Zerek was considered a middle-sized city. It was located in the central region of the human territory, but it could be considered a city at the borders of the central region.
Most merchants traveled through Zerek when entering the central region since the lord of the city had a penchant for unique items. The Lord was very interested in a variety of goods and he would purchase everything of his interest for a high price simply because he liked it.
Zayn did know that much, and he also knew that the likelihood to meet merchants offering special goods were much higher in Zerek, creating a high interest for Adventurers to reside in the city.
