After a strict interrogation, it was revealed that they were men of Duke Leite.
The Kingdom of Leite is located upstream of the East River, adjacent to the Black Mountain Kingdom, and across the river from the former headquarters of the Fallen Legion. Since the Black Mountain Kingdom was devastated by insect plague, only the Kingdom of Leite remains upstream of the East River.
Unlike the Black Mountain Kingdom, the Kingdom of Leite is a 'normal' country with vast territory and a large population. Due to its terrain, it has a wealth of agricultural and pastoral resources, making it an agricultural country.
As we all know, while agriculture ensures a means of livelihood, wealth is hard to come by. Therefore, the Kingdom of Leite is quite poor. Compared to the elves and dwarves who have mines at home, or the human nations where handicrafts are thriving, the Kingdom of Leite is like a beggar lying on a sack of grain.
