The home city of the Sharznekgren Clan is Zul Sharzen, located in the western Dragonspine Mountains. The Sharznekgren are well known for the boxes of wealth they carry, but moreso for the traps that protect the contents within. The deadliest trap is known as the Troll Hug. It is a small vial of sulfur leaning against a flint strike. If a lockpick is inserted into the trapped lock, it pushes the flint against a tiny piece of stone, causing a spark. The spark then ignites a tiny fuse to the vial of sulfur. The results are deadly and can destroy a man within moments.
