As Kain took another step, three possibilities immediately came to mind.
First, the Mayor's mansion had been infiltrated. Kain dismissed this idea almost as soon as it formed. If it were a simple burglary, increasing patrolling guards around the mansion would make sense, but more than doubling the guards at the gate wasn't necessary. If it were an espionage infiltration, that didn't quite fit either, as four guards versus ten wouldn't make much functional difference in checking visitors.
Second, the Mayor's mansion had been raided. This could explain the sudden increase in guards after only a few days. However, when Kain observed the guards, he noticed they seemed quite "relaxed," showing none of the typical signs of tension or heightened vigilance. If the place had just been attacked and these guards were reinforcements, their demeanor would be vastly different. So, he also ruled out this possibility.
