Duncan had long since left him alone, and Gideon was engrossed in his sculpting, the large part of his anger having ebbed away in his work's absorbing him.  He would present this one, a more striking visage than the Queen's original, with a smaller nose and shorter forehead, and a more defined chin. They were all subtle changes, but they added up to a more attractive bust. If she approved this one, it would be used to make a plaster mould, which in turn would be used to make the Queen's new silver face. 

Gideon didn't hear the original knock on the door, and instead heard a repeated chime from a copper hemisphere sitting on a table near the door. It was a simple device, more magic than artifice. It detected the sound of his door's knocker from his apartment across the way, and alerted him with a chime. Sometimes it picked up more vigorous knocks from elsewhere in the nearby buildings, and it went crazy when it hailed outside, but all in all it was a serviceable device, considering its simplicity. 

He crossed the enclosed footbridge from his floating workshop to his apartment. His living space seemed starkly furnished and decorated after the downright clutter of his workshop. The contrast showed where Gideon spent most of his time. 

He opened the door, didn't immediately see the knocker below his line of sight, and was moving to close it again when he finally spotted little Felix. 

"Ha! Felix," he smiled fondly at the boy(or whatever he could properly be called), "You should get a taller hat, I almost didn't see you. Come in," he waved Felix through the door and closed it. "What can I do for you?"
