Sam really did make it easy for the other party to track him down.
He arrived at the next organization and when destroying it, made the merchants in that city slip and even made sure that they would agree to let him be popularized all over the place.
He made sure that the word would spread enough. He even went as far as letting some of the subordinates in the organization go and inform their supervising organization in the chain of command.
He knew that the people would be coming after him from all the different fronts because of this, but he didn't care. He just waited in the city as he slowly destroyed the organization and killed one person after another at random. The people in the city are horrified by this.
Sam expected that a person from the supervising organization would have been sent immediately when they knew of his presence, but to his surprise none of them came. They completely ignored his message.
