Mystical Signs

Exploration Stage: Cards of Fate
From: Detective
Description: As I later found out, the disappearance of a certain mafia boss brought me another step closer to the city of shadows. He and his Mauser gun both had strange symbols left on them. Find that gun. I'll show you the symbol.
Completed: The symbols left on the missing person's belongings were important evidence, but the evidence was too unrealistic for me to mention it to my colleagues. As a result, I was left alone to track down the missing person.
