King Feathers

King Feathers are a very rare and special feather resides in garland of sorts that surrounds the neck just above the shoulder and chest area of all Dragons and is considered of extremely high value due to their extreme rarity and limited number. Because of this, if a dragon gives one of their king feathers to another, it is considered an expression of love and kindness far above any other gesture in dragon kind. As such it's not uncommon for two dragons who are dating to exchange king feathers as a symbol of their love for one other in much the same way humans would trade rings. Only the significance of this is much, much higher than even that. One does not lightly trade king feathers with another. In fact, these feathers are so valuable, that they are worth more to some dragons than their entire weight in gold. King feathers are also a different color than a dragon's normal feathers, and thus they stand out quite significantly, both on their own bodies, and on those to whom they've been given. For a dragon to place the king feather of another into their own garland is often seen as a symbol that they are spoken for by another, and thus unavailable for courtship.
