vulkan's age is relevent: the salamanders are all created from his genome, so his age would be indicative of how long they might live for.

i'm assuming vulkan being a 'perpetual' is referring to him being actually immortal? this is new info to me so i'm not sure what it's referring to. but i will dispute him being 'like the emperor' - emps is a one-of-a-kind being created from, god knows how many, psykers infusing everything of their being into one soul, thus granting his body immortality. emps 'built' vulkan, just like the rest of his brethren were built, so he's nothing like emps.

but if vulkan is a perpetual then surely that means all the primarchs were/are also perpetuals? they were all built using the same d.i.y manual.
