightstone. Another example is a Nightstone that has been bisected with a thin radiant band through the middle.   Duskstone is also used for otherwise pure Radiance Stones that have large flaws within the crystal, such as internal fractures or inclusions of foreign material.    

Counterfeit Stones

  The soft light of a Radiance Stone is not to be confused with the often dim and sickly viridian glow of Marcuire, or of the halo of luminant turquoise that suffuses flooded Sinterblock cisterns. In each case the radiance originates in a different location. In the case of Marcuire the glow originates on the opaque surface rather than deep within, and this difference combined with the characteristic green colour is a tell-tale give away when a Marcuire painted pebble is falsely passed off as a true Daystone. In the case of Sinterblocks, the characteristic turquoise halo only appears surrounding the blocks, and then only when submerged in water.
