I always considered that Vulkan's empire would be kinda similar to the mechanicum (less so then the Iron hands), making large amounts of weapons with their metalworking skills. This may reflect in the super-soldiers, being able to withstand large degrees of heat similar to the salamanders of Nocturne.
