Eureka!

Exploration Stage: Laboratory
From: Isabelle
Description: The ankh we found suggests that the Master learned to travel into the past. But one ankh isn't enough proof. Judging from his notes, the Master was a person who... um... let's say, was convinced of his own greatness. Such a person would surely have taken some legendary object from the past. Search for something like this in the laboratory?
Completed: You did it! This crown is very similar to the famous crown of the King of Syracuse! King Hiero asked Archimedes to determine its true composition, and as a result, with this very crown Archimedes formulated his famous principle of buoyancy... Did the Master really bring it back with him from the past?
