Even though this place was highly militarized, it was also very lively, both in the day and at night. Andrew and the others were surprised at the number of soldiers that had been stationed in this place when relations with the kingdom of Catarea had been neutral for centuries.
Oliver having more military experience, told them that it was probably due to the problems that Dunnas had had with Galicia. At first, they didn't understand, but after Oliver's explanation, they understood the reason.
Dunnas and Galicia had been in conflict for a long time and although Galicia has never been able to breach its defenses, that didn't mean that they hadn't lost many things during this extended conflict.
Because of that, Oliver sensed that Dunnas didn't want to suffer the same problem with Catarea even if they had never had conflicts. Countries are not managed according to what happens, but by preventing things from happening.
