Moustache Mansions plays an important part in the early main quest, In Wolf's Clothing, where the Hero is required to purchase two items in the shop to complete their disguise and infiltrate the Mercenary Camp. While In Wolf's Clothing is active, only the quest related items are available for purchase in the shop's inventory: the Mercenary Beard and the Mercenary Right Arm Tattoo at the cost of 500 gold each. After completion of the quest, the inventory returns to normal.
