This structure is home to both the Jewelers' Guild and the Whitesmiths' Guild. It is a massive, five story building that looks like a bank vault. The doors and windows are all reinforced, and the area is constantly patrolled by heavily armed guards sent by the Spire of Feymar and the Veiled Lords.
The guild has reason to be so careful. The guild house is a central depository for jewels and precious metal works. Any guild member who wants to store something in the guild house can do so for a small fee, which varies based upon the value of the item.
The leader of the Jewelers' Guild, a gnome named Travisjmar, is rumored to be a Veiled Lord.
