It can be a bit cliche at this point, but I'm making a modern fantasy.
The main characters are a recently deceased ghost by the name of Shelby, a Kelpie detective who's trying to solve her murder, a dryad bartender/owner who built her bar (the communal place for the main cast) out of the logged remains of her home forest, and a werewolf drug addict.
I just need every and any idea for putting things in here. Any urban fantasy ideas that you haven't had the chance to use. Anything, no matter how small.
Well I had one idea for currency. The magical government only prints 100 dollar bills/blocks/whatever you want it to be, and the way to get less valuable bills would be to break off a chunk from the 100 (or any bill for that matter). If you broke off a quarter of a 100, then you'd have a 25 and a 75. People don't normally need to break off money all that often, since people before them already did. Once you get like tons of penny worth bills, ypu can exchange them for 100s and the government will use advanced magic to turn the pennies back into 100s. Obviously money will go missing, so the government has to print brand new 100s a lot.
