"If Karen's situation is really related to the sewers, then he must be providing intelligence to that newcomer in the sewers."
Colin continued, "The janitor he escorts is different every day, so it's almost impossible for him to pass along intelligence during the escort. When we followed him today, we didn't find any dropped notes or anything else out of the ordinary.
So he must be passing the intelligence at night. At the same time, no one can fly over Thousand Masts City to the sewage outlet outside the walls without alerting the Griffin Knight Order. Therefore, he has to be entering the sewers from within the city, and from an entrance near his apartment to avoid drawing attention."
After he finished speaking, Colin looked at the barber and asked, "Do you have a map of the sewers around Karen's apartment building?"
"We do."
