It has come to my attention that y'all like these two for some reason. So enjoy a preview of some more of their stamps. I'm still trying to figure out what kind of design I want the Boss to have for when she was a demon... sooo it will take a bit longer for the update that features stamps to appear. In the mean time, thought I could share some useless trivia about the world. These are not spoilers.
Sooo, one thing I have been always about iffy about is the kind of words that I use to describe things in the story. For example, the usage of the word "demon". I mean there not inspired demons from any kind of mythology (i.e. it's not as if they are fiendish hell spawns or cunning yokai). In theory "demon" is a bit of an arbitrary word, and I could have just come up with an original proper noun, since they are a specific entity that isn't quite like most fantasy creatures.
In-universe, demons are actually a single species that is unrelated to plants or animals (including humans). They have a very alien (for lack of a better word) method of reproduction which is consistent for them all. Oh, and this isn't the kind of fiction where you can cross a human with a demon, they are biologically incompatible. You can, however cross almost any demon with any other demon. At the moment, I am currently using the word "phenotype" to describe the different kinds of demons (e.g. examples of phenotypes as read in the game, Glasswing, Knifin, Deltafoot). SOo, Mayfly's phenotype is Glasswing.
Demons also have a property which can make them sometimes turn into monsters. You don't see any of the dancing spiders turning into monsters because they aren't demons, they are animals. So back to the original question, why call them 'demons'. While they aren't fiendish spirits, I like to think that it's easy to imagine that if one were to meet a fictional creature that, in that fiction, is called a demon, that one could actually have a conversation with them. In that sense, I use 'demon' as a way to express a different kind of people than humans. Meanwhile, monsters are just scary, stronger, feral versions of demons that will attack for no reason. You cannot talk with a monster, she cannot understand you, nor communicate with you.
One note about monsters though. If a demon becomes a monster, the person that they used to be is in every sense of the word dead, the monster that she leaves behind, despite somewhat resembling the demon and inheriting her abilities and talents, is not that person, the monster has no person in her. A vicious automated corpse. And--- ok ok, I know that this sounds a little bit like a zombie, and that they kinda look like zombies, but they are definitively not zombies. 1) monsterhood is not contagious, and 2) Monsters are not trying to eat you, they want you annihilated.
Hope you enjoyed this filler post!
