I hate to be that guy, but I will point out that “man” in English can mean both a male human and humankind in general.

As in “Man is a wolf to man”: women too can be wolves and victims alike.

Or “one small step for man, one giant leap for mankind”: womankind is definitely included here.

Call it sexist. I even agree that it is. But the fact remains that, for historical and outdated patriarcal reasons, “man” in the English language, like in many others, does bear that meaning.

As for “man” being in “necromancer”, I reckon it’s like “fun” being in “fungi”: you’re not interpreting it right 🙂
