The Tower Above the Seventh Shelf

You have climbed the spiral stair to Master Orvyn's workroom while he dozes in the chair below, one hand still curled around his cold tea. You are not a thief. You are a collector of curiosities, and one particular curiosity — a small lodestone carved in the shape of a fish — belongs to you. Or rather, it did, until you traded it away six months ago in a moment of weakness. Somewhere in this cluttered room it has passed through several more hands, and someone in this room knows exactly where it ended up.
