Secret Fruits

Exploration Stage: Harvest Festival
From: Adeline Svensson
Description: The card cheater is obviously up to something dangerous. We spotted him heading to a harvest festival in the middle of the night. Seems like odd behavior, don't you think? I tried following him yesterday, but I lost him in the dark. But he dropped something. I think it was an apple. Can you go find it?
Completed: It really was an apple! Thanks for finding it. What's so funny? It's shaped a bit like a butterfly in the night, but... oh! I remember now. This is a night apple. One of the rare fruits sold at the festival. Night apples grow on the border of fog. Don't eat them.
