Others' Island (spoilers all books incl RWC)

[Nuytsia]

Possibly the copper feather signifies dragons? A ‘feather’, after all, is merely Kennit’s take on what the object is, especially as he would have been more interested in what the object meant for his dreams of kingship rather than speculating on its beauty?

Or an actual scale dropped by a copper dragon?
Or in some way linked to the feathers found on the beach that went into the rooster crown? (not sure how, probably only in some symbolic way which is lost on me!)
