The city itself was a little over five hundred meters long but each sector within covered a much wider area due to the various 'space' and 'zone' expansion magics and abilities that were used to create the city in the first place.
The Beast Market, albeit abandoned for the most part, still went on for several hundred meters in every direction so there were bound to be a few people here and there.
They could either be lost, having wandered into the market without realizing it, or purposefully chose to come here to get away from any prying eyes since this was the only location that didn't have groups of individuals walking by every other minute.
