I remembered that Hierophants spawn either by a Nekronian dying of extreme hunger or their heart being ripped out (and eaten) by another Hierophant. It’ll be cool if they have like demonic rituals to spawn a horde of them.

I should use both designs, the one on the left is called a rabid Hierophant, and those are the ones that are spawned from hunger, hence the bone-thin appearance and bigger hunger.
