While visiting an accountant by the name of Caesar Bilzen, Geralt snitched a soldier figurine from his host's collection. While I usually deplore such acts of petty larceny as bad manners to say the least, this time it led to quite the interesting series of events, so I am prepared to let it slide. The statuette, you see, emanated magic and our witcher sensed it might be tied to something of prime importance, so he decided to show it to Triss.
