I genuinely don't recall fully. I know that before I reworked my story to be more dark and gritty, it didn't HAVE a name. Eventually, when I made the change, I think I just threw some words together that sounded cool? Initially, the reapers had a bigger focus than they do now, so I think the name made more sense back then.
But then I reworked the story again, leaving the name kinda meaningless. So then I worked the story around the name rather than the other way around? Which actually ended up creating an infinitely more interesting story lol
So long story short, I made sh*t up and it ended up looping around into making sense in the end!
