Golden House is the upper class Chammuran market. It is very upscale, and it is where very valuable and magical items are traded for other goods, and coin. Briar Moss sells his shakkans there while he and Rosethorn were staying the city. Golden House is where Evvy worked for Nahim Zineer and polished his stones. It is also where Lady Zenadia purchased a magicked larch off of Briar.
Guards are posted at the entrances in order to discourage thieves.
