Hyperionite

Hyperionite is a old-world metal used by Ancient blacksmiths to create weapons and technologies so fundamentally advanced they are considered magic by peoples of the modern era. Hyperionite is known to be one of the most durable, sharp and malleable metals, being able to be crafted into almost any shape and be nigh-indestructible with an impossible edge. Currently, Hyperionite blades and weaponry are highly coveted and are the most expensive and sought after weaponry of the modern world. Each blade is said to be an echo of the gods' will and strength and they individually can be responsible for triumphant victory or solemn defeat.

History
Hyperionite blades are named this way because of the smithing icon known as Hyperios, a legendary Ancient Blacksmith that discovered and first forged these metals into lethal and destructive weapons. Hyperion wrote many tomes as a tutorial to junior smiths on how to shape blades, the surviving copies of which currently resides on the Island of Giants.

Appearance
Hyperionite resembles that of black steel with flecks of blue, its commonly compared to a deep midnight skyline as if each shard was pulled from space itself. The amount of flecks of blue dictates the strength of the blade as well as its durability.
