Its story
A heavy flame projector is bolted to the forearm of a hulking suit of articulated plate. Its nozzle resembles a steel dragon's jaw, ringed with copper teeth and etched with tiny, heat-blackened sigils. A thick hose feeds from the weapon to a sealed tank fixed to the armor's back. When fired, a thumb-sized pilot flame blooms blue-white before the nozzle vomits a roaring sheet of orange fire.
Lore
Among the few who have seen it work, the device is called the Furnace Hand. Its roaring flame is said to make even the bravest foes recoil, while its armor-bound fuel system lets its wielder advance through smoke and sparks like a walking forge.
History
Legend says the projector was built for the champion of a besieged hold, whose armor let him stride through blazing streets to burn open a path for trapped civilians. It vanished after the hold's last battle, then resurfaced centuries later in a ruin beneath the Worlds Edge Mountains.
