The key is first obtained during the Making History quest. After the quest is completed, additional treasures can be located using the key. Once all the treasure has been found, the key will melt. If the key is destroyed before completing all the treasures, another key can be obtained from Erin for 500 coins, if the second quest has not been started. If the key dissolved after completing the Making History miniquest (i.e. by obtaining all the treasures), or if it was destroyed, then a replacement may be obtained from Jorral at the beginning of the quest.
