khaine in 40k is probably a good indication of a non-overly edgy version of the god

so overall the same but less blood and more fire, less edgy blades and more greek stylings, less about murder and assassination and more about warfare and martial power, and more men since it wouldn't be strictly overseen by morathi.
it could also be easily imagined how the cult of the elven gods of the underworld wasn't as extreme as it would become later on, so perhaps there was still a certain separation between the role of the cultist and what the cultist himself would feel, drawing back again to 40k with how the eldar wear metaphorical and literal masks instead of embodying the character of khaine in their real selves, and although you're still depicting post sundering elves, so ones that are beginning to embrace the extremes, perhaps the motif of the mask could still be used if not as mere decoration as visual storytelling of them shedding that layer of protection, by having them wear broken masks, have the champions not wear masks unlike the units, or have them carry discarded masks as if they were gory trophies
