Spelunking Fanatic

"Little lies underground for you except scary monsters and death. Why would you ever go very far down there??"

This is a Secret Quest that can only be unlocked by delving underground and acquiring an Essence Berry Bush. You need one in your inventory to make this quest visible; if you have What the World Came to be incomplete after completing all visible quests, this may be the culprit. This quest does not unlock any other quests, and has no prerequisites.
