Obsidiron

When the volcanos of Thyorn erupt and the molten hot magma flows from their summit to meld with iron deposits in the rock, it creates obsidiron.
Obsidiron looks like a dark glass with a metallic shine. The blades forged from it are as sharp as Falcarro steel and twice as tough, although they weigh only a little more.
The Thyorn have mastered the material's secrets and are the only ones who know how to forge it. They use furnaces which have been channelled into the heart of the volcanos themselves. The sidsmiths have to put up with unbearable temperatures and train from birth to be able to withstand the heat long enough to get the material to a workable heat. A sidsmith will only be able to work the blade once a day and a blade can therefore take years to make. This is due to the endurance of the smith as well as the metal needing to properly cool before reheating, which can take up to thirteen hours.
Often the same blade will be passed down for centuries between a family, the strength of the material is such that an axe will be as sharp six generations on as the day it was finished.
Remarkably, the sidsmiths do not charge for their work, as artisan as it is. Instead a sidsmith will owe his allegiance to his tribe and will craft as many weapons as are necessary to arm his tribe.

Properties

Material Characteristics

It has the appearance of a black mirror, normally with multiple diamond-shaped edges. When processed it looks like the weapon of an anti-god, a souleater.

Physical & Chemical Properties

Tough and sturdy, it can hold an edge better than the finest steel.

Compounds

Created by the smelting of iron by volcanic magma, obsidian is compounded into the metal to add a crystalline microstructure which makes the metal near-indestructible.

Geology & Geography

Found in the Thorns of Thyorn.
