Epic Warpath: Forge Father Hrungnir Magma Destroyer

Named after a beast of Forge Father legend, the Hrungnir is a colossal armoured vehicle, crewed by up to a dozen veteran dwarf warriors, and deployed wherever utter annihilation of an enemy is the only option.
 
The creature of legend was a hunter, described as being somewhere between a massive feline and a rhinorn in appearance, that once even tried to attack the Great King Frakkir. While it is hard to imagine the namesake warmachine ever being stealthy, when its magma-core engine is overcharged, the Hrungnir is certainly capable of great bursts of speed.
