• Requires The Serum: Creepweed Thorns
• Leads to The Serum: Ashes from the Shrine

This task will require two trips to the Thunderwalker Boneyard. First, I need you to gather some horns and a specific vine, Gravevine, that grows in quantity within the confines of the Boneyard. Once you have brought me these items, we may continue.

• Starts with Morpheus Silvertongue
• Ends with Morpheus Silvertongue

Good to see you again so soon. Yes, those are the vines and enough horn to do what I must.
