Fiction:The Firmament/Materials

The Firmament - including Telamon and the Outer Planes - holds in it a number of notable and unusual materials, which have been used by the intelligent races of the world for a multitude of reasons.

Adamantine
Adamantine is a light blue metal which holds the honor of being among the most sought materials in the mortal world. It is famed for serving as the base for incredible artifacts, and for being able to be crafted into nigh invincible weapons and armor. Adamantine is exceptionally rare and most known deposits are highly guarded by the civilizations of the world. Notably, adamantine is fairly common in Primordial ruins, with many indications showing the precursors used the material extensively. The continent of Adaman is named after the metal, and holds the largest deposits of the world.

Cold Iron
Cold iron is a highly magical form of black-colored metal which forms in the outer space around Telamon, forming meteors which fall down upon the world's surface in rare occasions. Unlike earthly iron, it possesses unique properties which makes it the bane of fey creatures; fae creatures are particularly repulsed by it and feel extreme pain when making contact with it, which has led weapons made of cold iron to be considered the best means to destroy fairies.

Karonite
Karonite is a particular type of magical stone formed from the solidified blood of vampires; the site of the death of a powerful vampire, or several less powerful ones, often leads to the appearance of karonite. It is characterized for its deep red colour and perpetual dampness. Alchemists, sorcerers and necromancers use karonite as an ingredient for potent spellcasting, empowering the undead, and more rarely to craft equipment, as most find the stone difficult to craft without destroying it outright. Unsurprisingly, most of the world's karonite is located in Duskwood, the ancestral homeland of all vampires.

Silver
Silver is a precious metal found through most of Telamon's surface. While commonly used for jewelry, it has also been used through the ages for forging weapons and armor against certain types of cursed creatures. Silver is said to possess holy properties and is known to be among the best means to combat werecreatures and vampires, who both fear silver and cannot make use of it themselves.
