Stormcast Eternals
The Stormcast Eternals, also simply called Stormcast, are superhuman, nigh-immortal warriors whose souls have been magically Reforged by the will of the God-King Sigmar. They now serve as the primary weapons of the Grand Alliance of Order in retaking the Mortal Realms from the forces of Chaos in the Age of Sigmar.
Stormcast Eternals are not born, but made, forged from mortal souls of great honor and courage, alloyed with the celestial energies of the Cosmic Storm, and beaten into the living weapons of Azyr, the Realm of Heavens, upon the Anvil of Apotheosis. All Stormcast Eternals were once paragons of humanity. Many were warriors or wizards, but not all, for the skills of war can be taught, while honour, courage, or simple faith cannot.
There are three stages to the creation of a Stormcast Eternal. In the Chamber of the Broken World, the chosen are blasted apart by heavenly lightning, their souls painstakingly remade before entering the Cairns of Tempering, wherein their spirits are blended with the Gifts of the Gods. The final stage is the Anvil of Apotheosis, whereupon they are smote by the World Hammer, infusing those who endure with a portion of the God-King's own divine might. Few indeed are the mortal heroes who can survive the rigours of the magical process called "Reforging," but those who do emerge are effectively immortal, death bringing about merely dissolution into the celestial lightning from whence they came, blasting their soul back to Azyr to commence the punishing ordeal anew.
Most, if not all, Stormcast Eternals are forged from a human soul. Though they still resemble humans, albeit in a highly idealised form, their physical traits have changed so much as to be almost unrecognisable from what other mortals consider human. Worse yet, the Reforging process gradually robs them of their humanity piece by piece, widening the divide between what they once were and what they have become. Essentially, this means that the Stormcast Eternals are actually considered to be a different species from normal humans.
