Magpie Fairy - Discarded as rubbish, or accidentally lost, she finds them irresistible and adorns herself with them. Obviously because she is very tiny, the objects are depicted larger than life. I had great fun deciding which objects may have been discarded by humans and would be small enough and interesting enough for a fairy to collect. Not a traditional fairy but rather a streetwise', happy-go-lucky, modern fairy.
Fairy ~A practitioner of magic, you were blessed with the ability to attain objectives or acquire wisdom using supernatural means. You are both the master of illusion and of creation. Your powers can transform beings and objects into their most desired form, or... their harshest nightmares
From the book "The Vikings" put out by the British Museum and The Metropolitan Museum of Art on page 60 (isbn 0 87099 220 1), photographic credit to Tronheim Museum. It is described as "a whalebone line-winder incised with the figure of a bird" from north Norway, however there is no indication of how big the artifact is.
