Flesh Colossos

After many devastating battles, the grey hordes of the Undead could be seen scouring the aftermath, stumbling around the battlefield collecting the still-fresh corpses of the fallen, stripping the flesh for them to use in unholy rituals. Once they have collected enough such power, they are able to grant existence to a Flesh Colossos, a massive clump of decaying flesh fuelled by the suffering souls of all those comprising its monumental frame. Luckily for the realms of the living, they are seldom seen roaming the lands, but on the rare occasions of their appearance, the ground begins to tremble beneath the steps they take. They are the fuel of many nightmares, immune to all forms of pain, not willing to halt their advance until the unholy flame of their beings has been extinguished – a feat often requiring entire legions: and many more that have tried and failed before.
