Yin is cool-headed and relaxed, yet always ready to spring to action. She speaks in a slow drawl. She admires Otari, the Sea Hawk, after which her Osprey Club is named, and she makes sure that this thieves guild follows Otari’s example by stealing only from those who can afford the loss and making charitable donations to those in need. Yin believes that she has the responsibility of making sure that no truly dangerous criminals try to set up in Otari. Yin keeps her private life very private. For example, few people in town are aware that she is happily married to Barnaby, the mysterious and reclusive culinary genius who makes the food at the Crook’s Nook.
