Sealed Secrets

Exploration Stage: City Hall
From: Detective
Description: I heard good things from Martha. She said that the symbols that were in City Hall may be to seal some secret. In order to reveal that secret, they need to add the missing pieces with the magic chalk that was used to draw the symbol in the first place. Let's find that chalk.
Completed: I can't believe they really found the magic chalk! Let's quickly add the missing symbols on the floor and see if we can reveal one of the secrets of the Five Wise Guardians... I can't believe it! Just as you finish drawing the symbols, part of the floor collapses to reveal a hidden door!
