According to Grelle Sutcliffe, Drocell is butler and puppeteer who thinks he is a human being. He controls the dolls based on kidnapped little girls with the lullaby "London Bridge" from his music box in order to please his master. He has a faint realization that he is not human when he had "white stuff" falling from his ear.
Cosplay Holic reader Vea sent me a variety of Sweden's convention photos, and it would appear that I have a lot of work to do! This is one of my favorites, from Uppcon:10 which took place from the 9th to the 11th of April 2010. Thanks again, Vea!
