Starglass is a clear, glass-like crystalline material artificially crafted by noble Everstar artisans to be used as a high quality magical focus. Starglass is extremely rare and quite expensive, limiting it to the Everstar noble families and the black market. Gestirn University documents the process for its creation well, but the Duchy forbids the knowledge from leaving its walls. Starglass is perfectly clear with only minor refractive and reflective properties. Its primary use is for lensing magic; either by reflection or refraction of spells. Starglass also gives the ability to see at great distances and at great detail, through walls and even deep into space.
Starglass is known to be grown high up in the mountains of the Duchy of Everstar, where the thin air and cold temperatures play a key role in its development. It is also speculated that the local geology contains a necessary ingredient for its creation. Though the nobility are quick to shut down any further speculation on the material’s details. The Everstar have a vested interest in keeping their primary hold on power. There is no way to buy Starglass on the open market, and it does not have a price. Only a member of the Duchy’s nobility can give you a small amount of the crystal. Authentic Starglass is rare on the black market, and deadly imitations are common with side effects rampant. It is also not known just how much Starglass the Everstar have produced, making its perceived rarity an open question.
