I'm planning of giving a -possibly very unpopular - interpretation to a very loved concept in the genre of my story and I wonder if this could be see as shocking or plain stupid by the average reader.
The dilemma regards dragons (in your otherwise classical fantasy settings). If dragons were real they wouldn't be able to fly, their massive size and incredibly thick skin makes them to heavy to do so.
In my story dragons have sharp claws and thick skin as an evolutionary trait, because they live in the top of mountains and high plateaus they need sharp claws to climb those said plateaus and mountains and thick skin to survive in a rocky environment. They live in high altitude places and use their wings to glide across the sky, but not fly, once they're in the ground they stay there.
Would it be to unusual for the average reader? And if so, would this become a major weak point of my plot? More in general, is it wise to reinterpret a common trope like this?
