Can you please clarify how this is Fallout related?

They’re a sort of ghoul you could say, I wanted to give them the depiction of burnt skin without the nasty occasional look

You could say I was inspired by the Glowing One.

It'd be pretty cool if we saw other mutations in future Fallout games that create a new sentient sub-species, without ripping off the Dark Ones from Metro.

Looks like some kind of Children of Atom deity.

Appalachian it does
