Last thing someone mentioned how in the intro of Undertale there is a human with a flame scythe despite the fact humans cannot use magic. Any theories on that?

unironically for over the decade I've been in this wretched fandom I cant stop myself from thinking about what Humans were like during the war of the Monsters. I dk why but something about that magic scyth just tickles my eternal 15 year old brain every time I see it
