I'm writing an action/urban fantasy graphic novel about a teenager who also happens to be a Grim Reaper, but I'm stuck on how to provide exposition about the world/ magic system when my main character and most of my supporting characters already know about this world (so there wouldn't be any need to explicitly explain it to an unknowledgable POV character, because there isn't one). Any ideas?
Maybe just casually mention locations or descriptions? For example, “Ugh, the shade of red my mum painted my room has always bugged me,” or “Oh look, the cafe is busy today. I would’ve thought it would be empty, seeing as the restaurant across the street has a kids-eat-free deal today.” Or something like that. Obviously, it wouldn’t be of a cafe for you, but it’s something I use for my stories when that applies. Hope this was helpful!
