The Volcano region is watched over by the Volcano Supervisor. The Volcano Supervisor wants to know that you have the necessary knowledge of the region in order to enter the volcanic region. To prove to him that you are worthy of getting access to the volcanic region, you will have to bring him a craft book related to the volcanic region as well as materials from the creatures to show that you know your way around the region. Once you bring him the items and the Volcano Supervisor deems you worthy of entering the region, he will reward you with a Moose Antlers Sword Craft Book.
