Exploration Stage: Collector's House
From: Detective
Description: The collector talks about justice, but isn't he the one who committed the crime? For now, let's gather more information about the amazing properties of fog. We can figure out how to use it later. The clues must be surprising too...heavy feathers, for example!
Completed: These feathers are heavier than metal... I didn't know such things existed! It seems that the fog has changed its properties. Then we should be able to get the next part of the collector's records.
