The bloat thrall is crudely assembled from the bodies of half a dozen men with no regard for anatomy, only usefulness. Necrotechs then select as many as a dozen humans and animals to be skinned alive in order to provide the epidermis necessary to cover these monstrosities. The flesh, left uncured, is stretched over the thrall's mechanikal skeletal armature. Finally, the disgusting necromantic construct is fitted with a thick iron valve mounted directly into its bowels. Before each battle, massive storage tanks are latched to the valve and their bodies are pumped full of caustic sludge. The bloat thrall is an abomination in both form and function, and the armies of the living are wise to fear it.
