Aaron Lightfoot, proprietor of Lightfoot's Apothecary and Thaumaturgical Supplies, has an order to fill, requiring silver creen scales and powdered dragon eggshell. The problem is that dragons and silver creens are largely considered to be mythical or at least particularly rare. Aaron visits an animal handler, Siesseth, in the Bazaar, for help, and learns of a creen-catcher by the name of Piper, who might be able to assist in Aaron's search.
