Character from Prince of Thorns by Mark Lawrence
A fire elemental — or something like one — a creature of pure flame bound by Builder-era forces, devastating and barely controllable.
Ferrakind is a creature of fire — immensely powerful, barely intelligent in any human sense, and devastatingly destructive when unleashed. It represents the intersection of magic and Builder technology that defines the Broken Empire's supernatural landscape. It may be a weapon from the Builder era given magical sentience, or a magical being empowered by Builder-era energies. The distinction doesn't matter when you're burning.
Fire given form — a shifting, roaring presence of flame that consumes everything it touches. Whether Ferrakind is a magical entity, a Builder-era weapon, or something in between is deliberately unclear. It burns. That is its nature and its purpose.
