OK. I didn't understand the joke. I admit that plumes are not very fearful.

I've always heard that knights were given a plume or perhaps a scarf as a token from a lady, to signify that the knight is fighting in her name. Maybe that is overly romanticized, but I'd heard that before.

I think it's a bit romanticized, but I think also that it could have happen, but not really often.

I'm guessing that the simple feather plumes were mainly decorative, but I wouldn't be surprised if they served as identification as well to an extent. A knight might use the same color/s in his plume as he had on his heraldic device, or that of his lord/faction. So in Lego terms it means that Black Falcons would have a black white or blue plume.

This isn't something I know for a fact, it just seems to make sense. It's important to remember that there would have been different systems for heraldy, plumes etc at different times and in different countries/regions.
