Extremely cool. Lotta neat concepts here. I am curious though, where does the term helldiver come from? Is it like an ODST from halo, where these are essentially orbital airborne soldiers? Or is diver referring to the aquatic variety? Amazing picture, and entirely worth the fave!
Oh, and British SF do rule. First to the party, so to speak. If the description is implying your brother inlaw serves, please thank him for me.
the idea for the characters comes from a short story by craig herbertson called heavenmaker. dont know about the odst stuff tho they could have somthing like that
