Hi everyone! I'm new here, but I have a question. A tiny problem that is sort of keeping me from writing right now. Hope someone will help I'm writing this Fantasy novel and there is two worlds. Our own contemporary world and then a fantasy dimension within our world. That's where the fantasy creatures lives. And, I have this idea that one of the main characters, of the fantasy species, should be from a very wealthy family, but then I came to realize that I don't have a currency in mind for that world, and I have a hard time coming up with something. Would you say that it is a necessity to have a currency to be able to have a wealthy family? If so, how do you make something like that up? Is it as simple as giving it a name? Or would I have to create an economic system and everything?? Thanks. And have a good day!
