Iron
Kamacite and tetrataenite regmaglypt, exhibiting thumbprint pattern ablation formed upon atmospheric entry from vortices of hot gas. Known by many names amongst the barbarian tribes of the rust dunes, the endless Desolation and The Flayed Lands: thokcha, star-metal that can be harvested fallen from the firmament and lying smoking on its descent, carving vitreous furrows of fire in the sands, and leaving dimpled burning craters upon the rust dunes. Those who fear not superstition nor the curse of metallurgy have wrought the sky-iron into sacred amulets, ornate jewellery, phurba sacrificial knives, and even a form of barter-currency.
In the age of Lycurgus, thokchag thunder-iron was once formed into gargantuan mound-slabs in the treasury of the chieftains of old; the wealth of red-hot star-metal was quenched in vinegar to weaken it and render it useless - being of immense untransportable size, and of no use in warfare or ornamentation, this conceit of ancient star-metal treasury was believed to discourage all desire of theft, raiding or robbery. Faith in the success of this manner of symbolic wealth and governance is unknown, as the fate that befell the mercantile culture of that forgotten empire has been lost to memory.
