Exploration Stage: Scientist's Mansion
From: Rayden Storke
Description: Mr. Charles apparently erased his memory to prevent the spread of dangerous knowledge. Albert said that to restore Mr. Charles' memory, we need a crystal of a specific shape. Find the appropriate shape! Find a crystal with a specific shaped face. Search the scientist's mansion. Items may not be found immediately.
Completed: And that crystal was found in your desk? And next to it, was there a document in Mr. Charles' records? If so, this would be the crystal he chose. According to Albert, only light refracted at the correct angle, emitted from a colored crystal, can restore Mr. Charles' memory.
